The structure of the vertical machining center refers to the machining center with the spindle and the worktable set in a vertical state. The vertical machining center integrates the characteristics and functions of a variety of CNC machine tools.
The vertical machining center is developed from the basic CNC milling machine, and it also integrates the characteristics and functions of the CNC milling machine. Its structure is basically the same, and the processing technology is somewhat similar.
The difference between the vertical machining center and the CNC milling machine is that the machining center has an automatic Tool changer and tool magazine, but CNC milling machine does not have this function. The vertical machining center can complete multi-process machining such as milling, boring, drilling, tapping, and threading by clamping the workpiece at one time, and the vertical machining center can achieve at least three axes and two linkages, and the general vertical machining center can achieve three axes and three Linkage, and some can carry out five-axis and six-axis control, the more the number of control axes, the wider the processing range.
The advantages of vertical machining centers mainly include the following three points:
- 1. Since the structure of the vertical machining center is simple and easy to understand, it is very easy to clamp the workpiece. The same fixtures can be used, such as flat-nose pliers, pressure plates, indexing heads, rotary table and other fixtures to clamp the workpiece. The clamping positioning and repeated positioning of the workpiece are very convenient.
- 2. The structure of the vertical machining center is conducive to cooling. Because the coolant sprays the coolant from top to bottom, it can be sprayed directly onto the high-temperature workpieces and tools during processing.
- 3. The structure of the vertical machining center is relatively simple, so its field of view is very wide. It can observe the running track of the tool, and it is also convenient to debug, observe and modify the parameters. It is also convenient to measure the workpiece. When a problem is found, it will be stopped immediately for processing and modification.
- 4. The vertical machining center is easy to remove chips when machining flat workpieces, and the generated chips are washed away by the sprayed coolant, avoiding the debris from scratching the surface of the workpiece during cutting.
- 5. Compared with the horizontal machining center, the structure of the vertical machining center is simpler, the floor space is smaller, and the price is cheaper.
