discussion). Grinding, lapping, polishing, and CMP (chem.-mechanical polishing) are all techniques used for precise removal of material. A brief discussion of terms is needed to understand the basics of what is being referred to when these topics are discussed. 2.1: Grinding
Typical stock removal is usually .010 to .030. Production Lapping has lapped many types of mechanical pump bodies and the internal rotors. The lapping process for this type of part is now often times replaced with our fine grinding process. However, there are still applications that dictate the lapping process be used exclusively.

Mechanical pump bodies need to be held to very close tolerances usually in the +/- .0002 (.005mm) and parallel to .0001 (.0025mm). Typical stock removal is usually .010 to .030. This is easily achieved with Fine Grinding with cycle times around 3-5 minutes.
Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or by way of a machine.
3) Lapping is carried out at low speed and low pressure, so the heat generated is very small. There is no metamorphic layer on the surface of the workpiece, so the quality is better. 4) The structure of grinding device and grinding machine is relatively simple, which is suitable for both single piece manual production and batch mechanical ...
