Which grade of carbide milled copper plate is better 5

Generally speaking, the grade is YT15, YG9, the larger the number after that, it means that the cemented carbide contains more bonding, high toughness, low hardness, and poor wear resistance, so you can choose according to the performance of the cemented carbide required by the milled copper plate.

The hardness of copper is not large, so the cemented carbide should choose high wear-resistant and micro-grained ones, which can reflect the best performance of cemented carbide. In terms of grades, Sumitomo is H1 and EH10, and the domestic ones are not very well understood. But it must also be highly wear-resistant and microcrystalline.

If it is a finished knife, then some brands will develop separate model specifications specifically for aluminum and copper.

For example, I have a special milling cutter for aluminum and copper here.

yt14。Because the copper material is soft, the surface gloss is good after processing with this knife.

Please refer to it!

I agree with the statement of the third floor.,But I'm disgusted to write it as x dared! Hehe! In fact, most of the matrix materials before coating are made of general YG cemented carbide, and in fact, some foreign matrix materials are not as good as ours!

But the coating technology is good! In the end, the blade is better than our domestic one! Whether you admit it or not, accept it!

It's a fact!

The general steel parts are used Toshiba's model T9015.

The machining of quenched steel can have ceramic inserts, diamond, cubic boron nitride inserts are optimal. (The blade of cubic boron nitride depends on whether you can use it, which is quite expensive.) ）

All use Israel IC907, you go to buy it to know, the blade is very easy to use, our factory uses this...

I recommend you to use PCD tools for machining magnesium alloy, regardless of the finish and life are cemented carbide is not better, this is also according to the situation in your factory, with cemented carbide you can choose YG3 grade to try.

k10.The tool parameters are important, and the tool finish should be good. It is recommended to use a custom-made milling cutter on a machining center.

Magnesium alloy is relatively soft, and the sticky knife is more powerful during processing.

The main basis for the reasonable selection of insert carbide grades is the properties of the material to be processed and the properties of the cemented carbide. Generally, when the milling cutter is selected, the corresponding grade of cemented carbide insert can be equipped according to the processing materials and processing conditions provided by the tool manufacturer.

Due to the different composition and performance of the same kind of cemented carbide produced by each factory, and the expression method of cemented carbide grade is also different, for the convenience of users, the International Organization for Standardization stipulates that cemented carbide for cutting is divided into three categories according to its chip removal type and processed material: P class, M class and K class. According to the material to be processed and the applicable processing conditions, each category is divided into several groups, expressed by two Arabic numerals, the larger the number in each category, the lower the wear resistance and the higher the toughness.

Class P alloys (including cermets) are used to process metal materials that produce long chips, such as steel, cast steel, malleable cast iron, stainless steel, heat-resistant steel, etc.

Class M alloys are used to process ferrous or non-ferrous metals that produce long and short chips, such as steel, cast steel, austenitic stainless steel, heat-resistant steel, malleable cast iron, alloy cast iron, etc.

Class K alloys are used to process ferrous metals, non-ferrous metals and non-metallic materials that produce short chips, such as cast iron, aluminum alloys, copper alloys, plastics, hard bakelites, etc.

Maximum depth of cut:

Different series of indexable surface milling cutters have different maximum cutting depths. The larger the maximum depth of cut, the larger the size of the insert used in the tool, the higher the **, so from the perspective of saving costs and reducing costs, the selection of tools should generally be based on the maximum margin of machining and the maximum depth of cutting of the tool to select the appropriate specifications. Of course, it is also necessary to consider that the power rating and rigidity of the machine should be sufficient for the maximum depth of cut of the tool.

YG and YT classes are better.

Tungsten carbide grades can usually be divided into three categories: YG class (WC-CO class): This type of cemented carbide made of tools has good toughness, wear resistance, thermal conductivity, etc., mainly used for processing cast iron, non-ferrous metals and non-metals.

YT class (WC-TIC-CO): due to the addition of TIC to the material, the hardness and wear resistance of the material are improved, but the flexural stiffness is reduced. This kind of cemented carbide has high hardness and high heat resistance, good anti-bonding and oxidation resistance, and is suitable for processing steel, with low tool wear and high durability during cutting.

YW (WC-TIC-TAC-CO): TAC is added to YT material to improve the strength, toughness and red hardness of the tool. This kind of cemented carbide material has high high-temperature hardness, high-temperature strength and strong oxidation resistance, especially suitable for processing various high-alloy steels, heat-resistant alloys and various alloy cast iron.
