Grinding is a machining process during which every grain which comes into contact with the material rips a minute chip out of the material.
According toDIN 8580, this process is a cutting process.
Grinding is used for:
EFCO-GSS - Grinding Tools (CBN) |
|
The EFCO GSS grinding tools are coated with cubic crystalline boron nitride (CBN) of grain size B252 with galvanic bond. |
Lapping is a machining process to smooth surfaces.
An abrasive embedded in a lubricant is used for lapping. In contrast to grinding where the abrasive is anchored to the backing material lapping works with moving (rolling) grain.
DIN 8589 divides lapping into two groups:
Lapping plates / lapping spindles of grey iron are used for lapping. Lapping pastes can be applied to the sealing face or lapping plate / lapping spindle constantly as required. After lapping, sealing face and lapping palte must be degreased and cleaned to 100 %.
