Description

Alarm bores equipment of milling Technical Field The application relates to the field of drilling and milling equipment, in particular to an alarm drilling and milling equipment. Background The outer shell of the explosion-proof audible and visual alarm is an important structural member and a protective member, is usually made of a metal material, and needs to be subjected to multiple precise machining such as milling, drilling, tapping and the like to form multiple high-precision characteristics such as a mounting plane, a cable leading-in hole, a threaded hole, a sealing groove and the like, so that the overall structural strength, the explosion-proof level and the sealing performance of a product are ensured. In the related art, the alarm shell has processing characteristics on multiple surfaces, and a common processing mode is to form a production line by adopting a plurality of single-function machine tools such as a vertical milling machine, a drilling machine, a tapping machine and the like, so that operators circulate workpieces among various working procedures, and the processing of different surfaces is finished sequentially.
