Description

A compound chip breaking milling cutter

technical field

The utility model relates to the technical field of milling cutters, in particular to a compound chip breaking milling cutter.

Background technique

A milling cutter is a rotary tool with one or more teeth for milling. Each tooth cuts off the allowance of the workpiece intermittently during operation. The milling cutter is mainly used for machining planes, steps and grooves on a milling machine. Slots, forming surfaces and cutting workpieces, etc., when optimizing the milling effect, the insert of the milling cutter is another important factor. In any milling, it is an advantage if the number of inserts participating in cutting is more than one at the same time, but the number of inserts participating in cutting at the same time is an advantage. Too much is a disadvantage. It is impossible for each cutting edge to cut at the same time during cutting. The required power is related to the number of cutting edges participating in the cutting. In terms of the chip formation process, cutting edge load and processing results, the milling cutter is relative to the workpiece. The position plays an important role. When face milling, use a milling cutter that is about 30% larger than the cutting width and position the milling cutter close to the center of the workpiece, so the chip thickness does not change much, and the chip thickness in the cut-in and cut-out It is slightly thinner than the cutting thickness when cutting at the center, but the existing milling cutter has long chips and no chips, which has a bad influence on the automatic wire processing line and has low efficiency.

Utility model content

The purpose of the present utility model is to provide a composite chip-breaking milling cutter to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a composite chip-breaking milling cutter, comprising a tool handle, one side of the tool handle is provided with a cutter body, and one side of the cutter body is fixedly connected with a blade, The outer side of the cutter body is provided with a profile groove.

As a preferred solution of the present invention, the outer side of the cutter body is provided with a chip removal groove.

As a preferred solution of the present invention, a cutting fluid spray hole is arranged inside the cutter body.

As a preferred solution of the present invention, the inside of the cutter body is provided with a thimble process hole.

As a preferred solution of the present invention, the outer side of the tool handle is fixedly connected with a tool change handle grab handle, and the inside of the tool change handle grab handle is provided with a fixing groove.

As a preferred solution of the present invention, the material of the blade is PCD.

Compared with the prior art, the beneficial effects of the present utility model are: the utility model can realize one-time milling chip processing to complete the processing content, and the effect is good, the chips are cut off by the milling chip method, and the chips are prevented from being rolled up and entangled, thereby avoiding aluminum chips. If it is stuck on the tool or fixture, the cooling efficiency of the milling cutter can be improved through the setting of the cutting fluid spray holes, and the high temperature of the milling cutter can be avoided, which will reduce the service life of the milling cutter.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 , the present utility model provides a technical solution: a composite chip-breaking milling cutter, comprising a shank 1, one side of the shank 1 is provided with a cutter body 4, and one side of the cutter body 4 is fixedly connected with a blade 8. A profile groove 7 is provided on the outer side of the cutter body 4 .

The outside of the cutter body 4 is provided with a chip removal groove 2, which can be used to quickly discharge chips to avoid chip accumulation and affect the work of the milling cutter; the interior of the cutter body 4 is provided with a cutting fluid spray hole 3, which sprays the cutting fluid Hole 3 can improve the heat dissipation efficiency of the milling cutter, avoid the high temperature of the milling cutter, which will reduce the service life of the milling cutter; the inside of the cutter body 4 is provided with a thimble process hole 5; 9. The inside of the handle 9 is provided with a fixing groove 6, which can facilitate people to fix the handle 1; the material of the blade 8 is PCD, which has high hardness, good wear resistance, and good strength and toughness. , heat and corrosion resistance, so that the service life of the blade 8 is longer.

Specifically, during use, the milling cutter is installed on the CNC machine tool, the CNC machine tool drives the milling cutter to rotate, the blade 8 processes the workpiece, and the chips are cut off by milling chips during processing, so as to avoid aluminum chips from being stuck on the tool or fixture.
