GrinderQ(1) It is desirable to use a specialized high rigidity grinder. (2) Wet grinding must be used.
AbrasivegrainDiamond
Grain sizeRough grinding: 400 mesh Finish grinding: 800 to 1,500 mesh
Griding WheelBondVitrified, or metal bond specialized for polycrystalline diamond tools
Concentration100 to 125
DressingDress with a stick that is approximately 400 mesh WA
Peripheral Speed800 to 1,000 m/min
Grinding conditionsTable Rocking30 to 60 rev/min
GrindingfluidWater soluble grinding fluid (solution type)
OtherQ(1) The rake surface 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 require a sharp cutting edge. (4) Surfaces that were cut by EDM should have more than 0.05mm ground off.
