CNC turning and milling compound machine tool is a main type of compound machining machine tool. In addition to the functions of CNC lathes, it can also complete plane milling, drilling, tapping, straight groove, spiral groove and tooth milling, etc. The composite functions such as boring can realize the processing concept of one clamping and finishing.
Structural characteristics:
1. Reasonable layout, spacious interior space.
2. High-precision sleeve-type independent spindle structure, high-speed hydraulic rotary system.
3. Ensure the high speed of the machine tool.
4. The value of the servo motor will not cause errors due to power failure.
Second, the general CNC machine tools have the following two characteristics:
1. The spindle motor adopts servo motor, and the rotation motion of the spindle can be linked with the feed motion.
2. In addition to configuring the turret tool rest of the CNC lathe, at least configure the power tool, or configure an independent power tool rest.
Compared with ordinary machine tools, turning and milling has the following advantages:
1. A variety of special tools can be installed, and the new tool arrangement can reduce tool change time and improve processing efficiency. It can complete all or most of the processing procedures in one clamping, thereby shortening the product manufacturing process chain. In this way, on the one hand, the production auxiliary time caused by the change of the loading card is reduced, and at the same time, the manufacturing cycle and waiting time of the tooling and fixture are also reduced, which can significantly improve the production efficiency.
2. It has the function of online detection, which can realize the in-situ detection and precision control of key data in the manufacturing process, thereby improving the machining accuracy of the product; the high-strength integrated bed design improves the gravity machining capability of difficult-to-cut materials.
3. During turning and milling, the tool performs intermittent cutting. For workpieces formed of any material, a relatively short cutting can be obtained, which is easy to automatically remove chips, and the intermittent chips can allow the tool to have sufficient time to cool down and reduce the thermal deformation of the workpiece. It can also increase the service life of the tool. Compared with traditional CNC machine tools, turning and milling has a higher speed, better quality of the cut products, and reduces the cutting force, improves the precision of thin-walled rods and slender rods, and the workpiece forming quality is high.
