Q: Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?: Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q: What does WC refer to in cemented carbides?: Refers to: tungsten carbide powder, is the main raw material for the production of cemented carbide, chemical formula WC. Full name: tungsten carbide powder is black, six square crystal, has metallic luster, hardness is similar to diamond, it is good conductor of electricity and heat.

Q: What is the difference between hard alloy and steel: Cobalt (Co) is used in bonding in the alloy, is in the process of sintering, it can make the tungsten carbide (WC) powder and tightly surrounded Bonded together, after cooling, became hard alloy. (equivalent to the cement content). Usually: 3%--30% tungsten carbide (WC) is the main component of some metal properties of the hard alloy or cermet, the total composition of 70%---97% (weight ratio) is widely used in wear-resistant, high temperature resistance, resistance corrosion, bad working environment of the parts or tool, cutter tools.

Q: What kind of carbide alloy is used in stainless steel processing?: Machine tool steel. Better cooling, liquid viscosity and sulfur chosen for good cooling performance, the pressure of the cooling liquid chlorine.

Q: Machining center 8 mm carbide cutter processing 45 steel, how to set the speed, feed, and moving speed?: if the speed in the three thousand, each Z axis 0.3 wire feed, can be a little faster, must spiral knife Oh, this is not a knife eat 5 mm. I found a 55 degree flat cutting parameters of tungsten steel milling table

Q: Is there any pollution in the production of cemented carbide?: The chosen of mask filter is good, also want to close modified ah buy mask anti fog and haze, one can see the standard, can be seen in the two to see that the filtration efficiency standards, should be the most familiar N90, N95 series of mask 3X brand, which is based on NIOSH standard name. In addition to the NIOSH standard, common and ASTM ASTM standard, China standard KN and the European FFP standards, can be used to measure an important indicator of masks, medical masks ordinary cheap, protective also poor, it is only suitable for ordinary nurses or at home cooking; and senior medical masks are surgery the doctor or dentist, the doctor does not care about the higher income, cost is low and the mask, pay more attention to the quality of respirator. The high grade medical mask has excellent barrier to particles and fluids, and ensures breathability and breathability in a precise working environment. Can deodorant ah, city toxic particles source: the first is the automobile exhaust the United States imported medical masks Hiroe server Hin, filter, not only anti particles but also prevent droplets. The particles as small as 0.1 micron filtration efficiency up to 99.8% of bacteria or virus vector as small as 0.3 microns (common in droplet) filtration efficiency is up to 99.9%. Using SecureFit patented technology, through adjustment to adapt to different facial shapes, to achieve high consistency, for your health and family, go out wearing masks, in the J good style East, I wish you happiness, hope to adopt

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.

Q: What is the hardness of the carbide thread?: The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.

Q: Printing requirements for cemented carbide: Since 80s the advent of nano cemented carbide, and gradually formed a new sintering method, such as microwave sintering, field assisted sintering (such as spark plasma sintering and plasma activated sintering), two stage sintering, selective laser sintering etc..Vacuum sintering (Vacuum Sintering) is one of the more widely used methods for cemented carbide sintering, which began in the 30s of last century,Great progress has been made in the past thirty years. Vacuum sintering is the process of sintering and pressing in a negative pressure gas medium. Vacuum sintering can improve the purity of furnace gas and the negative pressure can improve wettability of bonded hard phase. Vacuum sintering has the following advantages: sintering in vacuum condition, hinder greatly reduces the adsorption of gas on the surface of powder and closed pore gas on the densification of the powder, is favorable to the diffusion process, which is conducive to the densification; better able to exclude Si, Mg and Ca in the sintered body trace of oxide impurities thus, to improve the purity of hard alloy; improve the wettability of liquid phase sintering, is conducive to tissue shrinkage and improve the alloy.

Q: What are hard alloys? Which ones are they? How often are they chosen?: It is based on one or several carbides (TiC and WC) as the hardening phase, with carbon steel or alloy steel (such as high-speed steel, chrome molybdenum steel) powder as binder, powder metallurgy materials through proportioning, mixing, pressing and sintering. After annealing, it can be machined. After quenching and tempering, it has the same hardness and high wear resistance as the hard alloy. It can also be forged and welded, and has the characteristics of heat resistance, corrosion resistance and oxidation resistance. The utility model is suitable for manufacturing various tools with complicated shapes, such as twist drills, milling cutters, etc., and can also manufacture moulds and wear-resistant parts which work at higher temperature.
