How To Use Carbide Burrs
Definition of carbide burrs. Cemented carbide rotary burrs are made of carbide (WC, TiC) micron powder with high hardness and refractory metal as the main component, cobalt (Co) or nickel (Ni) or molybdenum (Mo) as the binder, powder metallurgy products sintered in a vacuum or hydrogen recovery furnace. IV B, V B, VI B group of metal carbide, nitride, boride, etc., because the hardness and melting point are particularly high, collectively known as cemented carbide. To teach you the principles of choice Selection of section shape of cemented carbide rotary burrs The section shape of cemented carbide rotary burrs should be selected according to the shape of the part to be rasped so that the two shapes are suitable. When filing inside the arc surface, choose the half-round file or round file (small diameter workpiece). When filing inside the angled surface, choose the triangle file. When filing inside right angle surface, choose a flat-file or square file, etc. When using a flat file to cut the right-angle surface, care should be taken to make the narrow surface (smooth edge) without teeth near the right-angle surface, so as to avoid hitting the right-angle surface.
