Where a grinding pad is used on a revolving platen, it will always wear unevenly due to the difference in relative movement speed and pad area across the pad diameter, this means that the grinding effect on the sample will change during the process, reducing the accuracy of the sample and the uniformity. Lapping is a more gentle process as the ...

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
Grinding is a type of abrasive machining process which uses grinding wheel as cutting tool.. A wide variety of machines are used for grinding, best classified as portable or staionary: Portable power tools such as angle grinders, die grinders and cut-off saws; Stationary power tools such as bench grinders and cut-off saws; Stationary hydro-or hand-powered sharpening stones
Surface grinding is often used to achieve parallelism and squareness in cubic parts or to make the two ends of a metal rod perpendicular to the rod's outside diameter. As an alternative when turning or milling is simply not precise enough, surface grinding can achieve micron-level tolerances and surface finishes down to Ra 8 µin (0.20 µm).

These discs can be used on lapping machines with rigid, flat support plates and with a lubricant to prolong disc life. They can be used for flat lapping, ceramics, metallurgical testing, sharpening carbide tools, gem faceting and grinding glassy materials that generate erosive swarf.
Lapping pastes are used for controlled removal and are used for the close mating of surfaces and for removing rust and the brightening of a metal surface. They are used for lapping of the exhaust and the inlet valves of engines, seat repairs of globe valves, the overhaul of reciprocating compressor valves, etc.
Surface grinding services can also be used on rods, although not to make the outside diameter of a rod round; for that task, OD grinding (also known as cylindrical grinding) is used. However, surface grinding can make the two ends of a rod perfectly perpendicular to the outside diameter. Here, V-blocks are used to position rods for grinding.

What is a Lapping Machine? Define Lapping: The term "lapping" is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.
