S1.mostly using on the electrical tools and air tools drives(also can be machine tool), rotate speed is 6000-40000rds/m.the carbide burrs needbe correct clamped,cutting direction should be uniformly moving from right to left ,can't be to-and-fro motion.using the goggles to avoid to smear metal splashing.
2.can't increase too big pressure in the case of the grinding machine's speed is decreasing,if so,will cause the carbide buurs too hot and get dull easily..
3.the carbide burrs should be contacted with workpiece enoughly,then the more cutting edge can go deep in to the workpiece,and make the better effect .
4,should avoid the shank to contacting with workpiece,if so,the carbide burrs will be very hot and destroy the copper welding joint .
5.in operation,can use some lubricants ,like iquid wax lubricants and synthetic lubricants,can add some lubricant into carbide burrs head regularly.
