Description

a mobile workbench

technical field

The utility model relates to the technical field of gantry milling equipment, in particular to a mobile workbench.

Background technique

Gantry milling machine, referred to as gantry milling machine, is a milling machine with a portal frame and a horizontal long bed. The gantry milling machine can use multiple milling cutters to process the surface at the same time, the machining accuracy and production efficiency are relatively high, and it is suitable for processing the plane and inclined plane of large workpieces in batch and mass production;

The traditional gantry milling is to process the surface by moving the milling cutter, so the processing accuracy sometimes cannot meet the processing requirements. At present, although the gantry milling on the market is designed with a worktable that can move laterally, it cannot be used for the work. It is necessary to adjust the inclination of the table. When processing the inclined surface of the workpiece, it is still necessary to move the milling cutter on the beam for processing. For this reason, we propose a mobile table.
