The types of milling cutters can be divided into sharp-toothed milling cutters and shovel-tooth milling cutters according to the cutter tooth structure. According to the relative position of the axis of the cutter teeth and the milling cutter, it can be divided into cylindrical milling cutter, angle milling cutter, face milling cutter, forming milling cutter, etc. According to the shape of the cutter teeth, it can be divided into straight tooth milling cutter, helical tooth milling cutter, angular tooth milling cutter, and curve tooth milling cutter. According to the tool structure, it can be divided into integral milling cutter, combined milling cutter, group or complete set of milling cutter, toothed milling cutter, clamp welding milling cutter, indexable milling cutter, etc. However, it is usually divided into the form in which the cutting teeth are machined.
1. Sharp-tooth milling cutter
Sharp-tooth cutters can be divided into the following types:
(1) Face milling cutter There are integral face milling cutters, toothed face milling cutters, machine clamp indexable face milling cutters, etc., which are used for rough semi-finishing and finishing of various planes and step surfaces.
(2) End mill is used for milling step faces, sides, grooves, grooves, holes of various shapes on the workpiece, and inner and outer curve surfaces.
(3) Keyway cutter is used for milling keyway, etc. (4) Slot milling cutter and saw blade milling cutter are used for milling various grooves, sides, step surfaces and sawing, etc. (5) Special slot milling cutter is used for milling various special grooves, including T-slot milling cutter, half-moon keyway milling cutter, dovetail groove milling cutter, etc.
(6) Angle milling cutter is used for straight grooves, spiral grooves, etc. of milling tools.
(7) Mold milling cutter is used for milling the convex and concave forming surfaces of various molds.
(8) Group of milling cutters Combine several milling cutters into a group of milling cutters, which are used for milling complex forming surfaces, surfaces and wide planes of different parts of large parts.
2. Shovel tooth milling cutter
The shovel tooth milling cutter is characterized by the back of the tooth being shoveled, and the milling cutter is only sharpened in front with a blunt back, which is easy to maintain the original shape of the cutting edge, so it is suitable for cutting workpieces with complex profiles, such as profile milling cutters.
