Tool grinding with EHWA grinding wheels

EHWA provides a complete range of grinding tools for machining carbide, ceramic, cermet and PCD/PKBN inserts. We offer highly efficient bonds developed from years of cooperation with the world's leading manufacturers of inserts.

EHWA grinding wheels are now in use worldwide for the following machine manufacturers: Agathon, Wendt, Waida, EWAG, Farman, Corbon, Easy grinder, Ewamatic etc.

These grinding wheels are designed for optimal productivity, considering the improved cycle times as well as dressing intervals. This is shown in a very good grinding performance with consistent quality and a very low chipping of the inserts.

EHWA bonds for tool grinding

Resin bond

Polyimide bonds(BXT, SA): The high thermal resistance is ideal for grinding at high speeds.

Phenolic resin bonds(BG): This bond form is particularly suitable for general grinding applications on HSS, ferrous / non-ferrous metals.

Hybrid bonds(RM, BMX): The combination of metal and resin bond. This combines the advantages of both materials-high wear and shape resistance and good grinding performance.

Ceramic bond

High porosity ceramic bonds(VDGF, VHGN): At high grain concentration, this bond reaches a high lifetime. Additionally, this bond has a high grinding performance due to the porous structure. Very suitable for grinding PCD, PCBN, ceramics and metal.

Metal bond

Metal bonds(MFS, MX): High wear resistance and high dimensional stability.
