One of the fundamental data of the lapping is the use of these abrasives in a chemical environment (carrier), liquid or paste, to keep the abrasive particles free. This abrasive carrier is injected between the part and the lapping plate.
The " free abrasive " lapping process allows you to obtain two decisive criteria for the machined parts :
- The surface finish of the machined face is produced, precisely and constantly,
- An extreme flatness, the geometry of the part is directly led by the geometry of the lapping plate.
To guarantee the 2 criteria roughness and flatness :
- According to the part to be machined, you have a choice of an abrasive, abrasive carrier and lapping plate.
- The part must not be exposed to any thermal or mechanical tensions during the machining.
