What is a Vertical Machining Center ?

Introduction of vertical machining center
The structure of CNC vertical machining center refers to the machining center with the spindle and workbench in a vertical state. The vertical machining center integrates the characteristics and functions of various CNC machine tools. The vertical machining center is developed from the basic CNC milling machine, and it also integrates the features and functions of the CNC milling machine. Its structure is basically the same, and its 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 changing device and tool magazine, but the CNC milling machine does not have this function. The vertical machining center can complete milling, boring, drilling, tapping, tapping and other processes by clamping the workpiece once, and the vertical machining center can at least realize three-axis and two-linkage, the general vertical machining center can realize three-axis and three-linkage, and some can control five-axis and six-axis. The more axes are controlled, the wider the machining range will be.

Advantages of Vertical Machining Center
1. Because of the simple structure of the vertical machining center, it is very easy to clamp the workpiece. Universal clamps, such as flat pliers, pressing plates, indexing heads, rotary table and other clamps, can be used to clamp the workpiece. The clamping, positioning and repeated positioning of the workpiece are very convenient and simple.
2. The structural design of the vertical machining center is conducive to cooling, because the coolant is sprayed from top to bottom and can be directly sprayed onto the high-temperature workpieces and tools during machining.
3. The structure of vertical machining center is relatively simple, it can observe the running track of cutting tools, and it is also convenient to debug, observe and modify parameters, and it is also convenient to measure workpieces. When problems are found, it will stop immediately for processing and modification.
4. The vertical machining center is easy to remove chips when machining planar workpieces, and the generated chips are directly washed away by the sprayed cooling liquid, thus avoiding the chips from scratching the surface of workpieces during cutting.
5.Compared with horizontal machining center, the structure of vertical machining center is simpler, the floor space is smaller, and the price is cheaper.

Disadvantages of Vertical Machining Center
1. Because the spindle of the vertical machining center is parallel to the workbench, the workpiece to be machined has a certain height limit. Not only that, but also the size limit of the fixture and cutter, and the manipulator needs to occupy a lot of space when changing the cutter.
2. From the above shortcomings, the possibility of vertical machining of box-shaped workpieces in center is small, and the range of machining box-shaped workpieces is relatively small. This is also one of the disadvantages of vertical machining centers.

Pay attention to vertical milling machine operation as follows
1. Before using the vertical milling machine, it must be carefully checked according to the patrol checkpoint, and lubricated according to the lubrication chart.
2. If you stop using the vertical milling machine for more than eight hours before starting the equipment, you should rotate it at a low speed for three to five minutes, and then start working after confirming that the lubrication system is unobstructed and the parts move normally.
3. During the use of the milling machine, you are not allowed to leave or entrust others to take care of it. You are not allowed to remove the safety protection device, and you are not allowed to remove the following gear iron.
4. If the vertical milling machine should be maintained, the beam spindle workbench and lifting platform should be loosened before moving, the surrounding sundries should be removed, and then the guide rails and oil should be wiped.
5. When the milling machine feeds quickly or automatically, the limit stop should be adjusted first.
6. Always check the operation and lubrication of equipment and various parts in the work. Such as poor operation or lubrication, should stop using.
7. Work, card measuring tools and workpieces are forbidden on the workbench.
8. When adjusting the automatic cycle, you must check the correctness of the automatic cycle of the machine tool before starting.
9. When the work is finished, put the handles of the vertical milling machine in the non-working position, put the workbench in the middle position, and cut off the power supply when the lifting platform falls below.
