Modern machine tools offer auto inspection machines. These auto inspection machines are used for checking turned races of bearings checking three parameters, i.E., race width, race dia for o/r or track dia for l/r races and track dia for o/r or at a time. The inspection is carried out with the help of indicators with electrical signals known as hicators having least count of 10 microns, with tolerances setting knobs.
The special features of auto inspection machines are as follows: cycle time 2 second, plc controlled, automatic loading with hopper, etc.
