Precision cutting tools manufacturer Komet has installed Vollmer technology in its Stuttgart manufacturing plant to automatically polish PCD (polycrystalline diamond) blades.

The Komet group, which encompasses the Komet, Dihart and Jel brands, manufactures composite and PCD thread milling cutters and drilling tools.

Komet’s primary aim in selecting polished PCD cutters was to increase the lifespan of its milling tools when used on highly abrasive composite materials.

To answer this need, the company selected the universal QXD 200 machine, which automatically polishes PCD milling tools when they are eroded.

Key benefits of product application

  • Milling tools polished by the machine are less susceptible to wear
  • Polished PCD tools offer extended tool life when working with composite materials
  • Automatic polishing has eliminated the need for time-consuming manual polishing
  • The diamond grinding disc only polishes the PCD blades directly behind the bevel, facilitating shorter processing times and less wear on the polishing disc
  • A typical PCD face milling cutter eroded by the QXD 200 in approximately four-and-a-half hours can afterwards be fully polished within 30 minutes

The Vollmer Group specialises in the processing of tools in respect of both production and services. Its product range embraces the latest sharpening and eroding machines for saw blades and tools used in the metal and wood processing industries.

The Group's headquarters in Biberach, Germany, is the design and development centre for its products. Other production sites are located in Mörlenbach, Germany, and Taicang, China.

With 700 employees in nine branches and 30-plus agencies, the company works closely with customers at local level, thus ensuring the same high standard of consulting and customer care worldwide.
