8 Principles of Centerless Grinding

Dec 08, 2016A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.

Metallographic Abrasive Grinding

For example, a 120 grit particle is approxmiately 105 microns in size, whereas, a 1200 grit particle has a particle size of 2.5 microns. The difference between the European P-grading system (number has a P in front of the number) and the more common ANSI or CAMI standard is that the European number is based on the number of openings if the width of the wire mesh was eliminated from the calculation.
