■ PCD (SUMIDIA) Grinding Method Functions
Description
V
Grinding Machine
(1) A special-purpose high-rigidity grinding machine. (2) Capable of wet grinding operations.
Q
Abrasive Grain Diamond Grain Size Rough Grinding: 400 mesh, Finish Grinding: 800 to 1,500 mesh Bond Vitrified or Metal Bond Dedicated for Polycrystalline Diamond Tool Concentration 100 to 125 Dressing Use a WA stick with a mesh of about 400.

Grinding Conditions
Table Rocking 30 to 60 cycle/min Grinding Fluid Water-soluble Grinding Fluid (Solution Type)
(1) The rake face is generally lapped. (2) Inspect for edge chipping using a microscope with a magnification of 30 to 50 times. (3) Machining of non-ferrous metals requires a sharp cutting edge. (4) Surfaces that were cut by EDM should have more than 0.002" ground off.
