Tungsten Carbide Cutter Wear

Tungsten carbide cutter wear and tungsten carbide tools similar basic laws, cutting thickness than conventional high-speed steel cutter is small, especially when milling, extrusion teeth on the product surface, glide more serious, so milling blade wear occurs mainly in the back. When tungsten carbide face milling cutter steel, because of high cutting speed, chip along the front of the sliding speed large, so when worn behind the front also has a smaller cutter wear. When carbide for high-speed intermittent cutting face mills, make teeth experiencing repeated mechanical impact and thermal shock, caused by fatigue cracks damaged teeth. The higher the speed milling, milling wear occurs sooner and more serious. Most tungsten carbide face mills because of fatigue damage and thus lose the cutting ability. If the cutter geometry selection unreasonable or improper use, tooth strength is poor, big teeth withstand impact, it will produce no cracks cutter wear.
