Description

Technical Field

[0001] The utility model relates to the technical field of drills, in particular to a drill bit for a numerical control lathe which is convenient for maintenance. Background Art

[0002] A numerical control machine tool, abbreviated as a CNC machine tool, is an automated machine tool equipped with a program control system. The control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device issues various control signals to control the actions of the machine tool, and automatically processes parts according to the shape and size required by the drawing.

[0003] However, in the prior art, during the normal operation of a numerical control machine tool, tools or drill bits are used to drill or grind the materials to be processed. During the use of the drill bit, the machine tool drives the drill bit to rotate at a high speed for processing. However, when the existing drill bit is installed on the machine tool, basically the bolt installation method is used, which is convenient for later replacement. But after installing the drill bit with bolts, when the machine tool drives the drill bit to rotate at a high speed, it may cause the drill bit at the bottom to vibrate, resulting in inaccurate drilling positions and wasting materials.
