Honing (metalworking) Wikipedia

Therefore, a grinding machine must be very stiff and its axes must move with very high precision. A honing machine is relatively accurate and perfect. Instead of relying on the accuracy of the machine tool, it relies on the averaging effect between the stone and the workpiece. Compliance is a requirement of a honing machine that is necessary for the averaging effect to occur. This leads to an
