Milling cutter
The types and uses of milling cutters are generally divided into:
1、Flat end milling cutter, rough milling, removing a large number of blanks, small area horizontal plane or contour finish milling.
2、Ball end milling cutter for semi finish milling and finish milling of curved surface. The knife can finely mill small chamfers on steep surfaces or straight walls.
3、The flat end milling cutter has chamfer, which can be used for rough milling to remove a large number of blanks, and can also be used for fine milling of small chamfer on the front face (relative to the steep surface).
4、Shape milling cutter, including chamfer cutter, T-shaped milling cutter or drum cutter, tooth cutter and internal R cutter.
5、Chamfer cutter, whose shape is the same as that of chamfer, is divided into milling cutters for circular chamfer and oblique chamfer.
6、T-knife, which can mill T-groove.
7、Tooth cutter, milling out various tooth shapes, such as gears.
8、Rough leather cutter is a rough milling cutter designed for cutting aluminum copper alloy, which can be processed quickly.
9、broach：Broach can be divided into integral broach and combined broach or assembled broach according to the mechanism. The internal broach of central specification is made into integral broach, while the internal broach of large specification and most external broach are made into combined broach.According to the broach tooth material, it is divided into high-speed steel broach and cemented carbide broach.
The internal broach is used to process the inner hole surface of various profiles, and its broach name is generally determined by the shape of the processed hole, such as round hole broach, square broach, hexagonal broach, keyway broach, spline broach, etc.
The internal broach can also process spiral internal splines and internal gears. The hole diameter that the internal broach can process is usually 10-120mm, which can be processed to 5-400mm in special cases. The broached groove width is generally 3-100mm, and the length of the hole is generally not more than 3 times the diameter, which can reach 2m in special cases.
The external broach is used to process the external surfaces of various ovens, such as planes, formed surfaces, grooves, complex mortises and tenons in steam turbines to replace the milling, planing, grinding and other processing of these parts. It is especially suitable for the surface of some parts in mass production such as automobiles, motorcycles, tractors and so on.
