Description

A milling cutter for side processing without burrs

technical field

The utility model relates to the technical field of milling cutters, in particular to a burr-free side-processing milling cutter.

Background technique

A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. The blades of existing milling cutters are set in one-way spiral, which will cause burrs on the workpiece when cutting the workpiece, that is, parts that do not meet the design requirements such as edges, flashes, and sharp corners. The dimensional accuracy, shape and position accuracy and surface roughness of the processed workpiece.

Utility model content

The purpose of this utility model is to solve the shortcomings and deficiencies in the above-mentioned prior art, and to provide a burr-free side milling cutter, the blade between the front edge and the rear edge of the milling cutter is in a reverse spiral dislocation Setting, when cutting, the front edge is upward for chip removal, and the rear edge is for downward chip removal. The cutting stability is good, which effectively solves the burr phenomenon of the workpiece during cutting, and improves the surface quality, dimensional accuracy and shape accuracy of the processed workpiece.

The technical solution adopted by the utility model to solve the technical problem is: a burr-free side milling cutter, including a milling cutter body, one end of the milling cutter body is provided with a front edge and a rear edge for cutting workpieces at the same time , the front edge is provided with 2 to 6 right-handed blades that spiral to the right and are equidistantly arranged, and the rear edge is provided with 2 to 6 left-handed blades that are counter-helical to the right-handed blades and are equidistantly arranged, so The right-handed blades and the left-handed blades are arranged in front and rear dislocation, the right-handed blades form right-handed sipe for upward chip discharge, and the left-handed blades form left-handed sipe for downward chip discharge.

Preferably, the edge surfaces of the right-handed blade and the left-handed blade are coated with a high-dura layer. In this way, the wear resistance of the cutting edge can be effectively improved, so that the service life of the milling cutter can be extended by 2 to 5 times on the original basis.

Preferably, there are four right-handed blades and four left-handed blades.

In summary, the blades between the front edge and the rear edge of the burr-free side machining milling cutter of the present utility model are arranged in a reverse spiral misalignment. When cutting, the front edge removes chips upward, and the rear edge Lower chip removal, good cutting stability, effectively solves the burr phenomenon when the workpiece is cut, and improves the surface quality, dimensional accuracy and shape accuracy of the processed workpiece.

Fig. 1 is a schematic structural view of a burr-free side machining milling cutter according to Embodiment 1 of the present utility model;

Fig. 2 is a partial cross-sectional structure diagram of a right-handed blade according to Embodiment 1 of the present invention.

In the figure, the milling cutter main body 1, the front edge portion 2, the rear edge portion 3, the right-handed blade 4, the left-handed blade 5, the right-handed sipe 6, the left-handed sipe 7, and the high dura layer 8.

detailed description

Example 1

The burr-free side milling cutter described in this embodiment 1, as shown in Fig. 1 and Fig. 2, includes a milling cutter body 1, and one end of the milling cutter body is provided with a front edge portion 2 and a The rear edge portion 3, the front edge portion is provided with 4 right-handed blades 4 that spiral to the right and are equidistantly arranged, and the rear edge portion is provided with 4 left-handed blades 5 that are reversely spiraled and equidistantly arranged with the right-handed blades. Wherein, the right-handed blades and the left-handed blades are arranged in front and rear misalignment, the right-handed blades form a right-handed sipe 6 for chip discharge upwards, and the left-handed blades form a left-handed sipe 7 for downward chip discharge between the left-handed blades.

In this embodiment, the blade surfaces of the right-handed blade and the left-handed blade are coated with a high-durability layer 8 . In this way, the wear resistance of the cutting edge can be effectively improved, so that the service life of the milling cutter can be extended by 2 to 5 times on the original basis.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the technical content of the present utility model in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model still belong to the scope of the technical solution of the utility model.
