Grain types for grinding and honing tools
Application Properties Grain size
Grinding carbides and hard, brittle materials, e.g. face machining Uncoated diamond, angular, blocky grain shape, high thermal conductivity, chemically inert to non-ferrous metals D1 – D252
Grinding carbide materials, ceramics, cermet, glass, and ferrites Nickel-coated diamond, very good bond retention, versatile D46 – D252
Applications with constant power demand Globular shape, uniform quality, high strength D46 – D252
Grinding high-alloy and hardened steels Globular grain shape, high strength, ideal for wet grinding B54 – B252
Grinding hardened steel under high loads Globular or angular, suited to wet and dry grinding B46 – B252
Lapping and polishing hard materials Fine grain sizes, globular or angular, ideal for precision wet grinding G45, G30, G15

EHWA grinding wheel bonds

Resin bond

EHWA range: BA, BB, BC, BCT, BD, BE, BG, BH, BP, BQ, PAE, PA8

Composition: phenolic resins or polyimide bonds + abrasive grain

Benefits and properties: very high cutting performance, low grinding forces, flexible bond absorbs vibration well, very cost-effective, dressing possible only in exceptional cases

Application areas: tool grinding – high-speed steel, carbide

Ceramic bond

EHWA range: VB, VBT, VBTM, VE, VA, VD, VCL, VH

Composition: sintering process

Benefits and properties: excellent dressability (brittle bond, use rotating dressing rollers where possible), high form stability, high wear resistance, open or closed structure possible

Application areas: tool grinding – carbide, PCD, PCBN · bearing grinding – high-alloy steel grades · crankshaft grinding – high-alloy steel grades

Metal bond

EHWA range: MB, MC, MA, MF, MFS, MP, ME, MG, MX

Composition: sintering process (metal powder, mostly bronze-based, + abrasive grain)

Benefits and properties: high form stability, very high thermal conductivity, very high wear resistance, dressed via EDM

Application areas: edge grinding – glass types · profile grinding – glass and quartz · cutting – glass, ceramics, and stone · face grinding – optical lenses

Hybrid bond

EHWA range: BX, BXT, BXC, BMX

Composition: metal + resin

Benefits and properties: easier to dress than resin or metal bond, high removal rate, high edge stability, self-sharpening effect possible

Application areas: tool grinding – high-speed steel, carbide grades

Electroplated bond

Composition: nickel + abrasive grain, single-layer or multi-layer possible

Benefits and properties: recoating possible, complex profiles possible, high grinding performance, high tool life, not dressable

Application areas: bearing grinding – high-alloy steel grades · materials: nickel-based superalloys, non-ferrous metals, glass
