The vertical machining center is a highly automated multi-functional CNC machine tool equipped with a tool magazine and an automatic tool changer.
After the workpiece is processed once in the China CNC vertical machining center, the digital control system can control the machine tool to other processes, automatically select and replace the tool, and automatically change the spindle speed of the machine tool, feed and the moving path of the tool to the workpiece and other auxiliary systems. The processing of multiple processes is completed in sequence from different sides of the workpiece. In addition, there are a variety of tool change or tool selection functions that can greatly increase productivity.
The vertical machining center is a CNC machine tool that integrates the spindle and the worktable. It is mainly suitable for processing plates, discs, molds, and small shell composite parts. Vertical machining centers can perform operations such as milling, boring, drilling, tapping by cnc tapping machine, and thread cutting. The vertical machining center has at least 3 axes and 2 linkages, generally 3 axes and 3 linkages. Some are capable of 5-axis (5 axis cnc machining center and 5 axis vmc machine)and 6-axis control. The height of the column of the vertical machining center is limited, and the range is limited in the processing of box-type workpieces, which is the disadvantage of the vertical machining center. However, the workpiece clamping and positioning of the vertical machining center are relatively simple; the movement trajectory of the cutting tool is easy to observe, the debugger is convenient for inspection and measurement, and if there is any problem during the processing process, it can be found in time. The cooling conditions are easy to set, and the cutting fluid can directly reach the tool and the machined surface. The three coordinate axes are consistent with the Cartesian coordinate system, which is intuitive, the pattern is visually consistent, the debris is easy to remove, and the surface that is peeled off and scratched is avoided.
1. According to the classification of a single rail, it can be divided into the hard rail and linear rail according to each axial guide rail of the vertical machining center. Hard rail is suitable for re-cutting, and linear rail movement is more sensitive.
2. According to the speed classification, the spindle motor speed of the vertical machining center is 6000-15000rpm for low-speed type, and above 18000rpm is for high-speed type.
3. According to the structure classification, the vertical machining center can be divided into C type and 5 axis gantry machining center according to the structure of the bed.
