Easy measurement of inside diameter for thick workpieces

Continuous small hole and outside diameter measurement

A 3-step motorized sliding axis enables easy inside diametermeasurement of thick workpieces by avoiding interference, without
having to replace the stylus as in conventional models. Furthermore, it
allows for continuous automatic measurement of squareness, runout,etc. by combining inside diameter and upper surface measurements.

Allowing the stylus angle to take 2 states, 0° or 10° enables continuous,
combined measurement of small holes and outside diameters while
avoiding workpiece interference. Furthermore, measurement can be
conducted with the workpiece remaining in the same position whenmeasuring repeatedly while changing the stylus angle since changes instylus tip position are automatically recognized by ROUNDPAK.

Best-in-class maximum of 30 rpm. The
ability to acquire measurement data
without waiting for the 0° position incurvilinear measurements reduces the
positioning time by about 40% comparedwith conventional models (in-housecomparison), dramatically improving theperformance.

Provides a wide variety of parameters as standard features, including those for roundness / cylindricity, as well as flatness and parallelism.

Visualizes analyzed surface roughness and contour by using a wide variety of graphic technologies.

Allows for switching to measurement-only screen(run-only measurement screen), where operators
are only allowed to run part programs.

Equipped with an offline teaching function, partprograms can be created without even having
actual measurement workpieces, andmeasurements can be virtually run in the 3D
workpiece view window. Warnings regarding riskof collision can also be displayed.

Allows for setting of X and Z axes travel ranges toprevent collisions with workpieces as a result of
operational errors. Travel ranges can be grasped
at a glance by displaying the software limit
information bar on the measurement control
screen.

Wide variety of data operation functions

3D parameter analysis

Lead (twist) analysis

Allows for visualizing the measurement target in

MeasurLink
Reduction of defective products by“visualize product quality”
Measurement results enable various statistical processing operations.
Furthermore, displaying the control chart in real time enables early
detection of possible future failures (cutting tool wear, damage,etc.). In addition, connecting this program to an upstream network
environment as a terminal enables the construction of a system forcentralized management.

The customer can create measurement reports incustom formats by specifying how the analysis
results will be displayed, as well as the sizes andpositions of graphics.

APPLICATION

for practically any workpiece
ROUNDTRACER EXTREME has applications

Camshaft

Bearing

Pulley based CVT

Camshafts require high-precision measurement because they control
the opening and closing of inlet / outlet valves that improve the
combustion efficiency of engines. Measurement of cam shape, surface
roughness, and roundness, which previously required multiple
measuring instruments and setup, can now be efficiently conductedusing a single measuring machine.

The surface roughness of bearings requires high-precision
measurement since it has direct impact on the coefficient of friction.
A single ROUNDTRACER EXTREME can not only efficiently measureroundness, but also surface roughness with high accuracy.

Pulley based CVTs are components of automotive continuously variabletransmissions that contribute to fuel efficiency and smooth travel.
Measurement of surface roughness of the tapered portion, roundness,and contour. This previously required multiple measuring instruments
and setup but can now be efficiently conducted using a single
measuring machine.

Tool holder

Electric motor cores

Spline

The tapered portion of tool holders requires high-precision
measurement since it needs to pair with the main axis of machine
tools. High-precision positioning by the newly developed centering
element and Z axis slider enables highly reproducible measurements.

Motor cores, which are the base of motor assemblies, require highmachining accuracy. ROUNDTRACER EXTREME allows for efficient,high-precision workpiece setup for rectilinear contour measurement at
multiple points.

The rotating X-axis tracking measurement function enables all-roundmeasurement and assessment* of splines exceeding the measuring
range of the detector.

supporting measurements for a wide variety of
workpieces. It delivers efficient, high-precision
measurements, such as continuous
measurement of inside diameter and uppersurface of thick workpieces owing to themotorized sliding axis, or automatic recognitionof the stylus tip position during continuous
measurement of inside and outside diametersof small holes.
