Grinding disc of composite resin
The grinding discs of unistar composite resin are made of metal powder consisting mainly of copper, iron and tin in combination with composite resin. Ideal for use with diamond grinding fluids. The hardness and density of such discs is lower than that of metal copper, which contributes to the injection of diamond particles, consistently maintaining a high removal rate, without causing large scratches, abrasions will not be pressed into the processed material during processing.
Suitable for unilateral and bilateral precision grinding or rigid polishing of different materials.
