Vertical machining center, also known as CNC, is a highly automated multifunctional CNC machine equipped with a tool magazine and automatic tool changer. In Hong Kong, Taiwan, and Guangdong regions of China, there are also many people who use vertical machining centers, also known as computer gongs.
After the workpiece is machined once in the vertical machining center, the digital control system can control the machine tool to other processes, automatically select and replace tools, and automatically change the spindle speed, feed, tool to workpiece movement path, and other auxiliary systems of the machine tool. Complete multiple processes from different sides of the workpiece in sequence. In addition, there are multiple tool replacement or tool selection functions that can significantly improve productivity.
A vertical machining center is a CNC machine tool that integrates a spindle and a worktable, mainly suitable for processing composite parts of plates, disks, molds, and small shells. Vertical machining centers can complete processes such as milling, boring, drilling, tapping, and cutting threads. Vertical machining centers should have at least 3-axis 2-linkage, usually 3-axis 3-linkage. Some can have 5-axis and 6-axis control. The height of the column of a vertical machining center is limited, and there is a range limitation on machining box type workpieces, which is a disadvantage of vertical machining centers. But the workpiece clamping and positioning of vertical machining centers are relatively simple; The movement trajectory of cutting tools is easy to observe, and the debugger is convenient for inspection and measurement. If there are any problems during the machining process, they can be detected in a timely manner. Cooling conditions are easy to set, and cutting fluid can directly reach the tool and machining surface. The three coordinate axes are consistent with the Cartesian coordinate system, which is intuitive, visually consistent with the pattern, easy to remove debris, and avoids surface detachment and scratches.
What are the classifications of vertical machining centers?
1. According to the classification of monorails, vertical machining centers can be divided into hard rails and wire rails based on each axial guide rail. Hard rails are suitable for further cutting, while linear rails are more sensitive to movement.
2. According to the speed classification, the spindle motor speed of the vertical machining center is 6000-15000rpm for low-speed type, and 18000rpm or above for high-speed type.
3. According to structural classification, vertical machining centers can be divided into C-type and gantry type based on the bed structure.
