Abrasive grain Diamond Grain size Rough grinding: 400 mesh Finish grinding: 800 to 1,500 mesh Griding Bond Vitrified, or metal bond specialized for polycrystalline diamond tools Wheel Concentration 100 to 125 Dressing Dress with a stick that is approximately 400 mesh WA Peripheral Speed 800 to 1,000 m/min Grinding Table Rocking 30 to 60 rev/min conditions Grinding fluid Water soluble grinding fluid (solution type) M (1) The rake surface is generally lapped. Other Q (2) Inspect for edge chipping using a microscope with a magnification of 30 to 50 times. (3) Machining of non-ferrous metals require a sharp cutting edge. SUMIDIA (4) Surfaces that were cut by EDM should have more than 0.05mm ground off. Note: Contact us for re-grinding NPD10. SUMIDIA SUMIDIA Binderless SUMICRYSTAL M3
