Q:Fuzhou where to buy steel tungsten carbide

How will you buy the blade right I can express to you

Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason

Hard to turn materials require different speeds and special turning tools. There is a reasonable amount of feed. Ordinary alloy knives are very easy to break

Q:We'll drill on the stainless steel column. Which bit is better?

High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.Serious work hardeningAustenitic stainless steel and some high alloy stainless steel is austenite, high work hardening tendency when cutting, usually plain carbon steel several times, the tool in hardening region cutting, shortening tool life.Easy to stick the knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts. ??Tool wear acceleratedThe materials generally contain high melting point elements, large plasticity, high cutting temperature, so that the tool wear faster, sharpening and changing knives frequently, thus affecting the production efficiency and improving the tool cost.Mainly to reduce the cutting line speed, feed. With special processing stainless steel or high temperature alloy cutting tools, drilling, tapping the best internal cooling

Q:What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?

YG8.YG6 series alloys belong to class YG alloys. YG8 is softer than YG6 alloy.

Q:Have seen many of the whole alloy cutting tool brand, I would like to ask, the global overall alloy cutting tool brand, which have quality and price advantage, I want to be a cheap brand regional agent!

The high-end products are M.A.FORD (Mei Fu) Sandvik, Kenna, guhring, Leitz, ISCA, WalterMost of the middle end is Korean and JapaneseLow-end is made in Taiwan

Q:Is Zhuzhou the largest cemented carbide producer in Asia?

Of course, yes, or how could the 601 factory be so famous? That's the old military enterprise. It's the hard tool factory now. I hope it can help you!

Q:What is the difference between them?From hardness, abrasion resistance analysis!

A total of 10 ~ 25%. Under the condition of heat generated in the high-speed cutting (about 500 C) can still maintain a high hardness of HRC can be more than 60. This is the main characteristic of high speed steel - red hardness. And carbon tool steel after quenching and low temperature tempering, at room temperature has very high hardness, But when the temperature is higher than 200 DEG C, the hardness decreased rapidly, at 500 DEG C hardness has been reduced to a similar degree with annealing state, completely lost the ability of metal cutting, which limits the production of carbon tool steel and high-speed steel cutting tools. The red hardness, make up for the fatal defect of steel with carbon. That can be used in the manufacture of cutting tools.

Q:YW1 what do you mean by "YW" in carbide cutter head?

Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy

Q:What is the hardness of YG8 cemented carbide?

The hardness of YG8 cemented carbide produced by Zhuzhou fine drill is 89.5, all of which are made of cemented carbide raw material

Q:Can ceramic tools process cemented carbides?

No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
