Grinding Tools

Grinding wheels for steel and non-ferrous metals

The variety of grinding processes requires a wide range of wheel types. Originally developed for the high demands of in-house production of diamond dressing tools, DR. KAISER today offers a wide range of grinding wheels.

The CBN and diamond grinding wheels are manufactured in vitrified, electroplated, hybrid, resin or metal bonds.

CBN grinding wheels

Produced by synthesis: The covalent bonding of boron and nitrogen, CBN is the second hardest material with a hardness of approximately HV 4500. The high thermal and chemical stability of CBN permits the machining of steel materials and results in high cutting performance during the grinding process. In order to utilize the full potential of CBN, it is essential to use with high cutting speeds. The large number of different CBN types leads to an adaptation of grinding tools to suit the wide variety of applications. Steels, Ni-based alloys or HSS: CBN is the right abrasive here.

Diamond grinding wheels

Carbon in covalent bonding is the hardest material and has a hardness of HV 9000. New production techniques with synthetic diamonds allow the production of grits optimized for the application. In this way block-shaped or splintered variants can be used to adapt grinding tools to the process. Diamond oxidizes in air to form carbon dioxide at temperatures of approx. 700°C. These temperatures occur in many machining applications for ferrous materials and lead to a rapid decomposition of diamonds due to the affinity between Fe and C. Diamond is the right choice for carbide, cermets, ceramics, PCD / PCBN, thermal sprayed alloys, sapphire, glass, silicon, ferrite, graphite or composites.
