Numerically-controlled machine tool stable in use and high in precision

Abstract

The invention discloses a numerically-controlled machine tool stable in use and high in precision, and belongs to the field of high-precision numerically-controlled machine tools. The numerically-controlled machine tool stable in use and high in precision can achieve the effects that after a drill bit is used for a period of time, certain use fatigue may be accumulated in a drill bit body, when the drill bit is about to be abraded, the fatigue accumulation limit of the drill bit causes breaking of the drill bit, through reasonable structural design, a breaking point of the drill bit is designed on the inner side of a tool apron, chippings flying at a high speed are not prone to being generated due to breaking of the high-precision drill bit, workers are not prone to being hurt, meanwhile,the breaking point of the high-precision drill bit is reasonably designed, so that the breaking chippings are not prone to being left in the tool apron, subsequent replacement of the high-precision drill bit is not prone to being affected, a cleaning strength of the chippings inside the tool apron is reduced, the effect of warning technicians to replace the drill bit in time can be achieved, and the situation that due to abrasion of the drill bit, batches of defective products with precision not reaching the standard are generated is not prone to occur.

Description

technical field [0001] The invention relates to the field of high-precision numerical control machine tools, and more specifically relates to a stable and high-precision numerical control machine tool. Background technique [0002] CNC machine tool is the abbreviation of Computer numerical control machine tools, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. The processing problem is a flexible and high-efficiency automatic machine tool, which represents the development direction of mo...

Problems solved by technology

[0004] No matter how high-precision CNC machine tool it is, when the drill bit it uses wears, it will have an undue influence on the machining accuracy of the CNC machine tool. However, if the drill bit has a small amount of wear, it is still in the working process and the parts cannot be inspected by the naked eye. For inspection, usually a batch of products is produced and then batch inspection is carried out, so for high-precision production, there will be a large number of defective products, which will affect normal production
