Tool grinding with EHWA grinding wheels

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

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

These grinding wheels are designed for optimum productivity, taking into account the improved cycle times and dressing intervals. This results in very good grinding performance with consistent quality and very low edge chipping of the indexable inserts.

EHWA Bonds for tool grinding

Resin Bond

Polyimidbindungen(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 synthetic resin bond. This combines the advantages of both materials - high wear and dimensional stability and good grinding performance

Ceramic bond

Highly porous vitrified bonds(VDGF, VHGN)This bond achieves a long lifetime with a high grain concentration. Due to its porous structure, this bond also has a high grinding performance. Very suitable for grinding PCD, PCBN, ceramic and metal.

Metal bond

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