CNC machining center is currently one of the world's highest output and most widely used CNC machine tools. CNC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and CNC system, which is suitable for processing complex parts.
The work center is often divided into a vertical machining center and a horizontal machining center according to the state of the spindle in the space. The spindle of the machining center in the space is called a vertical machining center, and the spindle in the space is called horizontal. Machining center. The spindle can be converted vertically and horizontally, which is called vertical and horizontal machining center or five-sided machining center, also called composite machining center. According to the number of columns in the machining center; there are single column type and double column type (gantry type).
According to the number of coordinates of the machining center movement and the number of coordinates simultaneously controlled: there are three-axis two-linkage, three-axis three-linkage, four-axis three-linkage, five-axis four-linkage, six-axis five-linkage, etc. The three-axis and four-axis refer to the number of motion coordinates possessed by the machining center, and the linkage refers to the coordinate number that the control system can control the motion at the same time, so as to realize the position and speed control of the tool relative to the workpiece.
According to the number and function of worktables: there are single workbench machining center, double workbench machining center, and multi-workbench machining center.
According to the processing accuracy: there are ordinary processing centers and high-precision processing centers. Ordinary machining center with a resolution of 1μm and a maximum feed rate of 15 ～
25m / min, positioning accuracy is about l0μm. High-precision machining center with a resolution of 0.1 μm, a maximum feed rate of 15 to 100 m / min, and a positioning accuracy of about 2 μm. Between 2 ～ 10μm, more than ± 5μm can be called precision grade.
Understand the classification of CNC machining centers, in order to better understand their uses, and then choose the right product, so these small knowledge can not be ignored.
