The Longmen milling machine is primarily a machine tool that uses a boring tool to bore holes on the workpiece. Generally, the boring tool rotates as the main motion, and the movement of the boring tool or workpiece is the feed motion. Its processing accuracy and surface quality are higher than those of drilling machines. Longmen milling is the primary equipment for processing large box parts. Longmen planer and milling machine is an electromechanical integrated product that combines functions of planing, milling, and grinding. Suitable for processing various black metal, non-ferrous metal, and some non-metallic materials with high-speed steel and hard alloy cutting tools. It can complete the process of planing, milling, and grinding for flat surfaces, inclined surfaces, side surfaces, grooves, racks, and other processes.

Longmen planer and milling machine is a new type of machine tool developed by many senior experts who have been engaged in the planning and production of Longmen planer machine tools for many years based on the traditional Longmen planer. Its functions converge the advantages of advanced machine tools and are equipped with advanced electrical appliances to upgrade the electromechanical control technology. Equipped with milling heads and grinding heads, it can complete functions such as planing, milling, grinding, drilling, and countersunking. Equipped with right angle accessory milling heads, it can clamp workpieces in one go, complete five sided machining, and have multiple uses, improving the machining quality and production power of workpieces.
