FAQ

Carbide coated drill bit. Do you have one there?

5., the drill can be re coated after grinding, pre treatment should be done before coating. To increase the coating effect.

Is it hard to make carbide cutting tools for aluminum alloy?

High speed tool steel is essentially tool steel, but heat resistance is betterHard alloy is made of tungsten carbide, titanium carbide materials such as superhard materials. From the hardness and red hardness, high speed tool steel paima couldn't catch up. Although the name as "alloy" two words, it is actually a kind of metal ceramic.

What material is that ultrafine cemented carbide?

Comparison of high-end materials, suitable for high - quality products, are generally fine particles of products. Its hardness and strength are superior. So the price is relatively high

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.

Carbide coated drill bit will reduce the service life after grinding, how to avoid?

Hello, there is no way to avoid the problem of reducing the service life of the carbide coated drill bit after grinding;Cemented carbide bit, in its use, the surface coating, the blade has already been damaged, can not reach the integrity of the factory, so that it affects the service life of the drill bit,There is a need to be re grinding, coating, the coating has physical and chemical coating and coating, coating chemical now use more chemical coating basically is the tool coating at high temperature, so the temperature can cause 2 damage of cemented carbide substrate;So it also affects the service life;The effect of bit life, the most important is the geometric design of drill bit; before the design is not good, but when re grinding and grinding a good point, sometimes improve the service life, but the original drill must use will reduce the life of the;About those problems mentioned above, in fact, that is, some methods to improve the service life of the drill, upstairs can refer to

What is the difference between hard alloy and steel

Tungsten carbide hard alloy belongs to, but not necessarily tungsten steel, now Taiwan and Southeast Asian countries customers love to use the word if they talk with tungsten, carefully into the deep, we will find that most of us. Or to the hard alloy and tungsten steel the difference is: also called hard alloy tool steel or high speed steel, tungsten steel is the raw material for smelting molten steel in steelmaking process for adding tungsten as a, also called high speed steel or tool steel, the tungsten content in 15-25%, The hard alloy is used; powder metallurgy of tungsten carbide as subject and cobalt or other metal bonded together and sintered, the tungsten content of more than 80% in general. Simply put all the hardness more than HRC65 as long as things go can be called cemented carbide alloyIs a kind of tungsten carbide hardness between HRC85 and 92, is often used as a knife

What are the cemented carbides?

Tungsten cobalt carbideWC cutterThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.

What are the features of cemented carbide YG8 knives?

So professional, do not understand the normal, YG8 are used for processing pig iron and other artifacts
