Flute/thread grinding with EHWA grinding wheels

In drill and milling cutter production, flute grinding is the key technology and the main cost factor.

EHWA has been developing special synthetic resin and vitrified bonds for years, which allow enormous feed rates and thus create a clear competitive advantage over other competitors.

The open-pored bond structures in particular stand out due to their grinding performance.

VC | EHWA vitrified bond

Case study | flute grinding | carbide:

  • Machine: ANCA FX7(19 KW)

  • Material : Hartmetall

  • Workpiece: Φ 12–50mm(LOF), 2 Spiralen (K10)

  • Feed rate: 120 mm/min

  • Cutting depth: 2.4 mm from the solid

 

Advantages | EHWA - Precision tools

  • High productivity with minimal tool costs

  • Significantly improved surface and edge quality

  • Very high edge stability of the tools

BG | EHWA synthetic resin bond

Case study | Circular saws / hobs / cutting tools | HSS and carbide:

  • Long lifetime of the grinding wheels
  • Grinding time reduction

  • Reach fine surfaces

  • High form and dimensional stability

EHWA Bonds for tool grinding

Resin Bond

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

HT – Polyimidbindung(PA): This polyimide bond is characterized by high surface quality on the workpiece

Phenolic resin bonds(BG)This bond form is particularly suitable for general grinding applications on HSS, ferrous/non-ferrous metals. It has good elasticity and free-cutting properties.

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.
