- Q: The difference between carbide knife and white steel knife
- 5, the scope of application is not the same: the general tool materials used carbide, complex difficult to shape, or require very sharp, high toughness and other field applicable high-speed steel
- Q: What is called cemented carbide?
- In addition to carbon atoms, a nitrogen atom and void boron atoms can enter the metal lattice, formed interstitial solid solution. With the properties of mesenchymal type carbide. They are similar to electrical and thermal conductivity, high melting point, high hardness, brittleness and is also large.The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is bonded metalIs the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 degrees. In addition, nitrides, borides, silicides of transition metals have similar characteristics, can also act as a hardening in hard alloy the phase hardening phase due to the existence of alloy with high hardness and wear resistance.Bonding metals are generally iron based metals, and cobalt and nickel are commonly usedManufacture of hard alloy, the size of raw powder in 1 ~ 2 microns, and high purity. Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class then, after drying and sieving to prepare a mixture. Then, the mixture granulation, pressure type, heated to the melting point of the metal bond (1300 to 1500 DEG C) when hardening phase and bonding metal to form eutectic alloy. After cooling, the hardening phase distribution in grid bonded metal composition in each other closely together, form a firm whole. The hardness of the hard alloy depends on the hardening phase content and grain size, the hardening phase content is higher, more fine grain, hardness is greater. The toughness of cemented carbide by bonding metal bonded gold decision. The higher the content, the greater the flexural strength
- Q: What kind of carbide alloy is used in stainless steel processing?
- Such as: YA6; YH1; YW3. This kind of steel has high hardness, small amount of feed to lower cutting speed, cutting the depth is bigger, avoid hardening layer on the surface of the skin with the previous procedure (Note 2).
- Q: Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?
- This is the first use, each one has its own merits, hard alloy with high hardness, suitable for high speed drilling and high hardness materials, and high cobalt high speed steel has good toughness, suitable for low hardness material, suitable for drilling slower machine.
- Q: What is hard alloy grinding?
- Diamond grinding wheel in grinding hard alloy and non-metallic materials, has a unique effect, but in the grinding of steel material, especially grinding special steel, the effect is not significant. It is composed of cubic boron nitride (CBN) grinding cubic boron nitride particles sticking to the ordinary wheel surface only a very thin layer, the abrasive wear the hardness, toughness and durability of corundum wheel is 100 times, the most suitable for processing high hardness, high viscosity, high strength, low thermal conductivity of grinding hard steel and high or super high speed grinding.
- Q: the blade is hard alloy, the processing material is QT600, the plane lower tool margin is 4mm, the speed and the knife
- This belongs to the category of ductile iron, more difficult to process, because the material is hard particles, it is recommended around S=1200 F=400
- Q: What is the heat treatment process of cemented carbide?
- The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.
- Q: How are cemented carbides separated from the cutting tools?
- Tools are usually brazed by high-frequency induction:The blade part on the induction coil, through high frequency alternating current induction electromagnetic field, the induced electromotive force generated in the workpiece surface coupling, forming eddy current on the metal surface by eddy current heat generated in the metal surface, the welding parts usually coated with solder powder, welding can be reached until the melting temperature of workpiece. Take off the blade, too.
- Q: I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!
- Therefore, the processing of cemented carbide selection of the correct cutting fluid can produce good results, the general cutting fluid is not good, the quality of processing is very poor.
- Q: I've seen a lot of classification, what tools, hardware, machinery, machinery, metallurgy, minerals, etc.,But I always don't know what the hard alloy belongs to. What can I do for you?
- The original should belong to the tool industry, because the use of hard alloy cutting tools, cutting tools, do some, such as measuring. Now the application of cemented carbide is becoming more and more widespread, and it should be more machining.
