Description

Technical Field

[0001] The utility model mainly relates to the technical field of metal processing equipment, in particular to a milling machine for elevator processing. Background Art

[0002] The elevator guide rail is the safety rail for the elevator to travel up and down in the hoistway. It is installed on the hoistway wall and fixed to the hoistway wall by the guide rail frame and the guide rail bracket. The commonly used guide rail for elevators is the "T"-shaped guide rail. The processing of elevator guide rails is a complex and delicate process. It is usually processed by a milling machine. The plane depth that the milling machine can process will not exceed half of the tool diameter. This is because excessive depth will cause vibration and damage to the tool, affecting the processing effect and workpiece quality. However, the elevator guide rail needs to meet a certain depth. Therefore, when processing the elevator guide rail, it is necessary to first mill a certain depth, and then mill a certain depth again based on the first time. Usually two processes are required, and the overall processing efficiency is low. Utility Model Content
