Introduction
CNC gantry milling machine is a high-precision metal cutting machine tool, which is widely used in the aerospace, automotive, medical, electronics, military and other industries. It is a common equipment for the machining of complex large metal parts in the industrial field. It has the advantages of high machining accuracy, large cutting force, high machining efficiency and high product quality.
Gantry milling machine is characterized by a gantry frame structure and a numerical control system. The frame is consist of two columns that are parallel to each other and are connected by a beam. The beam can move along the two columns and can move in the Y-axis direction. The table is located on the frame and the spindle is mounted on the beam. The spindle can move along the X-axis. The table can move along the Y-axis. The workpiece can move along the Z-axis according to the machining requirements, and is fixedly clamped on the table through the special clamping device. The coordinate system of the numerical control system of the CNC gantry milling machine is set according to the position of the tool, and the movement track of the tool and the workpiece is controlled by the computer.
Gantry milling machine uses a NC system to store machining programs and transfer machining instructions, so it can realize automated machining. TheNC program records the cutting feedrate, cutting depth, cutting direction, coordinate origin, control code and so on. Through the program, parts can be machined from different directions and various geometric shapes can be obtained, which greatly improves the machining accuracy and processing efficiency. Gantry milling machine can process complex curved surfaces, and the machining accuracy can reach ±0.02mm.
Gantry milling machine has a wide range of applications. It can process various complex parts and special-shaped parts with curved surface, plane or arc. It can process parts such as large template, disc, cabinet shell, flange, hole and curved surface. It is usually used for the machining of large and medium-sized molds and complicated parts.
Conclusion
CNC gantry milling machine is a key equipment in industrial machining, which plays an important role in the development of modern industry. It is widely used in the processing of molds, parts and complex parts and has the advantages of high production efficiency and high precision. With the development of computer control technology and the continuous improvement of control stability and control accuracy, the application of CNC gantry milling machine in industrial production is becoming more and more extensive.
