Claims6
A polishing tool, comprising a working layer with comprises cerium dioxide abrasive particles and a synthetic resin binder, a body layer, and an intermediate layer located between the working layer and the body layer, wherein the body layer is harder than the working layer, and the intermediate layer is softer than the working layer, said intermediate layer having a hardness which is 3 to 4 times lower than a hardness of said working layer, said intermediate layer having a thickness which is 0.8 to 4 times a thickness of the working layer.
A polishing tool, comprising a working layer with comprises cerium dioxide abrasive particles and a synthetic resin binder, a body layer, and an intermediate layer located between the working layer and the body layer, wherein the body layer is harder than the working layer, and the intermediate layer is softer than the working layer, said intermediate layer having the following composition consisting of in part by weight:
- Hydrogenated Nitrile Elastomer 100 Vinyl Chloride 10-30 Magnesium Oxide 4-15 Zinc Oxide 4-15 Dibutilphtalate 5-20 Sulfur 1.5-4.
A polishing tool, comprising a working layer with comprises cerium dioxide abrasive particles and a synthetic resin binder, a body layer, and an intermediate layer located between the working layer and the body layer, wherein the body layer is harder than the working layer, and the intermediate layer is softer than the working layer, said working layer, said intermediate layer, and said body layer all include hydrogenated nitrile elastomer and being chemically connected with one another.
