Novel milling cutter

Abstract

The invention aims to overcome the defects in the prior art, and provides a novel milling cutter having the advantages of reasonable structure, convenience for chip removal, quick processing speed, low production cost and long service life. Compared with the prior art, the novel milling cutter has the prominent advantages of reasonable structure, convenience for processing and lower production cost; a groove is formed in an end edge, so that iron chips can be fed in a chip removing groove through the groove, the chip removal is convenient and reliable, and the chip bonding phenomenon is not occurred; as chamfered teeth consisting of a first angle, a second angle and a third angle are adopted, the structure of a chamfered milling cutter is simplified, and the processing speed is increased; and the novel milling cutter has a long service life, and can satisfy the actual use requirements.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a milling cutter. [0002] Background technique [0003] At present, most milling cutters have a single function. During the machining process, the chip removal of the blade is not smooth, and the end edge of the cutter tooth is easy to stick chips, which leads to increased tool wear, reduced cutting ability, and shortened service life. In addition, due to the use of bolts, it is necessary to counterbore the base. The processing speed of existing tools for counterbore is often slow, the efficiency is not high, and the left and right torques are large, resulting in shortened service life of the tool. Chamfer milling cutters are used to mill out chamfers. For the processing of ordinary aluminum alloy materials, the commonly used high-precision, high-speed chamfer milling cutters have complex structures, high manufacturing costs, and do not meet the actual use requirements.

Problems solved by technology

[0003] At present, most of the milling cutters have a single function. During the machining process, the chip removal of the blade is not smooth, and the end edge of the cutter tooth is easy to stick chips, which leads to increased tool wear, reduced cutting ability, and shortened service life.

In addition, because of the use of bolts, it is necessary to sink holes in the base. The processing speed of existing tools for counterbore holes is often slow, the efficiency is not high, and the left and right torques are large, resulting in shortened tool life.

Chamfer milling cutters are used to mill chamfers. For the processing of ordinary aluminum alloy materials, the commonly used high-precision, high-speed chamfering milling cutters have complex structures and high manufacturing costs, which do not meet the actual use requirements.
