Description

Technical Field

[0003] The invention belongs to the technical field of machinery, and particularly relates to an angle positioning device for a rotary cutting tool. Background Technique

[0004] A rotary cutting tool is a kind of tool in the processing industry. When manufacturing product parts, the material is fixed on a machine tool, and the machine tool drives the material to rotate at a high speed. The rotary cutting tool is used to cut the material rotating at a high speed, so that the material is processed into a finished product. In the prior art, when using a rotary cutting tool to process materials, most of the time, the worker holds the rotary cutting tool by hand and adjusts the feed angle and feed depth of the rotary cutting tool to cut the redundant material. However, when adjusting the feed angle and feed depth of the rotary cutting tool by holding it by hand, deviations often occur, reducing the quality of the product, and holding the rotary cutting tool by hand also increases the safety hazards in the processing process.
