Fundamentals and processes

Precision graduations: the foundation for high accuracy

The high quality of HEIDENHAIN products
depends on special production facilities
and measuring equipment. Masters andsubmasters for scale manufacturing areproduced in a clean room with special
measures for temperature stabilization andvibration insulation. HEIDENHAIN develops
and builds most of the machines it needs
for the production and measurement oflinear and circular scales, including thenecessary copying equipment.

The heart of a HEIDENHAIN encoder is its
measuring standard, usually in the form ofa grating with typical line widths of 0.25 µm
to 10 µm. These precision graduations are
manufactured in a process invented by
HEIDENHAIN (e.g. DIADUR or METALLUR)
and are a decisive factor in the function
and accuracy of encoders. The graduations
consist of lines and gaps at defined inter­vals with very little deviation, forming struc­tures with very high edge definition. These
graduations are resistant to mechanicaland chemical influences and can tolerate
vibration and shock. All measuring standards
have a defined thermal behavior.

Competence in the area of linear and angularmetrology is reflected by a large numberof customized solutions for users. Amongother implementations, they include themeasuring and test equipment developed
and built for standards laboratories andthe angle encoders for telescopes and­satellite receiving antennas. Of course,
the products in the standard HEIDENHAIN
product program profit from the knowledge
gained.

Phase gratingsSpecial manufacturing processes make itpossible to produce three-dimensional
graduation structures, possessing defined
optical characteristics. The structure widths
are in the range of a few microns down toquarters of a micron.

METALLUR
With its special optical compositionof reflective gold layers, METALLUR
graduations show a virtually planar
structure. They are therefore particularly
tolerant to contamination.

SUPRADUR
Graduations manufactured with the
SUPRADUR process function optically likethree-dimensional phase gratings, but they
have a planar structure and are therefore
particularly insensitive to contamination.

OPTODURThe OPTODUR process produces
graduation structures with particularly highreflectance. Its composition as an opticallythree-dimensional, planar structure issimilar to the SUPRADUR graduation.
MAGNODUR
Thin magnetically active layers in the
micron range are structured for very fine,magnetized graduations.

Length measurement

Length gauges
Length gauges from HEIDENHAIN feature
integral guideways for the plunger. They areused to monitor measuring equipment, inindustrial metrology, and as position
encoders.
• Accuracy grades as fine as ±0.1 µm• For measuring steps of down to
0.005 μm (5 nm)• Measuring lengths of up to 100 mm• High measuring accuracy• Available with automated plunger drive• Simple mounting

Exposed linear encoders
Exposed linear encoders from HEIDENHAIN
operate with no mechanical contact between
the scanning head and the scale or scaletape. Typical areas of application for theseencoders include measuring machines,
comparators and other precision devices,
as well as production and measuring
equipment, for example in the semicon­
ductor industry.
• Accuracy grades of ±0.5 µm and better• For measuring steps of down to
0.001 μm (1 nm)• Measuring lengths of up to 30 m
• No friction between scanning headand scale• Small dimensions and low mass
• High traversing speeds

Sealed linear encoders
Sealed linear encoders from HEIDENHAIN
are protected from dust, chips and splash
fluids and are ideal for operation onmachine tools.
• Accuracy grades as fine as ±2 µm• Measuring steps of down to 0.001 µm• Measuring lengths of up to 72 m
• Fast and simple installation• Large mounting tolerances• High acceleration loading• Protection against contamination

Under the designation functional safety,
HEIDENHAIN offers encoders with purely
serial data transmission as single-encoder
systems for safety-related machines andsystems. The two measured values are
already formed independently of eachother in the encoder, and are transmitted
to the safe control via the EnDat interface.

The aluminum housing of a HEIDENHAIN
sealed linear encoder protects the scale,scanning carriage and its guideway fromchips, dust and fluids. Downward-oriented
elastic lips seal the housing. The scanning
carriage travels along the scale on a lowfriction guide. It is connected to theexternal mounting block by a coupling thatcompensates unavoidable misalignment
between the scale and the machineguideways.

Mounting block

Absolute linear encoders from HEIDEN­
HAIN require no previous traverse to provide
the current position value. The encodertransmits the absolute value through the
EnDat interface or another serial interface.
The recommended measuring steps
listed in the table refer primarily to position
measurements. Smaller measuring steps,
which are attained through higher inter­
polation factors of sinusoidal output signals,
are useful in particular for applications inrotational speed control, e.g. on directdrives.

Sealed linear encoders are available with• Full-size scale housing– For high vibration loading– Up to 72 m measuring length• Slimline scale housing– For limited installation space– Measuring lengths of up to 2040 mm(for measuring lengths starting from1240 mm, mounting via mounting sparor tensioning elements)

Scanning carriage

With incremental linear encoders, thecurrent position is determined by starting at
a reference point and counting measuring
steps, or by subdividing and counting
signal periods. Incremental encoders from
HEIDEN­HAIN feature reference marks,
which must be scanned after switch-on
to reestablish the reference point. This
process is especially simple and fast with
distance-coded reference marks.

LC, LF, LS, LB sealed linear encoders
With full-size scale housing

Linear encoders with full-size scale
housing are characterized particularly byhigh tolerance to vibration.
Absolute linear encoders of the LC 100
and LC 200 series provide the absolute
position value without requiring any
previous traverse. Depending on theversion, incremental signals can be output
additionally. The LC 100 can be mounted
to the same mating dimensions as theincremental linear encoders of the LS 100
series and features the same mechanicaldesign. Because of their high accuracy
and defined thermal behavior, LC 100 and
LS 100 series linear encoders are especiallywell suited for use on numericallycontrolled machine tools.
The incremental encoders of the LF typefeature measuring standards with relatively
fine grating periods. This makes them
particularly attractive for applications
requiring very high repeatability.
The LS 600 series incremental linear
encoders are used for simple positioning
tasks, for example on manual machine
tools.

Simple installation with mounting spar
The use of a mounting spar is of great
benefit when mounting slimline linear
encoders. It can be fastened as part of themachine assembly process. The encoder
is then simply clamped on during final
mounting. Easy exchange also facilitates
servicing. Moreover, installation with amounting spar significantly improves theencoder’s acceleration behavior.

For measuring stations and multipoint inspection apparatuses

HEIDENHAIN length gauges are charac­terized by high accuracy together withlarge strokes of up to 100 mm. They featureplungers with integral bearings andtherefore serve as compact measuring
devices.

Plunger actuation
The plungers of the length gauges withmotorized plunger actuation are extended
and retracted by an integral motor. They areoperated through the associated switchbox.

The HEIDENHAIN-CERTO CT length
gauges are used predominantly for produc­tion quality control of high-precision partsand for the monitoring and calibration ofreference standards.

Length gauges with plunger actuation bycoupling have no plunger drive. The freely
movable plunger is connected by a separate
coupling with the moving machine element.

The HEIDENHAIN-METRO MT 1200 and
MT 2500 length gauges are ideal for
precision measuring stations and testing
equipment. The ball-bush guided plunger
tolerates high radial forces.
The primary applications for the MT 60
and MT 101 are incoming inspection,
production monitoring and quality control.
They are also used as high-accuracy
position encoders, for example on linear
slides or X-Y tables.
Thanks to their very small dimensions,the HEIDENHAIN-ACANTO AT and
HEIDENHAIN-SPECTO ST series length
gauges are the product of choice formultipoint inspection apparatus and testing
equipment.

HEIDENHAIN-ACANTO• Online diagnostics• Protection up to IP67
• Absolute scanning
HEIDENHAIN-CERTO• For highest accuracy• Low thermal expansion through thermallyinvariant materials• High-precision ball bearing guide

The length gauges with plunger actuationby the measured object or with cabletype lifter feature a spring-loaded plungerthat is extended in its resting position.

HEIDENHAIN-METRO
MT 1200 and MT 2500
• High repeatability• Various gauging force variants• Various possibilities for plunger actuation

The MT 1281 and ST 1288 length gauges
are available with various gauging forces.
Particularly for fragile materials this makes
it possible to measure without
deformation.

HEIDENHAIN-METRO
MT 60 and MT 101• Large measuring ranges• Plunger actuation by motor or coupling• Ball-bush guided plunger

On the length gauges with pneumaticplunger actuation, the plunger is retracted
by the integral spring at its rest position.
It is extended to the measuring position by
application of compressed air.

Angle measurement

Mounting variants
In angle encoders and rotary encoders withintegral bearing and stator coupling, thegraduated disk of the encoder is connected
directly to the shaft to be measured. The
scanning unit is guided on the shaft via ballbearings, supported by the stator coupling.
As a result, during angular acceleration of
the shaft, the stator coupling must absorb
only that torque resulting from friction in
the bearing. These angle encoders therefore
provide excellent dynamic performance.
Thanks to the stator coupling, the systemaccuracy includes the error of the shaft
coupling. Other benefits of the stator
coupling are:• Simple mounting• Short overall length• High natural frequency of the coupling• Hollow through shaft is possible

Angle encoders
HEIDENHAIN angle encoders arecharacterized by high accuracy values in
the range of angular seconds and better.
These devices are used in applications
such as rotary tables and swivel headsof machine tools, indexing heads,
high-precision angle measuring tables,
precision devices in angular metrology,
antennas and tele­scopes.
• Line counts: typically 9000 to 180 000• Accuracy: from ±5” to ±0.4”• Measuring steps as fine as 0.000 01°
or 0.036” (incremental) or 29 bits,
i.e. approx. 536 million positions per
revolution (absolute)Rotary encoders
Rotary encoders from HEIDENHAIN serveas measuring sensors for rotary motion,
angular velocity, and when used in conjunc­tion with mechanical measuring standards
such as lead screws, for linear motion.
Application areas include electrical motors,
machine tools, printing machines, wood­
working machines, textile machines, robots,
elevators and handling devices, as well as
various types of measuring, testing andinspection devices.

Absolute angle encoders and rotary
encoders require no previous traverse to pro­vide the current position value. Singleturn
encoders provide the current angular position
value within one revolution, while multiturnencoders can additionally distinguishbetween revolutions. The position values
are output, for example, over the purely serial,
bidirectional EnDat interface. It enables
automatic configuration of the higher-level
electronics and provides monitoring anddiagnostic functions.

• Line counts of typically 50 to 5000
• Accuracy grades: to ±10” (depending on
the line count, corresponding to ±1/20 of
the grating period)• Measuring steps: as fine as 0.000 01°.
Particularly for photoelectric rotary
encoders, the high quality of the sinusoidal
incremental signals permits high inter­
polation factors for digital speed control.

Under the designation functional safety,
HEIDENHAIN offers encoders with purely
serial data transmission as single-encoder
systems for safety-related machines andsystems. The two measured values are
already formed independently of each otherin the encoder, and are transmitted to thesafe control via the data interface.
With incremental angle encoders androtary encoders, the current position isdetermined by starting at a reference pointand counting measuring steps, or bysubdividing and counting signal periods.
Incremental encoders from HEIDENHAIN
feature reference marks to reestablish thereference point.
Incremental rotary encoders with
commutation signals provide the angular
shaft position value—without requiring
previous traverse—with sufficient accuracy
to correctly control the phases of therotating field of a permanent-magnet threephase motor.

18

Angle encoders and rotary encoders withintegral bearings for a separate shaft
coupling are designed with a solid shaft.
The recommended coupling to themeasured shaft compensates radial andaxial tolerances. Angle encoders forseparate shaft couplings permit higher
shaft speeds.

Angle encoders and rotary encoders
without integral bearing operate without
friction. The two components—the scanninghead and the scale disk, drum or tape—are
adjusted to each other during assembly.
The benefits are:
• Little space required• Large hollow-shaft diameters• High shaft speeds possible• No additional starting torque

Because of their high static and dynamic
accuracy, the RCN, RON and RPN angle
encoders with integral bearings andintegral stator couplings are the preferred
encoders for high-precision applications
such as rotary tables and tilting axes. The
measuring standard is usually a circularscale with DIADUR graduation. For theencoders with stator coupling, the specified
accuracy includes the error resulting frommounting. For angle encoders with separate
shaft coupling, the coupling error must be
added to find the system accuracy.

standard and the magnetoresistive
scanning principle make them particularly
tolerant to contamination.

Absolute position measurement

The attainable system accuracy depends
on the eccentricity of the graduation to thedrive shaft bearing, as well as the radial
runout and wobble of the bearing.
Typical fields of application include machines
and equipment with large hollow shaft
diameters in environments with large
amounts of airborne particles and liquids,
for example:• Rotary and tilting axes for ERM 2280
and ECM 2400
• C axes on lathes for ERM 2410,
ERM 2420 and ERM 2480
• Main spindles on milling machines for
ERM 2484, ERM 2485 and ERM 2984

ECN, EQN, ERN rotary encoders
With integral bearing and mounted stator coupling
Up to IP66 protection
HEIDENHAIN ECN, EQN and ERN rotary
encoders with integral bearing and statormounted coupling operate by photoelectricscanning. They are characterized by theirsimple mounting and short overall length.
Possible applications range from simple
measuring tasks to position and speed
control on servo drives. The hollow shaftof these encoders is slid directly onto andfastened to the shaft to be measured. During
angular acceleration of the shaft, the stator
coupling must absorb only that torqueresulting from friction in the bearing. Rotary
encoders with stator coupling therefore
provide excellent dynamic performanceand a high natural frequency.

KCI, KBI rotary encoders
Without integral bearing

With its KCI 100/KBI 100 and KCI 1300/
KBI 1300 series, HEIDENHAIN provides
inductive encoders for compact robot
motors. The circular scales can be screwfastened or press-fit onto a motor shaft.
The KCI/KBI inductive rotary encoders aredesigned for direct installation. Consisting
solely of a scale and scanning unit, they
do not have a housing. This enclosure-lessdesign saves considerable space andenables easy integration into the application.
The KCI/KBI rotary encoders are also avail­able as dual encoders in Dplus versions, withfront and back scanning for two separate
circular scales. As a result, these encoders
provide position feedback both upstream
and downstream from the gearbox with asingle encoder.

Machine tool control

Controls for milling machines
With its TNC controls, HEIDENHAIN offers
a complete product line for all common
types of machines in the area of milling:from a simple three-axis CNC millingmachine to a highly complex machine withup to 23 axes—a TNC control is always
the right choice. Thanks to their flexible
operational design and practical functions,
the TNCs are particularly suitable for thefollowing applications:• Simple milling, drilling and boring
operations• Machining in a tilted working plane• Complex 5-axis operations• High-speed cutting operations• Milling-turning operations• Jig grinding• Gear hobbing or skiving
TNC controls are versatile and offer theright programming function for any task.
Thanks to its HEIDENHAIN Klartext format,
the user need not learn G codes or special
programming languages. Instead, thecontrol guides the user with conversationalquestions and tips. Ease of use is also pro­
moted by clear, unambiguous key symbols
and names. Each key has only one function.
Even if you are used to G-code program­ming, however, the TNC is still the rightcontrol—you can simply enter the G codes.
TNC part programs have long lives because
they are upwardly compatible. Programsfrom older TNCs can usually also run on the
new models. When moving up to a moreadvanced TNC, the user merely builds on
what he already knows.

Controls for lathes
Lathe controls from HEIDENHAIN havebeen proving themselves for years both on
standard and complex lathes as well as on
turning centers. Many shop-compatible
functions support you optimally during:• Conventional lathe operations• Machining with driven tools• Machining with the C and Y axes
• Full-surface machining with dual spindles• Machining with the B axis
HEIDENHAIN lathe controls are extremely
flexible: whether you need only single cycles,
short program sequences or complete
NC programs—you only need to select theappropriate operating mode.
Program creation with smart.Turn is par­ticularly easy and convenient. The straight­
forward fillable-form input provides graphicalsupport, meaningful dialogs, and a logicalcheck of entries.
You can also reuse NC programs of older
HEIDENHAIN lathe controls, such as the
CNC PILOT 4290, on the CNC PILOT 640.
With a convenient import filter you cansimply load the programs into the newcontrol, and then continue using them on
the CNC PILOT 640.

Quickly and easily to the finished partThe operational design of the milling andlathe controls is tailored to the needs of theuser and therefore offers you the greatest
possible flexibility in program creation.
When programming at the machine, allrequired inputs are guided by practiceoriented prompts and questions while
highly expressive help images support you.
For standard operations and even complex
applications, users can draw on a wide
variety of cycles for machining, coordinatetransformations and machine setup.

High quality and productivity
Thanks to intelligent motion control,
HEIDENHAIN controls enable shortmachining times with perfect workpiecesurfaces and very high workpiece accuracy.
The bottom line is an increase inproductivity: unit costs are reduced without
affecting accuracy and surface quality.

HEIDENHAIN controls can be programmed
remotely equally well on a CAD/CAM
system as on a HEIDENHAIN programming
station.

Manufacturing complex components
precisely
Regardless of whether the workpieces are
simple or complex—HEIDENHAIN controls
offer the appropriate functions. With them,neither are operations in a tilted plane achallenge, nor is multi-side or full-surface
machining. Simultaneous machining withup to five axes is an especially strong pointof HEIDENHAIN controls. With special
control strategies, functions for processmonitoring, and compensation of productioninduced disturbances, you can also manu­
facture components with complex geome­tries exactly, with process reliability, andefficiently.

Directly on the control, users can open DXF,
STEP or IGES files created on a separate
CAD system. They can then extract contours
and machining positions as needed. Thisnot only saves time otherwise spent on
programming and testing, but you can also
be sure that the adopted data is exactly inaccordance with the design engineer’s
specifications.
User-friendly and practicalThanks to the robust design optimized forthe application, HEIDENHAIN controls are
ideally suited for a harsh work-day environ­ment. The intuitive screen displays tips,
dialog boxes, program steps, graphical aids
and tiles. All texts are available in numerous
languages. The 3D illustrations repre­
senting the machine, fixtures, tools andworkpiece simplify programming andprovide valuable aid for verifying the
program.

Electronic handwheels and programming stations

HR 510, HR 520 and HR 550 FS portable
handwheels
The axis keys and certain function keys
are integrated in the housing. This way you
can switch axes or set up the machine at
any time—and regardless of where you
happen to be standing. The HR 520 also
features a display for the position value, thefeed rate, the spindle speed, the operating
mode, and other functions, as well as
override potentiometers for the feed rateand spindle speed. You can enjoy unlimited
freedom of movement with the HR 550 FSwith radio transmission. Its features
correspond to those of the HR 520.

The TNC7, TNC7 basic, TNC 640 and TNC
620/TNC 320 programming stations allow
you to create Klartext programs away fromall the noise of the shopfloor, just as if you
were working at the machine. With the
DataPilot CP 640 and the DataPilot MP 620
you can also use smart.Turn, G codes andcycles to create programs for your HEIDEN­
HAIN lathe controls.
Creating programs
The programming, testing and optimizing of
HEIDENHAIN Klartext or G-code programswith the programming station substantiallyreduces machine idle time. You do not needto change your way of thinking. At the
programming station you program on thesame keyboard as at the machine.

The vision systems for tool inspection
consist of two components:• Camera with two objectives (VT 121,
VT 122)• Touch-operated PC software (VTC)The VT 122 is available in two variants:• With connections through the base plate
for mounting on a prepared machine, or• With lateral connections for variable
cable routing

The vision systems enable tool imaging
during machining. Besides documenting
tool status and wear, the following
applications are possible as well:• Tool inspection before critical machining
steps• Optimization of cutting parameters• Optimization of NC programs• Breakage detection• Tool inspection after expiration of tool lifeYour benefits:• Automated imaging during machining• Time savings, since the tool stays in themachine• Compact system, even usable with verylarge tools• Rugged design• Controlled compressed-air cleaning• PC software for configuration andevaluation also on the TNC

Training with the programming station
Because the programming stations are
based on the respective control software,they are ideally suited for apprentice andadvanced training.

TNC training in schools
Since they can be programmed withG codes as well as in Klartext conversational
format, the programming stations can also
be used in schools for TNC programming
training.

Tool and workpiece setup and measurement
TS workpiece touch probes

The TS workpiece touch probes from
HEIDENHAIN help you perform setup,measuring and inspection functions directlyon the machine tool.
The stylus of a TS touch trigger probe isdeflected upon contact with a workpiecesurface. At that moment the TS generates
a trigger signal that, depending on themodel, is transmitted either by cable orover an infrared or radio beam to thecontrol.
The control simultaneously saves theactual position values as measured by themachine axis encoders, and uses thisinformation for further processing. The
trigger signal is generated by means of awear-free and highly reliable optical sensor
or piezoelectric sensor.

Touch probe with radio and infraredtransmission for machines with automatic
tool change:• TS 460: universal touch probe
Compact dimensions, energy-saving
mode, optional collision protection andthermal decoupling• TS 760: highly accurate touch probe
High probing accuracy and repeatability,
low probing force
Touch probe with cable-bound signaltransmission for machines with manual
tool change (e.g., grinding, turning andmilling machines):• TS 750: highly accurate touch probe,
cable-bound, radial or axial cableconnection• TS 150/ TS 260: cable-bound touchprobe, radial or axial cable connection

HEIDENHAIN offers probe styli with various
ball-tip diameters and stylus lengths.
With a TS touch probe and a KKH calibration
sphere from HEIDENHAIN, you can calibrate
the rotary axes of your machine and mini­
mize measurement error in the machine’s
kinematic description. These calibration
spheres are also well suited for 3D calibrationof the touch probe.
Benefits of HEIDENHAIN touch probes• Idle time reduced through high probing
speeds• High-quality probing saves repeat
measurements• Reliable workpiece cleaning removes
chips before probing• Convenient TNC operation with SE 661
transceiver unit
• With TS 460: collision protection adapter(optional) prevents damage to machineand spindle, and reduces heating of theTS through the spindle• With TS 260: direct connection with any
downstream electronics; no interface

TT and TD tool touch probes

Reduce scrap, minimize rework, cut down on
idle time and increase machining accuracy:
the TT touch probes and TD 110 tool breakage
detector from HEIDENHAIN enableefficient and reliable tool inspection andmeasurement.
Due to their rugged design and high degreeof protection, these tool touch probes canbe installed directly within the machinetool’s work envelope. Tool inspection ispossible at any time: before machining,
between two machining steps, or after
machining is done.

SE transceivers

Touch probes
The TT 160 and TT 460 are 3D touch trigger
probes for tool measurement and inspection.
The disk-shaped probe contact of the TT isdeflected during the tactile probing of a tool.
In that instant, the TT generates a trigger
signal that is transmitted to the control,
where it is then processed further. The
trigger signal is generated by means of awear-free and highly reliable optical sensor.

The following transceivers are available forwireless signal transmission:• SE 540: for integration in spindle head;
only infrared transmission• SE 640: infrared transmission• SE 660: shared SE for TS and TT;

Measured value acquisition and display

Digital readouts
HEIDENHAIN digital readouts for manuallyoperated machine tools have universal
application: in addition to standard tasks on
milling, drilling and boring machines andlathes, they also offer ideal solutions formany applications on machine tools andspecial machines—in fact all machines
where axis slides are moved. This includes
radial drilling machines and rapid radial
drilling machines.
Digital readouts for manual machine tools
increase your productivity. They save timeand increase the dimensional accuracy of
the finished workpiece while offering very
user-friendly operation.
Practice-oriented functions and cycles areavailable for various applications. The
distance-to-go display feature with graphic
positioning aid allows you to approach thenext nominal position quickly and reliably
simply by traversing to a display value ofzero. The digital readouts speed up smallbatch production—repetitive machining
sequences can be saved as a program.

Evaluation units
HEIDENHAIN provides the appropriate
evaluation unit for each type of application.
They offer numerous functions for measured
data acquisition and statistical evaluation of
measured values. For automation solutions
the results of the measured-data evaluation
can be processed further by integrated
switching functions. The splash-proof front
panel and the sturdy cast-metal housing
make evaluation units from HEIDENHAIN
impervious to the harshest of everyday
shop conditions.

User-friendly environment
Digital readouts and evaluation units withintegrated display are specially designed
for user friendliness. Typical characteristics:• Optimally readable, graphic flat panel
display• Intuitive operation using touchscreen or
keyboard (depending on the product)• All-in-one device with compact outside
dimensions• Sturdy aluminum housing• Reference mark evaluation for distancecoded and single reference marks• Problem-free installation, maintenancefree operation• Fast payback with economical use

Signal converters
Signal converters from HEIDENHAIN
enable the flexible adaptation of interfaces
for encoder signals to the requirementsof your application. Depending on theapplication, additional signals (such astemperature-sensor signals) may beprocessed and transmitted to the down­
stream electronics.

Evaluation units and digital readouts from
HEIDENHAIN feature a data interface
for further processing in the higher-level
electronics or simply to print out themeasured values.

Precise manufacturing made easy:
Together with linear encoders from HEIDEN­
HAIN, the digital readouts measure theaxis movements directly. The backlashcaused by mechanical transfer elements
such as lead screws, racks and gears
therefore has no influence.

Evaluation units for metrology applications
Measuring and testing tasks

Evaluation units for measuring and testingtasks are ideal for:• Measurement equipment• Adjustment and inspection equipment• SPC inspection stations• Multi-gauging fixtures• Mobile data acquisition• Positioning equipment

The GAGE-CHEK 2000 evaluation unit is anindependently operating device with a builtin screen and robust housing. It features
special functions for metrological collection
and the statistical evaluation of measure­ments, such as sorting, minimum/maximum
value recording and the storage of measure­ment series. These data make it possible
to calculate mean values and standard
deviations, as well as graphically display
them in histograms or control charts.

Inspection and testing devices

The GAGE-CHEK 4000 SW evaluation
software is particularly suitable forpositioning tasks on measuring andpositioning equipment. You can easilyload position values to Excel using a
LOG function.
GAGE-CHEK 4000 SW is very versatile formulti-gauging fixtures with up to six axes.

Inspection and testing devices from
HEIDENHAIN
HEIDENHAIN encoders provide all of theinformation needed for setup, monitoringand diagnostics. HEIDENHAIN offers theappropriate PWM inspection devices and
PWT testing devices for encoder adjust­ment and analysis. The PWM inspection
devices can be used universally. They have
low measuring tolerances and can becalibrated. Testing devices have larger
measuring tolerances, fewer available
functions, and cannot be calibrated.

HEIDENHAIN encoders can usually beconnected either directly or via signal
converters to a number of different
downstream electronics.
HEIDENHAIN therefore offers encoders
and signal converters with various
interfaces. The testing and inspection
devices from HEIDENHAIN also support
various interfaces, which makes theirapplication more flexible (see overview
for the PWM 21 and PWT 101).
