CNC machining center common classification and CNC machining tool clamping principles

Not familiar with CNC machining center friends will think that it is only one, in fact, it is not, CNC machining center has a lot of classification, of course, according to different situations have different dividing principle, next to tell you about the common CNC machining center classification?

1, according to the state of the main axis in space.

Divided into vertical machining center and horizontal machining center, machining center of the spindle in the vertical state in space is called the vertical machining center, the spindle in the horizontal state in space is called the horizontal machining center. The spindle can be made of vertical and horizontal conversion, known as the vertical horizontal processing center or five processing center, also known as the composite processing center. According to the number of machining center column points; There are single column and double column.

2. According to the number of moving coordinates of the machining center and the number of coordinates controlled at the same time

There are three axis two linkage, three axis three linkage, four axis three linkage, five axis four linkage, six axis five linkage, etc. Three axes and four axes refer to the number of moving coordinates of the machining center. Linkage refers to the number of moving coordinates that can be controlled by the control system at the same time, so as to realize the position and speed control of the tool relative to the workpiece.

3, according to the number and function of the workbench

There are single working table processing center, double working table processing center, and multi working table processing center.

4, according to the processing accuracy

There are ordinary machining center and high precision machining center. Ordinary machining center, resolution of 1μm, the maximum feed speed of 15-25 m/min, positioning accuracy of about L0 μm. High precision machining center, resolution of 0.1μm, the maximum feed speed of 15-100m /min, positioning accuracy of about 2μm. Between 2 - L 0μm, with more than ±5μm, can be called precision.

Through the introduction of this industry knowledge, we also have an understanding of the classification of CNC machining center, tool is an important part of CNC machining center, tool clamping problem affects the quality of the workpiece, so in the processing process of tool clamping pay attention to what principle?

1. All the clips are horizontal long and vertical short.

2, vise clamping: the clamping height should not be less than 10 mm, in the processing of the workpiece must indicate the clamping height and processing height. Processing height should be about 5 mm higher than the vice plane, the purpose is to ensure firmness, while not hurting the vice. This kind of clamping is a general clamping, clamping height is also related to the size of the workpiece, the larger the workpiece, the clamping height increases accordingly.

3, splint clamping: splint with code code on the workbench, the workpiece is locked on the splint with screws, this clamping is suitable for clamping height is not enough and the processing force is large workpiece, generally medium and large workpiece, the effect is better.

4. Code iron clamping: when the workpiece is large, the clamping height is not enough, and the silk is not allowed to lock at the bottom, the code iron clamping is used. This kind of clamping needs two clamping, first code good four corners, processing other parts, and then code four sides, processing four corners. Second clamping, do not let the workpiece loose, first code and then loose. You can also code both sides, processing the other two sides.

5, tool clamping: diameter of more than 10mm, clamping length is not less than 30mm; Diameter less than 10mm, the clamping length is not less than 20mm. The clamping of the tool should be firm, to prevent the collision of the knife and directly inserted into the workpiece.
