circumference speed in m/sec

Economic Cutting Speeds (Average)

grinding approx. 30 m/sec -10% +20%
deburring dry approx. 15 m/sec ± 10%
deburring wet approx. 25 m/sec ± 10%
polishing of metals approx. 36 m/sec ± 15%
polishing of metals with pronounced contours (sanitary fitting) approx. 15-25 m/sec ± 10%
synthetic materials, varnishes and wood approx. 15 m/sec ± 10%

The higher the number of revolutions per minute of a polishing tool the harder and the less flexible will be the tool’s surface. Excessive pressure and too high speed of the tool on the work piece will lead to burning of both work piece and tool.
