Description

Vibration suppression type CNC machining center Technical Field The utility model relates to the technical field of processing machine tools, in particular to a vibration suppression type CNC processing center. Background Vibration problems generated in the CNC machining process are always key factors for limiting further improvement of machining quality. When the CNC machining center operates, high-frequency vibration is caused by cutting force between a cutter and a workpiece, and complex vibration response is generated by unbalanced force generated by high-speed rotation of a main shaft and inertial impact caused by rapid movement of a workbench. These vibrations not only can make the machined surface appear the vibration line, reduce surface roughness, can also cause the processing size deviation, seriously influence precision and uniformity of part. For some slender shaft parts or thin-wall parts, the vibration problem is particularly remarkable, and even the parts can be scrapped. In order to solve the vibration problem in CNC processing, the prior art is mainly improved in the following aspects that firstly, the rigidity and the natural frequency of a machine tool are improved by optimizing the structural design of the machine tool, but the requirements of the method on materials and manufacturing processes are high, the cost is remarkably increased, secondly, an active or passive vibration control technology is adopted, such as a vibration sensor and an actuator are arranged on the machine tool, vibration is restrained through a feedback control algorithm, but the technical system is complex, the reliability is low, and the method is effective only under specific working conditions, thirdly, the tool path planning and cutting parameters are improved, the fluctuation of cutting force is reduced, and the method is usually at the expense of processing efficiency. In addition, in the processing process of the traditional CNC processing center, the workpiece is usually clamped by a chuck only in a single end, and when the slender workpiece is processed by the clamping mode, the overhanging part of the workpiece is easy to generate bending vibration due to the action of cutting force, so that the processing precision is seriously affected. Although some auxiliary supporting devices exist in the market, most of the devices are structurally fixed, and cannot be flexibly adjusted according to the diameter and the length of a workpiece, so that the applicability is poor. In view of this, we propose a vibration-suppressed CNC machining center.
