Abstract

The invention provides a grooving knife, which belongs to the technical field of cutting tools. It solves the problem that the existing grooving knife is easy to shake after being used for a long time and the processing is not stable enough. The grooving knife comprises a triangular body, the middle part of the body is provided with mounting holes for screws to pass through, and cutting edges are provided at the three end corners of the body, and the cutting edges are all located on the side of the body. A chip breaker is provided on the rake face, a chip breaker is provided in the chip breaker, a limit groove is provided on the inner end of the body close to the chip breaker, and the sides of the limit groove are vertically arranged with the upper and lower end surfaces of the body. The grooving knife of the invention has the advantages of better positioning effect and higher processing precision.

Description

technical field [0001] The invention belongs to the technical field of cutting tools and relates to a grooving tool. Background technique [0002] At present, from a global perspective, cutting processing, as the main basic technology of manufacturing technology, is in a period of rapid development of manufacturing technology.
