SUPERHARD ABRASIVE TOOLS
Bonds - resin, ceramic or electroplated
SUPERHARD abrasive tools with diamond and cubic boron nitride (CBN) grains find their special use in precision grinding of
hard and hard-to-machine materials. The specificity of SUPERHARD results from both the high hardness of diamond and boron nitride and the bond used.
The characteristics of the binder used determine the properties of the tools, including their performance, ability to hold shape or influence the quality of the machined surface.
Resin bonds are characterized by efficient, cool and gentle grinding while removing as much material as possible. The ceramic bond increases the efficiency of grinding wheels - because, due to their structure, they better transfer coolant to the point of contact between the grinding wheel and the workpiece, and disperse the grinding residue. The electroplating bond allows for strong bonding while providing high exposure of abrasive grains. Grinding wheels with this bond are ideal for grinding with large allowances and where complex shapes are required (profile grinding wheels).
SUPERHARD, although they are a new proposition from ANDRE, are of high quality and safety in accordance with EN 13236 thanks to our many years of experience in the production of professional abrasive tools.
Our team of technology specialists responds to the individual needs of end users by manufacturing special application abrasive tools with strictly designed physical and mechanical parameters dedicated to specific grinding operations.

Top quality raw materials
At ANDRE ABRASIVE ARTICLES, modern hard abrasives are used in the production of SUPERHARD abrasive tools. Diamond and cubic boron nitride (CBN) grains are the hardest abrasives available and have a much higher hardness compared to traditional abrasives such as electro-corundum or silicon carbide. The hardness of cubic boron nitride is slightly lower than diamond however, due to its high chemical and thermal resistance, CBN is used for machining iron-containing materials.
D - Diament, (usually synthetic diamond)
B - Borazon, CBN, cBN
(regular boron nitride)
Abrasive tools by ANDRE ABRASIVE ARTICLES are safe.
ANDRE is successively improving its technological process to offer abrasive tools that provide increasingly better utility values and a high safety factor, in accordance with current standards, for superhard tools, among others, EN 13236 - Safety requirements for superhard abrasive tools. Membership in organizations of leading abrasive tool manufacturers and regular certification fully confirm that.
