Каковы общие классификации обрабатывающих центров?
1) CNC Vertical machining center
Vertical machining center refers to a machining center with a vertical spindle, as shown in the figure. Its structure is mostly a fixed column. The worktable is rectangular and has no indexing and rotation function. It is suitable for processing discs, sleeves and plate parts. It generally has two linear motion coordinate axes, and one can be installed on the worktable along the horizontal axis. Rotating turntable is used to process spiral parts.
The vertical machining center is easy to install, easy to operate, easy to observe the processing conditions, easy to debug the program, and has a wide range of applications. However, limited by the height of the column and the tool changer, parts that are too high cannot be machined. When machining the cavity or concave profile, the chips are not easy to discharge. In severe cases, the tool will be damaged, the machined surface will be damaged, and the smooth processing will be affected. .
2) Horizontal CNC machining center
Horizontal machining center refers to a machining center with a horizontal spindle, as shown in the figure. Horizontal machining centers usually have an automatic indexing rotary table, which generally has 3 to 5 motion coordinates. The common one is three linear motion coordinates plus one rotary motion coordinate. After the workpiece is installed once, the installation is completed. It is most suitable for the processing of the other four surfaces except the top surface and the top surface. Compared with the vertical machining center, the horizontal machining center is easy to remove chips during machining, which is beneficial to the machining, but the structure is complicated. The price is higher.
3) Gantry CNC machining center
The shape of the gantry machining center is similar to the CNC gantry milling machine, as shown in the figure. The main spindle of the gantry machining center is mostly vertical. In addition to the automatic tool change device, it also has a replaceable spindle head attachment. The CNC device has complete functions and can be used in one machine. It is especially suitable for processing large workpieces and complex shapes. Artifact
4) Five-axis CNC machining center
The five-axis machining center has the functions of a vertical machining center and a horizontal machining center, as shown in the figure. Five-axis machining center, after the workpiece is installed once, it can complete the processing of the other five surfaces except the installation surface. Common five-axis machining centers have two forms: one is that the spindle can be rotated to perform vertical and horizontal machining of the workpiece; the other is that the spindle does not change the direction, but the worktable rotates with the workpiece. , Finish the processing of the five surfaces of the workpiece.
5) Multi-axis CNC machining center
The multi-axis machining center has changed the structure of the traditional machine tool in the past. Through the movement of the connecting rod, the movement of the spindle with multiple degrees of freedom is realized, and the processing of the complex curved surface of the workpiece is completed.
