Grinding Stone

The grinding stones are used for grinding/polishing the copper layer of the gravure cylinder.

Features:
Coarse grinding stone and finishing grinding stone.
Grinding stones in addition to an outstanding cutting performance when achieving fine roughness values.
Our particular synthetic material has been developed especially for the stones mass in order to assist in the defined continuous removal of worn out abrasive particles.
Spring-mounted abrasive wheels guarantee an even grinding pattern without chatter marks, score marks or other irregularities.

Specifications:
OD: 200mm
ID: 100mm, 50mm
TH: 50mm, 100mm
Grade: #180, #280, #320, #400, #600, #800, #1000, #1500, #2000, #2500, #3000
Special specification can be customized as per customer's requirement.

Yinglong also produce other typed grinding-wheels. Such as grinding-wheels to grind blades / cutters, milling cutters and so on. There are many types.

BFA brown fused alumina powder for Grinding stone
Brown aluminum oxide crystals is made of bauxite/anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000degrees.Abrasives tools made by brown fused alumina are suitable for metal with high tensile (like:steel, malleable iron, bronze etc).and suitable for grinding, polishing, blasting, precision casting etc.Brown aluminum oxide crystal is also used for refractory material. Brown aluminum oxide crystals with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.
