Do you know what effect the simple improvement of milling cutter has?
The simple improvement of the milling cutter can improve the processing efficiency, extend the tool life, improve the processing accuracy, reduce the noise and vibration, broaden the application range, and bring more advantages to the processing process.

Master teaches you how to choose milling cutter
In short, when selecting a milling cutter, it is necessary to comprehensively consider the processing materials, cutting conditions, geometric features, processing methods and processing accuracy to ensure that the appropriate milling cutter is selected and the processing efficiency and quality are improved.
How much do you know about the basic knowledge of milling cutter? After watching the increase of knowledge!
White steel milling cutter Also known as high-speed steel, the hardness is relatively soft, the high-speed steel knife is cheap, and the toughness is good, but the strength is not high, it is easy to let the knife, and the wear resistance and thermal hardness are relatively poor. The thermal hardness of the high-speed steel milling cutter is about 600 degrees. When milling harder materials with white steel, it is easy to burn the knife if the coolant is not in place. This is one of the reasons why the low thermal hardness.
Why is the whole carbide milling cutter divided into 2 blades, 3 blades, 4 blades and 6 blades?
In theory, the more the number of cutting edges of the whole hard milling cutter, the higher its rigidity, the smaller the average cutting amount of the single edge, and the smaller the cutting resistance. The more the number of blades, the vibration and noise during cutting will be reduced, the accuracy of the product and the surface quality after processing will be better, and the life of the milling cutter will be extended accordingly with respect to the tool with less blades. Does that mean that we have to choose the milling cutter in the direction of the number of edges? The answer is no, we still have to choose according to the material and process.

Shanks of solid carbide milling cutters
The shank of the whole carbide milling cutter is mainly a straight shank of a complete cylinder and a cylindrical shank with a cutting plane (commonly known as "side-fixed" or "side-fixed shank").

Selection of Cemented Carbide Milling Cutter
Milling stainless steel in addition to end mills and some end mills and carbide for milling cutter materials, the rest of the various types of milling cutters are made of high-speed steel, especially tungsten-molybdenum and high vanadium high-speed steel has a good effect, the tool durability can be increased by 1-2 times than W18Cr4V. The carbide grades suitable for making stainless steel milling cutters are YG8, YW2, 813, 798, YS2T, YS30, YS25, etc.
