PARAMETER FOR DIAMOND AND CBN GRINDING WHEEL

————————————————————————————————————————————

BOND MODIFICATIONS

————————————————————————————————————————————

KA	Good elasticity. Depth of grinding is about 0.01 mm. Mainly used in micron size abrasive and grinding of cemented carbide, hardened steel and PCD. (Polycrystalline Diamond)
KB	Heat transfer is excellent for dry grinding. Especially effective for CBN Wheels. Mainly used in cup type wheel.
KC	Heat transfer and shape maintenance are very good. Applied to flute grinding of endmill, reamer and drill (HSS)
KD	Very soft. Low noise and good finished shape. Used in general grinding of cemented carbide.
KE	Used in heavy duty dry grinding with diamond cup type wheel.
KG	Standard bond for all kinds of workpieces. Applied to profiled, face and centerless grinding.
KH	Shape maintenance and heat transfer are very good. Applied to profile and face grinding.
KN	Same applications as KB, but harder.
KP	Lubricant bond. Same applications as KG, but softer.
KX	Good cutting ability. Applied to flute grinding of endmill, reamer and cemented carbide by down feed method.
