Hard Coating On Welded Carbide Tool

Hard coating on welded carbide tool

When CVD coating is used, the cutting edge needs to be passivated in advance (the radius of the blunt circle is generally 0.02~0.08mm, and the cutting edge strength increases with the radius of the blunt circle), so the cutting edge is not sharp as the uncoated blade. Therefore, PVD method should be used for cutting tools with thin chips and sharp cutting edges. The coating can be coated in addition to ordinary cutting blades, but also coated to the integral tool, which has been developed to be coated in welded carbide tool. It is reported that a foreign company has adopted PCVD method on welded cemented carbide drill bits, and the result makes the service life of drill bits 10 times longer than that of HSS drill bits, and the efficiency increases 5 times.
