Assessing a single measurement result under two different evaluation conditions
A single measurement enables simultaneous analysis under two
different evaluation conditions. A single measurement allows calculationof parameters and analysis of filtered profiles without the need forrecalculation after saving data, contributing to higher work efficiency.

3-axis Adjustment Table <Option> 178-182
This table helps make the alignment adjustments required when measuring cylindrical surfaces. The corrections for the pitch angle and the swivel angle
are determined from a preliminary measurement and the Digimatic micrometers are adjusted accordingly. A flat-surfaced workpiece can also be leveledwith this table.

Auto-set
The auto-set function safely controls descent of the detector, eliminating
the possibility of operator error causing damage to the stylus.

Higher accuracy measurements with selectable drive unit

Extending measurement to narrow features

A wide range, high-resolution detector

Surface roughness measurement requires a run-up distance before starting
the measurement (or retrieving data). When the SJ-410 Series measures,its run-up distance is normally set to 0.5 mm. However, this distance canbe shortened to 0.15 mm using the narrow-part measurement function.
This function extends the measurement of narrow locations to features
such as piston-ring grooves and O-ring grooves.

Easily measures R-surface roughness (skidless measurement)
Usually, a spherical or cylindrical surface (R-surface) cannot be evaluated, but, by removing
the radius with a filter, R-surface data is processed as if taken from a flat surface.
Other curved surfaces can be processed besides cylindrical, such as parabolical and ellipsoidal.

Memory card (optional) is supported

The external device interfaces that come as standard include USB,
RS-232C, SPC output and foot switch I/F.

The measurement conditions and data can be stored in a memory card
(optional) and recalled as required. This enables batch analysis andprintout of data after on-site measurement.

Your choice of skidless or skidded measurement
Skidless measurement

Skidded measurement

Skidless measurement is where surface features are measured relative
to the drive unit reference surface. This measures waviness and finely
stepped features accurately, in addition to surface roughnness, but range
is limited to the stylus travel available.

In skidded measurements, surface features are measured with reference
to a skid following close behind the stylus. This cannot measure wavinessand stepped features exactly but the range of movement within whichmeasurement can be made is greater because the skid tracks theTraverse direction
workpiece surface contour.

Applicable standards

An “GO/ NG” judgment symbol is displayed when limits are set for
the roughness parameter. In case of “NG,” the calculated result ishighlighted. The calculated result can also be printed out.

Complies with many industry standards
The Surftest SJ-410 complies with the following standards:
JIS (JIS-B0601-2001, JIS-B0601-1994, JIS B0601-1982), VDA, ISO-1997,
and ANSI.

The “OK” symbol means the measurement iswithin the limits set; “NG” means it is not, inwhich case an arrow points to either the upper orlower limit in the printout.

Since it is 35 mm from the base top, a block of suitable height is required for calibration witha roughness specimen. Use the stand in combination with optional accessories such as aleveling table (178-016) or an XY leveling table (178-024).
