Abstract

The utility model discloses a milling cutter for processing close angle work piece, including handle of a knife and tool bit, the handle of a knife is cylindric, the tool bit is fixed in handle of a knife one end, and evenly distributed has four spiral helicine sword teeth on the tool bit, the whole water droplet form that is of tool bit, the terminal size of tool bit is greater than the handle of a knife size. This milling cutter simple structure, mill convenient quick, can mill and to have the work piece that closes angle, angle of release and right angle structure.

Description

A kind of milling cutter closing angle workpiece for processing

Technical field

This utility model relates to process tool, is specifically related to a kind of milling cutter closing angle workpiece for processing.

Background technology

Milling cutter is cutter conventional in machine tooling, milling cutter is made up of handle of a knife and cutter head, the structures such as plane, step, groove can be milled out on workpiece, conventional milling cutter tip diameter is equal with handle of a knife or is less than handle of a knife, due to tip size and the restriction of shape, in the isostructural milling process of step or groove, milling cutter can only mill out the structure with right angle or angle of release, but for some has and closes the workpiece of corner structure, what current milling cutter was difficult to process workpiece closes corner structure.In order to solve the problems referred to above, this utility model provides a kind of and closes the milling cutter of angle workpiece for processing, and this milling cutter construction is simple, milling fast and easy, can mill out and have the workpiece closing angle, angle of release and right-angle structure.

Summary of the invention

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of milling cutter closing angle workpiece for processing, including handle of a knife and cutter head, described handle of a knife is cylindric, described cutter head is fixed on handle of a knife one end, being evenly distributed with four spiral helicine cutters tooth on cutter head, described cutter head is overall in drops, and cutter head tip dimensions is more than handle of a knife size.

This utility model has the advantages that owing to cutter head tip dimensions is more than handle of a knife, therefore during milling tool, both can mill out the groove that sidewall is right angle and angle of release, also can mill out sidewall is the groove closing angle, also can process other structures on the sidewall close corner structure simultaneously.

Labelling in figure: 1-handle of a knife, 2-cutter head, 3-cutter tooth.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, this utility model is expanded on further below in conjunction with the accompanying drawings.

As shown in Figure 1-2, a kind of milling cutter closing angle workpiece for processing, including handle of a knife 1 and cutter head 2, handle of a knife 1 is cylindric, and cutter head 2 is fixed on handle of a knife 1 one end, is evenly distributed with four spiral helicine cutters tooth 3 on cutter head 2, cutter head 2 entirety is drops, and cutter head 2 tip dimensions is more than handle of a knife 1 size.

Owing to cutter head 2 tip dimensions is more than handle of a knife 1, therefore during milling tool, both can mill out the groove that sidewall is right angle and angle of release, also can mill out sidewall is the groove closing angle, also can process other structures on the sidewall close corner structure simultaneously.

Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
