high speed machining centers

Industrial production is inseparable from high-speed machining centers. High-speed machining centers can realize continuous, efficient, and high-precision machining of multiple surfaces, multiple features, and multiple stations after one clamping. That is, the process is concentrated, and the spindle has advanced high precision and high rigidity. The design adopts the special bearing for the precision spindle, and the front three and the rear two high-rigidity spindle system parts can be selected for processing. So what are the characteristics of high-speed machining center processing?

1. High degree of flexible processing. When machining workpieces in a high-speed machining center, as long as the program is well prepared, there is no need to manufacture or replace many tools and fixtures, generally do not require very complex process equipment, and do not need to adjust the machine tool frequently, you can process workpieces with complex shapes and high precision. It greatly shortens the product development cycle and provides convenience for product upgrading and new product development.

2. High degree of automation. The machining process of the CNC machine tool is controlled by the CNC system, and there is no need to manually operate the machine tool during the machining process, which improves the working conditions.

3. The process is highly concentrated. After the high-speed machining center is clamped at one time, almost all the machining processes of the parts can be completed, which reduces the clamping error and saves auxiliary time such as turnover transportation, measurement and clamping between processes.

4. The processing quality is stable. Since the high-speed machining center itself has high repeat positioning accuracy, the machining process is controlled by the numerical control system according to the machining program, avoiding human errors, so the machining quality is stable and the product qualification rate is high.

5. High machining accuracy. The high-speed machining center itself has high positioning accuracy, and the transmission system of the machine tool and the structure of the machine tool have high rigidity and thermal stability.

6. High productivity. Since the high-speed machining center has good rigidity, it allows strong cutting, the spindle speed and feed range are large, and the cutting amount can be selected more reasonably, and the idle stroke adopts rapid feed, which saves the time of maneuvering and idle stroke.

In conclusion

High-speed machining center means that the spindle speed and displacement speed are faster than ordinary machining centers. Generally, the spindle speed must reach 10000rpm and the rapid displacement speed of 36M or more can be called a high-speed machining center.

The spindle speed of ordinary machining centers is generally 8000rpm, and there are even high-speed machining centers with spindle speed of 20000rpm and displacement of 48M. The higher the speed of the high-speed machining center, the higher the technical content of the machine tool, because the high speed brings high heat, so the high-speed machining center has a high demand for the structure of the machine tool.

The high-speed machining center has a fast cutting speed, so that the processing efficiency is high, the finish is good, and the workpiece is less deformed by the cutting force. It is suitable for cutting thin-walled parts and is widely used in aerospace, military, medical equipment and other fields.
