A numerical control car tool, what materials are used in the car
This depends on your experience in the factory practice. Tool use need to be flexible! And there are dozens of them. The processing form of the workpiece is changed again. It's up to you to get through it! I probably say a few commonly used! The machete of a car is usually made of a T9015 plate with a titanium plate. The intensity is relatively large, also can fine car, but the workpiece size that the precision is too high is not too good, the finish is between 1.6-0.8! The auto steel parts are usually made of the ceramic head of NS530, there are two kinds, the market is usually with the cutting slot, the strength is small, the processing allowance can't be too much, the smooth finish can reach 0.8
The other kind of without cutting slot, the market is not too much, the order is usually required, the tip of the blade is slightly tilted, and more than 0.8. Car non-ferrous metal, copper, aluminum, easy cutting steel, diamond knife, smooth finish to 0.4 car quench workpiece, with the cubic nitride taut tool head. Stainless steel and cast iron also have their own head, not too much, don't remember the number! These are really good choices. You just buy a knife and make it clear to the cutter that they will choose the tool for you. But don't buy domestic knives. You don't usually specify a tool brand. They will give you the head of zhuzhou and the English tools of chongqing. Because the knife is profitable! Also, the tool must use R0.4 and R0.2. The cutter will sell you 0.6. Because they can't sell it!
Synthetic diamond Diamond is not stable state of the carbon thermal oxidation and graphitization, the killing must be maintained for forced cooling, the unfavorable processing of iron group elements, because the diamond of carbon atoms and the affinity of iron, low tool life. I was looking for the materials in the textbook from the mechanical manufacturing technology foundation of the mechanical engineering press. Because I don't have too much contact, I dare not recommend it. I hope my answer will help you.
High speed steel HSS is high alloy tool steel with more tungsten, molybdenum, chromium, barium and other alloy elements. Its high strength, bending strength is generally 2-3 times of carbide, ceramic of 5-6 times), good toughness and can be applied in places that have requirements of shock, vibration, and is often used for machining non-ferrous metals, steel, cast iron, high temperature alloys and other materials. In addition, high performance high speed steel can be used for cutting all kinds of difficult machining materials, especially suitable for making all kinds of precise cutting tools and complicated cutting tools. Hard alloy carbide is a powder metallurgical product which is sintered with high hardness, refractory metal carbide and metal binder in high temperature conditions. It falls into three categories: P, K, and M. The concrete table: 3, ceramic ceramics mainly has alumina ceramic and nitride silicate ceramics. Resistance mo a1umna-based ceramic sex good, good heat resistance, high chemical stability, strong ability to resist adhesive, but the bending strength and toughness is poor, it is mainly used for finishing and semi-finishing chilled cast iron, hardened steel; Nitride ceramic is suitable for machining cast iron and high temperature to make me, the cutting steel material effect is not significant. 4, cubic boron nitride The hardness up to 800 hv, its can with common hard alloy cutting cast iron and steel cutting speed of chilled cast iron, hardened steel, high temperature alloy for processing, etc
