In-process gauging instruments for controlling grinding machines:
Model PKP7

The model PKP7 instrument is intended to be used for introducing into the grinders corrective adjustments after gauging the machined external diameter of several components (e.g. piston pins) that come in succession out of the grinding area.

Due to their own weight the components move on an inclined prism of the gauging position. The method of gauging the external diameter is differential and is accomplished by two leak-proof inductive transducers with carbide spherical measuring tipsиндуктивных.

A command for a corrective adjustment can be developed after statistically processing the measured results.
