Diamond large hole saw

Abstract

The present invention discloses a diamond large hole saw which comprises a cylindrical cavity made of diamond. A through hole is formed in the position, in the central line, of the rear side of the cylindrical cavity. A threaded pipe is arranged in the through hole. Two bypass holes are formed in the two sides of the through hole, and the bypass holes are mounted in cooperation with a power shaft. A plurality of cutting liquid adding holes are formed in the side wall of the cylindrical cavity. The bottom of the cylindrical cavity is hollow. A plurality of grinding grooves are formed in the front edge of the cylindrical cavity. According to the diamond large hole saw, the grinding grooves are made of diamond, structural rigidity is high, and cutting precision and cutting strength are guaranteed. The power shaft and the threaded pipe are cooperatively mounted, and are reinforced through the two bypass holes, and hole drilling precision is guaranteed. The cutting liquid adding holes are formed below the cylindrical cavity, cutting liquid is firstly injected into the cylindrical cavity, then outer cutting liquid passes through the cylindrical cavity, the cutting process is guaranteed to be even, and a hole clamping object cannot be damaged.

Description

technical field [0001] The invention relates to a diamond large hole opener, which belongs to the technical field of diamond drilling tools. Background technique [0002] Diamond is a mineral composed of carbon. It is the hardest substance in nature. It has many important industrial uses, such as fine abrasive materials, high-hard cutting tools, various drill bits, wire drawing dies, and is also used as a tool for many precision instruments. The component is a material with excellent properties such as superhardness, wear resistance, heat sensitivity, heat conduction, semiconductor and penetration. Diamond has high hardness. In industry, diamond is mainly used to manufacture probes and grinding tools for drilling. The diamond hole saw is one of the diamond tools. It is installed on an ordinary electric drill and can easily make round holes, square holes, triangular holes, etc. Arbitrary cutting of holes, straight lines and curves. The existing diamond hole saws have diffe...

AI Technical Summary

Problems solved by technology

The existing diamond hole saws have different sizes and models according to different applications. For some plates that need to be processed with larger apertures, diamond hole saws will be used. Although this design of hole saws can complete drilling The operation of the hole, but due to the long-time punching operation, it will cause the wear of the puncher and reduce the quality and efficiency of the punching
