DIAMONDS AREN’T ALWAYS FOREVER
When using my profilometer for bore and surface readings, I hold the drive on the workpiece until the stylus has retracted and recorded it’s reading. Then, I lift it off and let it retract without touching the workpiece. This effectively reduces the amount of contact time that the stylus sees by 50%. Your reader will stay in calibration for much longer, and the stylus diamond will have a longer life. I’ve never had a problem holding it in bores or on surfaces, because I have the drive body face covered in paint protectant film. It gives it some traction.
