What is the difference between cemented carbide milling cutter and tungsten steel milling cutter
Carbide milling cutter is also called tungsten steel milling cutter. In the machinery industry, many products with the same time are called differently, which leads to unnecessary trouble, such as carbide milling cutter and tungsten steel milling cutter. Many people mistakenly use the milling cutter made of two kinds of raw materials. In fact, many people are brought into this misunderstanding because of the different names. In fact, tungsten steel milling cutter and carbide milling cutter are all milling cutters of the same raw material.
Use of carbide milling cutter: carbide milling cutter is generally used in CNC machining center and CNC engraving machine. It can also be installed on ordinary milling machine to process some hard and uncomplicated heat treatment materials.
1. Carbide cylindrical milling cutter: it is used for machining plane on horizontal milling machine. The cutter teeth are distributed on the circumference of the milling cutter and can be divided into straight teeth and spiral teeth according to the tooth shape. There are two kinds of teeth. Spiral tooth rough tooth milling cutter has less teeth, high tooth strength and large chip space, which is suitable for rough machining; fine tooth milling cutter is suitable for finishing.
2. Carbide face milling cutter: it is used for machining plane on vertical milling machine, end milling machine or gantry milling machine. There are cutter teeth on the end face and circumference, and there are also coarse teeth and fine teeth. There are three kinds of structures: integral, inlaid and indexable.

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
