Term Main definition
Sintered workpiece

Sintering is the process of compressing and shaping a solid mass of material by heat or pressure without melting it to the point of liquefaction. In this process powdery or granulated starting materials are first pressed into a mould and then compressed. A sintered workpiece is a workpiece produced using this process.


Superfinishing is a metalworking process that improves the surface quality and geometry of the workpiece. This is achieved by removing only the thin amorphous surface layer with a grindstone or grinding belt. Superfinishing unlike polishing which produces a high-gloss finish creates a crosshatch pattern on the workpiece. Other names for this are: short stroke honing microfinishing

Surface grinding

Surface grinding is a grinding process that produces a flat plane surface on the workpiece. The generic term surface grinding includes several processes such as honing superfinishing double-sided grinding and lapping.
