WHAT IS A SKID?
The SR160 is a skidded device. The skid guides the pick-up along
the workpiece, with the workpiece itself forming the datum for
measurement. This method usually eases set-up by reducing the need
for leveling. It also reduces the effects of vibration due to a much smaller
measuring loop.
The skid is an integral part of the gauge and has a radius large enough
to prevent movement in and out the roughness characteristics of the
surface. The stylus and the skid are independent in their height (Z)
movement but move together in the measurement direction. Surface
deviations are recorded as the difference between the stylus and the
skid movement in the Z direction.
The skid will act as a mechanical filter, taking out much of the general
form of the component. Also, wavelengths greater than the diameter of
the skid will not register.
