Abstract

The utility model relates to the technical field of cutters, in particular to a micro-texture hard alloy end mill, wherein a circular pit micro-texture array unit is arranged on the front surface of the cutter and consists of circular pits which are sequentially arranged, the depth of the pits is kept unchanged, and the circular pit micro-texture array unit forms a micro-texture structure on the surface of the cutter. The circular pit micro-texture can reduce the stress of the hard alloy milling cutter when cutting high manganese steel and improve the service life of the cutter.

Description

Micro-texture hard alloy end mill

Technical Field

The utility model relates to a micro-texture hard alloy end mill, which is applied to the field of high manganese steel processing.

Background

The hard alloy end mill plays an important role in the high manganese steel processing industry, is mainly used for processing step surfaces and forming surfaces, has excellent wear resistance of high manganese steel, and is widely applied to wear-resistant parts such as tanks and tractor tracks, railway rails, trolley wire turnouts, and tracks of urban internal track traffic. However, the work hardening phenomenon is serious due to the high manganese content in the high manganese steel. Under the normal processing condition, the milled high manganese steel is easy to break, the service life of the cutter is greatly shortened, and the micro-texture is processed on the cutter. The micro-texture can reduce stress concentration during milling and improve the service life of the cutter.

Disclosure of Invention

The utility model aims to provide a micro-texture hard alloy end mill which is used for improving the service life of a cutter.

In order to solve the technical problems, the technical scheme provided by the utility model is that the micro-texture hard alloy end mill has a basic structure comprising a handle, a neck, a cutting edge and a circular micro-texture array unit. The end mill cutting edge is provided with a circular micro-texture array unit, the circular micro-texture array unit consists of circular pits with the same side length, and the circular micro-texture array unit forms a micro-texture structure on the surface of the cutter.

In one embodiment, all circular pits are 30um deep.

In one embodiment, the circular inter-pit spacing is 30um.

Compared with the prior art, the circular micro-texture array unit has the characteristics that the stress of the cutter can be reduced, so that the service life of the cutter is prolonged.
