What is the carbide end mill?
Carbide end mill is a type of industrial tool used for cutting and shaping metals and other solid materials. Although its appearance is similar to the appearance of a drilling bit, the end mill can cut in all lateral directions axially as a drill bit. End mills are often made of carbide, also called carbide tungsten. Carbide is a very hard and heavy material that can cut metal without breaking or scratching. End mills differ from other types because they have tooth cutting at one end and sides. End mills also have one or more "flutes", which means deep spiral grooves that run up and down the cutter.
The spiral shape of the flute gives two benefits. First, when the teeth cut the material, the chips are pulled from the cutting surface of the flute rotation. Second, the shape of the helix reduces vibration and gives a more polished surface than if the tooth has affected the material at the same time.
depending on the milling material and how the milling should be carried out, there are many types of carbide end mill, with different shapes and geometries. For example, if the material to be cut will be optimal. With a softer metal as aluminum, deeper flutes with sharp cutting edges will be more convenient.
high -speed steel was a traditional raw material for end mills, but most are now made of tungsten carbide. It is a highly rigid material that is extremely wear resistant, giving a carbide end mill longer than steel. Some of the more impressive properties of carbide include its high melting point, at 5,200 degrees of fahrenheite (2,870 degrees C). It also measures about 8.5 to 9.0 from 10 to Mohs Mineral harness. From Comparison, hardened steel measures only seven to eight.
Due to the accuracy of its production, the carbide end mill will usually be made by computer machines. Inside the machine, the mills are grounded with abrasive wheels mounted on V Vřetenech. The wheels are made of an industrial diamond, one of the few materials on the ground that is heavier than the tungsten carbide. Temperatures in these grinding machines are kept at bay with high -pressure lubricants, including oils, oil water emulsions and sometimes ordinary water.
