AN INNOVATIVE BOND OF A NEW GENERATION

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.

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.

Machining process: circumferential axial grinding of cylindrical internal surfaces.
Workpiece: inner surfaces of bearing rings made of 100Cr6 steel (63±2 HRC), inner diameter: dw = 40 mm, width: bw = 18 mm.
Grinder: RUP 28P.
Abrasive tool: type 1 flat grinding wheels of 35×10×10 mm.
Grinding parameters: - wheel peripheral speed ns = 27300 rpm,
- workpiece peripheral speed nw =400 rpm,
- grinding depth ae total = 0.20 mm,
- table axial feed rate: vfa=20mm/s.
- PCS: cooling lubricant - 5% aqueous solution of Castrol Syntilo RHS oil injected into the grinding zone by means of a flooding method.
