There are many types of machining centers, which can be divided into different types according to different classification methods:
1. According to the state of the spindle in the space
(1) Vertical machining center: The spindle of the machining center is in a vertical state in space.
(2) Horizontal machining center: the spindle is in a horizontal state in space.
(3) Vertical and horizontal machining center: the spindle can be converted vertically and horizontally, also known as five-sided machining center and compound machining center.
2. According to the number of machining center columns
It can be divided into single-column machining center and double-column (gantry) machining center.
3. According to the number of motion coordinates of the machining center and the number of coordinates controlled at the same time
It can be divided into three-axis two-linkage, three-axis three-linkage, four-axis three-linkage, five-axis four-linkage, six-axis five-linkage, etc. Three-axis and four-axis refer to the number of motion coordinates that the machining center has, and linkage refers to the number of coordinates that the control system can control at the same time, so as to realize the position and speed control of the tool relative to the workpiece.
4. According to the number and function of the workbench
There are three types: single-table machining center, double-table machining center and multi-table machining center.
5. According to the processing accuracy
(1) Ordinary machining center: the resolution is 1μm, the maximum feed speed is 15~25m/min, and the positioning accuracy is about l0μm.
(2) High-precision machining center: the resolution is 0.1μm, the maximum feed speed is 15~100m/min, and the positioning accuracy is about 2μm.
