It is the most common grinding operation and comprises over 75% of production grinding. Cylindrical grinding between centers brings parts to exact diameter, concentricity, and surface smoothness. Diameter tolerances in the tenths of thouhs of an inch are common. Precise tapers may also be applied.

· For the path velocities needed for grinding the range of possible path types is strictly limited. Possible rotational speeds are considerably higher for the ZL 700 built in 1998. Here, both grind,ing wheels can be driven with up to n,l = 2 435 min’, the .
Lapping is an advanced surface flattening process that achieves flatness tolerances of to inches. The pressure on the parts and the process duration can be finely tuned to accommodate the part material and the final finish required. Under perfect conditions, parts can be lapped to within 10 to 20 millionths of an inch of flatness.
Blade lapping and grinding. Perhaps the most critical piece in ensuring successful scraping (with a pleasing appearance) is that the cutting edges on the scraper are lapped to a very fine finish. For push scraping the edge can easily be formed with a resin bonded diamond wheel but all scratches must be removed by lapping with a rotary lap.

A typical range of surface roughness that can be obtained without resorting to special equipment would fall in the range of 1 to 30 units Ra (average roughness), usually microinches. Surface accuracy or flatness is usually measured in helium light bands (HLB), one HLB measuring about 280 nm ( × 10 −5 in).
