Cause and elimination method of surface vibration waviness in turning machining
Vibration waviness is caused by various reasons in mechanical machining, which makes the machining surface of the lathe tool and the workpiece wavy. The appearance of vibration waviness has a certain influence on the machining quality, machining accuracy and some performance of the workpiece surface.
The vibration waviness in the process of turning machining come from the internal of the machine tool and the outside of the machine tool. The internal parts of machine tools include the imbalance caused by the defective parts of the rotating parts on machine tools, the unstability of the belt driving mechanism of machine tools, the impact force of the reciprocating mechanism and the change of cutting force during machining. The vibration waviness comes from outside of the machine tool is to mainly refer to the large equipment near the machine tool through the foundation transmitted to the machine, or the infirmness of the foundation of the lathe itself.
Therefore, to solve the problem of vibration waviness on the surface of the turning machining workpiece, we should be familiar with the performance of various mechanism of the machine tool, understand the status of parts of machine parts,, so that we can find out the problems and solve the problems quicker through various shapes of chatter, so as to eliminate or reduce the appearance of vibration waviness.
