Overview	Overall, 30A of the most powerful, power, price, followed by 20A, again, is 40A; customers can choose according to their needs on different machines, in general, more complete on the functional requirements, choose 30A , just grinding cone knives, cutters, and recommended to choose 20A (20A function as strong, but with a difference of only 200 yuan price 40A or so)

Note



1. Whether the material grinding by the grinding tool decision, in general, Diamond wheel For grinding Carbide So hard the knife, while the General grinding wheel (such as corundum wheel) For grinding High-speed steel Tools and other materials.

2. Tool Finish Is also guaranteed by the grinding wheel, grinding wheel finer grinding tool or the workpiece out of the higher finish, but the finer the grinding wheel, grinding slower pace.
