Large CNC Gantry Milling

Large-scale CNC gantry milling is a machining equipment that should be widely used at present. Large-scale CNC gantry milling can process a wide range. It can process helical surfaces and various curved surfaces of flat groove and toothed parts. There are also many things worth learning and paying attention to in the machining process of CNC gantry milling. Below, Yuntuo large-scale machining factory will share with you some dry goods about large-scale CNC gantry milling. The protruding length of the workpiece to be processed is more than 4 times the diameter of the large CNC gantry milling machine, and it should be supported on the head of the milling machine by a top center frame or a follower rest according to the process regulations. When extending behind the milling machine, guards and warning signs should be added.

      Specific technical requirements require that the machined surface of the parts should not have surface defects such as scratches and wear. The dimensions of the parts should be removed, but the unmarked shape tolerance should meet the standard requirements, and the unmarked length dimension allowable deviation should be within a fixed range. When machining and assembling hydraulic systems, seal packings or sealants are permitted but should be prevented from entering the system. Before assembly, the machined parts should be cleaned and cleaned, free of burrs, flashes, oxide scale, colorants, dust, etc.

      For high-speed rotating parts and components should be dynamically balanced. Including static stiffness and dynamic stiffness, in addition to the stiffness of the components themselves, attention should also be paid to the contact stiffness, and the stiffness of the process system composed of the workpiece tool holder should be considered. Although the cutting force of precision machine tools and ultra-precision machine tools is not large, the deformation of the machine tools will have a great impact on the accuracy.

      Therefore, the workpiece can only be machined by rotating it by 1°. 255 has high productivity. The pitch accuracy of thread milling can reach grade 89, and the surface roughness is r50.63μM.
