The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

3. Compared with the grinding speed, the circumferential speed of the honing head is not high (VC =16~60m/min). However, due to the large contact area between the honing band and the workpiece and the relatively high reciprocating speed (VA =8~20m/min), the honing efficiency is still relatively high.

RPM while the 1.2 L plenum results in a peak of 48.5 Nm at 9500 RPM. This is because runner length is the primary factor in determining the frequency (driven by engine RPM) for resonant supercharging [3]. Later in this paper, the effects of plenum size on engine performance operating at 9500 RPM will be more closely examined.

turns this universal cylindrical grinder into an effective internal grinding machine with high torque over a wide speed range. The machine can now grind with speeds up to 120,000 RPM, thus allowing the grinding of bores down to 0.625 inches (16 mm). A "flat" torque curve on this type of spindle means fewer spindles over a larger speed range.
