The use of commonly used carbide cutting tool size

YG-type alloys: mainly used for processing cast iron, nonferrous metals and non-metallic materials.Fine-grain cemented carbide (such as YG3X, YG6X) in the cobalt content with the ratio of grain hardness and wear resistance, apply more Processing of some special hard cast iron, austenitic stainless steel, heat-resistant alloys, titanium, hard bronze and wear-resistant insulation materials.

YT-type alloys: outstanding advantages of high hardness, good heat resistance, high temperature hardness and compressive strength than the YG class, anti-oxidation function is good.Therefore, when the requirements of the tool has a high heat resistance and wear resistance , Should be selected TiC content of higher grades.YT alloy suitable for processing plastic materials such as steel, but not processing titanium alloy, silicon aluminum alloy.

YW-type alloy: YG, YT-type alloys, both functional and general, it can be processed steel, can be used for processing cast iron and nonferrous metals. Such alloys such as cobalt content, the intensity can be used for a variety of Rough machining and interrupted cutting of difficult to machine materials.

Carbide cutting tools in the production process to prevent the occurrence of cracks there are four main areas:
1, the knife row itself in doubt. The blade thickness below the blade can not be less than 1.5 times the blade thickness (preferably greater than 2 times).
2, the welding blade should be thoroughly baked (not too much), copper water to flow to the surface of the full (that is, can not have Weld).
3, the cooling after welding to slow, the best use of sand after welding to cover up the knife row, 12 hours later.
4, grinding process, do not water-cooled (you can use air-cooled), not the blade grinding too hot.
