What are the characteristics of the vertical machining center
The vertical machining center refers to the machining center with the main shaft in a vertical state. Its structure is mostly fixed columns, the workbench is rectangular, and has no indexing and rotating functions. It is suitable for complex processing of plates, discs, molds and small shells. Component. The vertical machining center can complete the processes of milling, boring, drilling, tapping and thread cutting. It generally has three linear motion coordinate axes, and a rotary table that rotates along the horizontal axis can be installed on the worktable to process spiral parts, and can process 5 degrees of freedom.
The vertical machining center has the following main functional characteristics:
1. Automatic tool change function
The structure of the vertical machining center and the CNC milling machine are basically the same, and the processing technology is basically similar, but the biggest difference between the two is that the machining center replaces the automatic tool changer and tool magazine, and the CNC milling machine does not have this function. The vertical machining center with automatic tool changer and tool magazine has an automatic tool change function, which can be replaced according to the tools used in processing. Generally speaking, the vertical machining center can change the tool at will to process different processes of the workpiece.
2. One-time workpiece clamping can process multiple processes
From the previous function point, the vertical machining center has an automatic tool change function. With this function, it can perform multi-process processing in one clamping process, such as boring, drilling, milling, tapping and tapping. processing.
3. The function of expanding the number of axes
Since the conventional three-axis machining center cannot meet the customer's product processing requirements, such as processing complex curved surface workpieces such as impellers, blades, shafts, propellers, etc., the three-axis vertical machining center cannot be processed, so the four-axis is expanded according to the customer's product requirements. Or five-axis function. From the above, we know that the vertical machining center has the function of expanding the number of axes, and can expand the functions of four-axis, five-axis and multi-axis.
4. One workpiece clamping can process multiple processing surfaces
It is known from the above that the vertical machining center can expand the number of axes, so after the vertical machining center expands the number of axes, the workpiece can be clamped and processed with multiple processing surfaces. The accuracy error caused by multiple clamping is avoided, and the time for manually clamping the workpiece is also saved.
