Description

Rough machining milling cutter for steel

Technical Field

The utility model relates to a milling cutter technical field specifically is a rough machining milling cutter is used to steel.

Background

A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. Milling cutters are mainly used for machining planes, steps, grooves, formed surfaces, cutting off workpieces and the like on milling machines, and in optimizing the milling effect, the blades of the milling cutter are another important factor, and it is an advantage if more than one blade participates in cutting at any one time, but it is a disadvantage that the number of blades participating in cutting at the same time is too large, and it is impossible to cut at each cutting edge at the same time, and the required power is related to how many cutting edges participate in cutting, and the position of the milling cutter relative to the workpiece plays an important role in terms of chip forming process, cutting edge load and machining result. In face milling, with a milling cutter that is about 30% larger than the cutting width and positioned close to the center of the workpiece, the chip thickness does not vary much. The thickness of the chip cut in and out is slightly thinner than the thickness of the chip cut in the center cut, and in order to ensure that a sufficiently high average chip thickness/feed per tooth is used, the number of cutter teeth suitable for the process must be correctly determined. The pitch of the milling cutter is the distance between the active cutting edges. The milling cutter can be divided into 3 types, namely a dense-tooth milling cutter, a sparse-tooth milling cutter and a super-dense-tooth milling cutter according to the value.

The existing milling cutter has the following defects: the length of the milling cutter is insufficient, so that some metal workpieces cannot be completely processed by the milling cutter, and the milling cutter is very inconvenient. We have therefore improved this and proposed a roughing milling cutter for steel.
