Home Technology What is a Lapping Machine 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.
Chapter 4 Grinding, Reaming, Broaching amp Lapping In the republic of mediocrity, genius is dangerous. Robert G. Ingersoll Introduction Although grinding, reaming, broaching, and lapping remove a relatively small metal volume compared with turning and milling, they are important processes because they are often the last machining operation and determine final size and finish.
The lapping process involves passing a part between one or two large flat-lap plates or platens in a carrier fluid that contains an abrasive. The lapping process is more gentle than both superfinishing and honing and removes much less of the surface material. With lapping, Duval has the ability to produce a super-flat, polished surface.
Dec 23, 2018 Grinding machine is a type of machine tool and it is similar to other machine tools such as milling machine, turning machine, Lathe Machine and many more.

Surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.
Flexibility in speed control allows the instrument to be used as a grinding machine, high quality lapping machine, or polishing machine. During grinding high speeds are required, whereas lapping and polishing applications are generally completed at low speeds. The Model 920 also incorporates workstations, which allow for the use of
May 15, 2017 Lapping is a follow up process after grinding and used for create high accurate finish surface. This process is similar to grinding except it uses loose abrasive particle to remove instead of bonded material like grinding wheel.
In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. So when we start the electric motor the motor rotates at a certain rpm 150-15000 RPM, it may change according to the types of grinding machine with the help of v-belt and cone pulley the grinding wheel also starts rotating and we perform the operation.
