Working Principle Of CNC Gantry Milling Machine

Gantry milling machine is composed of portal frame, bed workbench and electrical control system. The portal frame is composed of columns and top beams, with beams in the middle. The beam can move up and down along the two column guide rails. There are 1 ~ 2 milling heads with vertical spindle on the beam, which can move laterally along the beam guide rail. 

A milling head with a horizontal spindle can also be installed on the two vertical columns, which can move up and down along the column guide rail. These milling heads can process several surfaces at the same time. Each milling head has a single motor (power up to 150 kW), speed change mechanism, control mechanism and spindle components.
