Mahr’s new option package for its
MarForm MMQ 200 FormTester
provides for the measurement of
surface finish parameters according
to accepted ISO, ASME and JIS
standards. The combined
hardware/software MMQ 200 Surface
Finish option reduces set-up and
measurement cycle time, while
cutting the overall cost of both form
and surface measurement, as only a
single piece of equipment is required.

“The key to providing accurate
surface finish data with a form
machine is high resolution and low
residual noise,” says Brett Green,MD,
Mahr UK.”Unlike many form
measurement machines that have
been designed to measure longer
wavelengths and allow 5-10 microns
between data points, the control
system of the MMQ 200 has been
designed with roughness
measurement in mind. It can sample
data with spacing down to 0.5
micron, which is well within
accepted international standards for
roughness measurements.”
