The number of cutting edges is selected according to the cutting method of solid carbide milling cutter. For example, when cutting grooves with the same cutting width as the diameter of the tool, a larger chip holding slot is required, and a 2-flute end mill is generally selected. While in the cutting width of the smaller side cutting, should give priority to the rigidity of the tool, choose multi-flute solid carbide milling cutter.

The best solid carbide milling cutter edge length is selected according to the processing shape such as the depth of the groove shape. If you choose an end mill with too long cutting edge by focusing on the number of regrinds, chattering will occur and the characteristics of the end mill will not be fully utilized, making it difficult to achieve high precision finishing surfaces.

The number of cutting edges is selected by the cutting method of solid carbide milling cutter. For example, if the cutting width is the same as the cutting diameter of the groove cutting, a large chip slot is required, usually, the tool with 2 edges is used. While cutting a small width of the side cutting, the choice of tool rigidity priority multi-flute end mills.

By increasing the number of flutes, rigidity and machining efficiency (tool life) can be increased, but at the same time, chip evacuation will be weakened. However, the appropriate choice of cutting conditions can overcome the weakness of chip evacuation, and multi-flute is the direction of future development.

Cutting processing, the contact between the cutting edge and the workpiece is prone to high temperature of 800-1200 degrees, the cutting heat generated by the high temperature is transmitted to the cutting edge, the tool wear is transmitted to the workpiece, and the workpiece deformation chip takes away the cutting heat. What we expect. In the discharge of the chip at the same time, the chip and the front surface of the tool to produce friction and temperature rise, in the front surface of the tool to produce crescent wear (performance in depth), on the other hand, the rear surface of the tool and the workpiece friction heat rises sharply, resulting in the rear surface of the tool wear.

The coating maintains the strength and toughness of the tool body, while maintaining the high hardness and wear resistance of the surface, and at the same time, maintaining high red-hardness.

Solid carbide milling cutter processing characteristics.

According to the different organization of stainless steel at room temperature, stainless steel can be divided into ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, precipitation hardening stainless steel. Most factories process stainless steel, mainly 201 stainless steel, 304 stainless steel and 316 stainless steel. 201 and 304 materials, with ordinary carbide coated milling cutter, it is easy to process. And 316 material, or stainless steel contains more impurities and high hard, you need to choose stainless steel special tools.

1. Large cutting force

2. High cutting temperature

3. Easy to stick to the tool

4. Difficult to break the chip

5. Tool easy to wear

6. Large linear expansion coefficient
