Requirements of Zhongshan tungsten steel milling cutter
Tungsten steel milling cutter is the common name of cemented carbide milling cutter. It is a universal tool made of cemented carbide data (tungsten titanium alloy). Generally used in CNC machining center, CNC engraving machine. It can also be installed on the general milling machine to process some relatively hard and not messy heat treatment data. Tungsten steel milling cutter is widely used and high-speed machining is used. The hardness of tungsten steel milling cutter is very high, usually in hra93-97 directly, second only to diamond. Because tungsten steel milling cutter is not easy to be worn, and its quality is brittle and firm, it is not afraid of annealing.
We all know that when users use tungsten steel milling cutter, the requirement is hardness. High hardness tungsten steel milling cutter can greatly improve the adaptability, operation speed, service life, etc., but how to improve the hardness of this kind of milling cutter is a problem, because not all milling cutters produced by all manufacturers have hardness advantage in the market. In order to improve the hardness of this kind of tungsten steel milling cutter, several conditions must be reached. One is to have good data. Tungsten steel milling cutter products are processed by data. Only good data can guarantee its hardness.
This is an important condition, but many manufacturers, either because their own production conditions have not reached, or to reduce production costs, use low-quality tungsten steel data, so it is difficult to have better hardness. Because the data do not have hardness, the milling cutter is difficult to show hardness. What kind of tungsten steel milling cutter data to choose depends on what it is Manufacturers, on the one hand, manufacturers should have the adaptability in production, but also have the corresponding reputation. Only when they reach these two points, can high-quality tungsten steel data be used to ensure the hardness of tungsten steel milling cutter.
High hardness tungsten steel milling cutter should not only improve the data, but also have better technology. As the best tungsten steel data, it is necessary to have better production requirements under the condition that the process is suitable. For example, in the production, the lack of manufacturability of the manufacturer will make the high-quality tungsten steel degenerate due to high temperature, and the transformed data will be difficult to have the original hardness 。 In the production of this kind of tungsten steel milling cutter, either in the molding time, or in the welding time, there are many will have high temperature environment, no high technology will make the tungsten steel raw materials degenerate due to high temperature.
Tungsten steel milling cutter has high requirements on the processing environment, and the quality of tungsten steel milling cutter will also affect the processing effect. Therefore, when you purchase, you can learn about the product information and select the appropriate tungsten steel milling cutter.

What are the causes of chip accretion on NC tools?
The reason is that the chip bottom metal is embedded in the micro uneven peak valley on the front cutter surface due to the large down pressure in the part close to the cutting edge, forming a gap free metal to metal touch, which is called the bonding area. In the bonding zone, there will be a thin layer of metal data accumulated on the rake face at the bottom of the chip. The metal data of this part of the chip is severely deformed and strengthened at the appropriate cutting temperature. With t

What are the wear types of tungsten steel milling cutters?
Abrasive wear machining materials often have some very hard particles, these particles will form grooves on the surface of the tool, which is the grinding loss. All surfaces are worn, especially the rake face. In addition, although the wear of hemp occurs at various cutting speeds, the wear caused by other reasons is not obvious due to the low cutting temperature at low cutting speed, so it is mainly the abrasion of abrasive materials. The lower the tool hardness is, the more serious the grindin
