Description

Fast-forward milling cutter for aluminum

Technical Field

The utility model relates to a milling cutter technical field specifically is a give aluminium fast forward and use milling cutter.

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. Milling cutters can be divided into 3 types according to the value, namely a dense-teeth milling cutter, a sparse-teeth milling cutter, a super-dense-teeth milling cutter, and a main deflection angle of a face milling cutter related to the thickness of milled chips, wherein the main deflection angle is an included angle between a main cutting edge of an insert and the surface of a workpiece, mainly comprises angles of 45 degrees and 90 degrees and a circular insert, and the direction change of cutting force is greatly changed along with the difference of the main deflection angle: the milling cutter with the main deflection angle of 90 degrees mainly generates radial force to act in the feeding direction, which means that the processed surface is not subjected to excessive pressure, the milling cutter is relatively reliable for milling workpieces with weak structures, the radial cutting force and the axial direction of the milling cutter with the main deflection angle of 45 degrees are approximately equal, so the generated pressure is relatively balanced, the requirement on the power of a machine tool is relatively low, the milling cutter is particularly suitable for milling short-chip material workpieces generating broken chips, and the milling cutter with a circular blade means that the main deflection angle is continuously changed from 0 degree to 90 degrees, which mainly depends on the cutting depth. The cutting edge strength of the insert is very high, a large feed is suitable because the chips generated in the direction of the long cutting edge are thin, the direction of the cutting force in the radial direction of the insert is constantly changing, and the pressure generated during machining will depend on the cutting depth. The development of the geometric groove shape of the modern blade ensures that the circular blade has the advantages of stable cutting effect, lower requirement on the power of a machine tool, good stability and the like. It is no longer an effective roughing mill and has found widespread use in face milling and end milling.

At present, when a part is machined and rotated by the fast-forward aluminum milling cutter, the part is easy to wear for a period of time, the part is difficult to drill, and the cutter head is easy to damage, so that the machining and drilling efficiency is reduced. We have therefore improved this and have proposed a milling cutter for fast forward feeding of aluminium.
