Applications

Measurable workpiece range: plane, cylindrical surface, cone, bore, groove, surface, etc. (special surface to be equipped with a sensor for measurement).


Working Principle

When measuring the surface roughness, the sensor slides along the straight line at a constant velocity along the measured surface. The stylus touches the measured surface to generate displacement. The data is collected by the filter. The DSP calculates the output and displays the measurement result.

Description

KS100 Standard Sensor

KS100 Standard Sensor, to measure most   of the plane, inclined plane, cone surface, inner hole, groove and other   surface roughness, in addition to the standard sensor, other special sensors   are needed to measure the measuring platform.

KS110 Curved Surface Sensor

KS110 Curved Surface Sensor, to measure smooth cylindrical surface which radius is larger than 3mm, for the large radius smooth spherical surface and other surface also can obtain good approximation, need to work with platform KA520 or KA620.

KS120 Small hole Sensor

KS120 Small hole Sensor, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform KA520 or KA620.

KS131 Deep Groove Sensor

KS131 Deep Groove Sensor, measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of step with height less than 10mm, also can used to measure the   planar, cylindrical used with platform,better to work with platform KA520 or   KA620.

KA520 Surface Roughness Measuring Platform

KA520 Surface Roughness Measuring Platform, adjustable height 200mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

KA620 Surface Roughness Measuring Platform

KA620 Surface Roughness Measuring Platform, adjustable height 300mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

Surface roughness standard template

Surface roughness standard template,Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than   metal roughness block.

Meet standard GB/T19067.1-2003 and   ISO5436-1:2000

Approximation: Ra=0.1um, 0.2um,   0.4um,  0.8um, 1.6um, 3.2um, 6.4um
