Carbide Inserts Use scale
Commonly used carbide cutting tools use scale
YG alloy: mainly used for processing cast iron, nonferrous metals and non-metallic materials. Fine grain cemented carbide (such as YG3X, YG6X) in the cobalt content together with the grain in the hardness and wear resistance higher, for more Processing some special hard cast iron, austenitic stainless steel, heat-resistant alloy, titanium alloy, hard bronze and wear-resistant insulation materials.
YT alloy: the outstanding advantages are high hardness, good heat resistance, high temperature hardness and compressive strength than the YG high, good antioxidant function.Thus, when the knife requires a high heat resistance and wear resistance , Should use the higher grade of TiC grade.YT class alloy is suitable for processing plastic materials such as steel, but should not be processed titanium alloy, silicon aluminum alloy.
YW alloy: both YG, YT alloy function, induction function is good, it can be processed steel, but also for processing cast iron and nonferrous metals. Such alloys such as the addition of cobalt content, the strength can be high, can be used for a variety of Difficult processing of rough processing and intermittent cutting.
Carbide cutting tools in the production process to prevent the occurrence of cracks in four main areas:
1, knife row own doubt. The thickness of the knife below the blade can not be less than 1.5 times the thickness of the blade (preferably more than 2 times).
2, the welding should be blowing the blade (nor too much), copper water to the full flow to the welding surface (that is, can not have Weld).
3, after welding the cooling to be slow, the best use of sand after the knife to cover up the welding, 12 hours later.
4, grinding process do not water (can be used air-cooled), do not put the blade grinding too hot.
"Carbide tool common sense and use of the method" is a guide on the understanding of carbide tools, carbide, such as turning tools, cutter, drill, reamer and other shapes, uses, selection criteria and Use conditions and so on. The main contents include: the elements of the carbide tool, the type of carbide cutting tools, the basic knowledge of carbide cutting tools, tool damage and its countermeasures, as well as processing failures and solutions.
