Fillers in Resin Bonds

Fillers in resin bonds have several tasks in both manufacturing phase and grinding operation: They induce porosity, reinforce bond properties, change aesthetics, and more [FRAC10]. Common fillers in resin bonded grinding tools are cryolite (Na3AlF6), pyrite (FeS2), zinc sulfide (ZnS), lithopone (ZnSBaSO4), potassium fluoroborate and potassium chloride (KAlF4, K3AlF6), potassium sulphate (K2SO4), and mixtures of […]


Lapping is a mainly room-bound process with geometrically undefined cutting edges. It is defined as a cutting process with loose grits distributed in a fluid or paste, so called lapping slurry, guided by a counterpart, which is usually shape-transferring (also called lapping tool). The cutting paths of the individual grits are ideally undirected [KLOC09, p. […]

Fiber Reinforced Resin

Asen [ASEN08] has patented a wheel body made from a fiber composite, specif­ically with carbon fibers, glass fibers, or synthetic fibers. Different fiber structures are undergoing investigation, in particular uni-directional, orthotroph (fibers in different orthogonal directions) or transversal-isotrop [KRAF08]. The fiber struc­ture affects body strength and isotropy. Vitrified and resin bonded abrasive layers are glued […]

Cutting Edge Density

Cutting edge density is important to understand tool performance during the grinding process. Many researchers analyzed the statistical nature of the cutting edges [KASS69, BUTT68, SALJ88, HOU03, LORT75, etc.]. 6.2.1 Definitions Static Cutting Edge Density Researchers differentiate between grit number and cutting edge number because each grit can have several cutting edges. However, both […]

Grinding Process Model Traditional Fundamental Requirements in Grinding Manufacturing processes have to accomplish certain tasks depending on workpiece material, stock removal (finishing or roughing operation), availability of machines, batch size, form and dimension tolerances, achieved surface roughness and integ­rity, and more [LINK12c]. The following discussions focus on ductile material in finishing operations and the choice of the […]
