technical field

The utility model relates to the field of machine tools, in particular to a fully automatic gantry milling machine.

Background technique

Milling machine (milling machine) mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece (and) the milling cutter is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

A milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves (key slots, T-shaped slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotating body and perform cutting work. When the milling machine is working, the workpiece is installed on the worktable or the accessories such as the indexing head. The main movement of the milling cutter is the rotation, supplemented by the feed movement of the worktable or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-blade intermittent cutting, the productivity of the milling machine is high. Simply put, a milling machine is a machine tool that can mill, drill and bore a workpiece.
