Saphir 375 Stone Grinder


The ATM Stone Grinder is a water cooled, high speed machine for quickly plane grinding samples in a specimen holder. The coarse grit grinding stone turns at 1700 rpm to plane grind a typical batch of samples in less than 30 seconds. Both mounted and unmounted specimens are easy work for this high speed machine.

The system is designed to give the operator total control of the parameters, including the diamond dressing tool's interval, depth and speed at which it dresses the stone. Grinding depth (Z-axis) is programmable allowing the operator to remove the desired amount of material for any sample batch to within 0.1 mm accuracy.
