What should we linear guide to make machine tool?
Time:2021-01-26
When designing and manufacturing machine tools, we need to pay attention to the following problems:
1. The machine tool has high anti vibration performance. The machine tool with linear rolling guide is easy to produce vibration. The high-speed advance and retreat of moving parts will make the machine bed suffer huge impact, which will lead to the shape error and ripple on the machined surface. Especially in the grinder and high-precision machine tool, the influence is more obvious, and the closed-loop servo control will also lead to the instability of the system.
2. The vibration model of machine tool with linear rolling guide is similar to that of undamped forced vibration. The maximum amplitude of machine tool can be reduced by reducing the mass of moving parts, increasing the mass of machine tool body and increasing the static rigidity of machine tool. However, the method of increasing the weight of machine tool body is usually less, because increasing the mass of machine tool body will reduce the natural frequency of machine tool and lead to the deviation of resonance frequency of machine tool So it is not helpful to improve the anti vibration performance of the machine tool simply by increasing the wall thickness to improve the rigidity of the machine tool.
