Heavy-duty V650 CNC machining center What does rigidity mean, and what is the specific parameter index? It is an index for comprehensive consideration of the machine tool. Generally speaking, it is the ability of the three major parts of the drive structure, moving parts, and bed structure to resist deformation, and the force load and dynamic load acting on the machining center. The production of these two forces proves that the quality of the machining center is not good enough, and it plays a vital role in the machining accuracy and service life of the machining center.
How to judge the rigidity of CNC machining center machine?
How to determine whether the rigidity of the machine tool is good or not when purchasing? Simply put, you can look at the maximum cutting parameters specified by the machine tool at the factory, such as the maximum tool engagement, the maximum cutting speed, and the maximum feed rate. The above parameters can be tested without exceeding the factory parameters of the machine. Then measure the actual dimensional accuracy of the workpiece, and see how much the deviation value deviates from the design accuracy of the machine tool to draw conclusions.
Of course, when choosing, is it right that the better the rigidity, the better the performance of the machine tool? Such judgments are not comprehensive. The current machining center machine tools on the market have different machines to achieve the purpose of production design. For example, if the purpose is to increase the processing speed, it is necessary to increase the spindle speed, with a small amount of knife, the rigidity is good, and it can be processed quickly; low-speed processing, the machine has good rigidity, and achieves heavy cutting.
The rigidity of the CNC machining center is mainly affected by the accuracy of the processed workpiece. There are a lot of researches on the rigidity of the machine tool at home and abroad. The rigidity of the machine tool should not only be considered to increase the rigidity of each component, but also the rigidity of the joint and each component. Matching problems between rigidities. Different components and joints have different contributions to the rigidity of the machining center. Reasonable allocation or optimization of rigidity should be carried out in the design to ensure that the CNC machining center can work normally for a long time.
