Solve the problem of titanium machining from the blade

The blade groove wear that occurs during the processing of titanium alloys is the local wear of the back and front in the direction of the cutting depth, which is often caused by the hardened layer left by the previous processing. The chemical reaction and diffusion of the tool and the workpiece material at a processing temperature exceeding 800 ° C is also one of the causes of groove wear. Because during the processing, the titanium molecules of the workpiece gather in the front area of the blade and "weld" to the blade at high pressure and high temperature to form a built-up edge. When the built-up edge is peeled off from the blade, the cemented carbide coating of the blade is carried away, so titanium alloy processing requires special blade material and geometry.
