3. Use a high spindle speed Ceramic requires a high spindle speed to achieve a good surface finish. A high spindle speed ensures the tool moves faster along the surface, reducing the amount of contact time with the workpiece. This reduces the amount of heat generated during machining, which can result in cracking or chipping.
