What type of car can be made of the car with a smooth surface
Quenching? It can be made with a common alloy blade.I hope my answer will help you.
No. 45 will use the alloy knife of its own. This kind of knife speed cannot be too high, too high can burn a knife. If the workpiece is not too large, it can also be done with the type of high speed that the blade can be used for the tool's performance.
The normal T15 is OK, mainly the Angle of grinding knife and the surface finish of the blade
