What is Zhongshan tungsten steel milling cutter? How to judge the quality of milling cutter?
Tungsten steel cutting tools have become an indispensable part of the machine tool professional use process, tungsten steel cutting tools related to the use of equipment quality, so that the smooth use of equipment. So what is tungsten steel tool?
Tungsten steel milling cutter is the common name of cemented carbide milling cutter, which is made of cemented carbide material (tungsten titanium alloy). Generally, it is mainly used for CNC machining and CNC engraving machine. It can also be installed on the ordinary milling machine to process some hard and uncomplicated heat treatment materials. Tungsten steel milling cutter is widely used and used in high-speed machining. The hardness of tungsten steel milling cutter is very high, generally in hra93-97 directly, second only to diamond. It is because tungsten steel milling cutter is not easy to be worn, and its quality is brittle and firm, and it is not afraid of annealing.
There are many kinds of tungsten steel milling cutters. The prices of the same shape milling cutters vary greatly. It is difficult for ordinary customers to judge whether they are good or bad. However, the following can easily determine whether they are good or bad
1. See the origin of cemented carbide for tungsten steel milling cutter. Trademarks. Generally, the price of imported cemented carbide materials is 2-3 times that of domestic materials. The prices of different brands also vary greatly.
2. By looking at the appearance, angle, appearance of the tungsten steel milling cutter, laser printing, the front end of the milling cutter, the flat cutter teeth, the uniform cutting edge of the rear corner, any chipping edge, burr, crack, etc. of tungsten steel milling cutter, it can be concluded that the manufacturing process of tungsten steel milling cutter is the processing production or the ordinary machine production. The accuracy of cutting tools is several times of that of ordinary machines.
3. The tail handle of drill bit is flat and chamfered in the same way, the inner and outer packing, the label is reported, and the name of the manufacturer is complete.
With the above points, we can determine whether the milling cutter is the original factory. Make clear of the above points, you can choose to buy according to the requirements of the workpiece for the tool.

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
