8 Principles of Centerless Grinding

Dec 08, 2016· A 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.

back grinding process

The TAIKO process is the name of a wafer back grinding process that uses a new grinding method developed by DISCO. This method is different to conventional back grinding. When grinding the wafer, the TAIKO process leaves an edge (approximately 2 mm) on the outer most circumference of the wafer and thin grinds only the inner circumference.
