A new generation bond is the future of grinding processes

A new, user-friendly solution for ANDRE grinding wheels

ANDRE has developed a new ceramic binder with excellent operating properties.
Glass-crystal bonded grinding wheels ensure:
- higher efficiency of the grinding process,
- better surface quality,
- high self-sharpening ability
Grinding wheels with this type of bond are especially recommended for machining difficult-to-machine materials in the automotive, machine and aviation industries.

Results speak all...

During comprehensive research work aimed at composing the physico-chemical formulation of an innovative bond, ANDRE ABRASIVE ARTICLES, with the participation of specialists from scientific centers, developed and then implemented the technology of a completely new generation of glass-crystalline binding agents. This bond has specific properties, including, of particular importance, higher mechanical strength compared to conventional ceramic bonds.
