Light portal type engraving and milling machining center

The invention discloses a light portal type engraving and milling machining center, and belongs to the technical field of machining equipment. The light portal type engraving and milling machining center solves the problems that an existing numerical control engraving machine cannot achieve concentrated machining of various working procedures and is low in engraving and milling efficiency. The light portal type engraving and milling machining center is composed of a PC, a control system and a machine tool body. The machine tool body comprises a lathe bed, a stand column, an X-axis lead screw, an X-axis dragging plate, a Z-axis sliding plate, a Z-axis servo motor, a workbench, a Y-axis lead screw, a tool magazine, a tool changer and tools. By the adoption of a numerical control system, the tool magazine and the automatic tool changer are arranged, highly automatic workpiece machining can be achieved; concentrated machining of the various working procedures such as milling, drilling, boring, reaming and tapping can be performed after a workpiece is clamped at a time; and the cost of the machining center is greatly lowered. Machining is controlled intelligently through the diversification control system, labor force is saved, the cost is saved, and the production efficiency is improved.
