GRINDING WHEELS WITH CRYSTALBOND
The innovative grinding wheels manufactured by ANDRE ABRASIVE ARTICLES bonded with CRYSTALBOND are a group of products that are dedicated to demanding grinding operations.
Processing of hard-to-machine materials
Characteristics of glass-crystal bonding applications
The use of glass crystalline bond makes it possible to produce grinding wheels with unique technical features. Tools bonded with the innovative CRYSTALBOND can be used in operations requiring efficient grinding of hard-to-machine materials or components with very high hardness.
Used in various stationary machines.
Thanks to our experience, ANDRE's new glass-bonded tools are of high quality.
Applications of glass-crystal bonded grinding wheels:
Features of CRYSTALBOND grinding wheels:
high performance grinding process
high quality of the ground surface
high resistance to brittle fracture
high self-sharpening ability
Innovative formulation and modern technology
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.
