Types of vibration that Swiss type CNC lathes receive
There are many obvious abnormalities in Swiss type CNC lathes. In some economical CNC systems, there is no alarm. Even if an alarm occurs sometimes, the alarm message indicates that it is not an alarm that you see abnormal. Creeping and vibration of machine tools are obvious examples. When the CNC lathe is running at a low speed, the machine tool table moves forwards peristally; when the machine tool is running at a high speed, vibration occurs.
The vibration classification of Swiss type CNC lathes generally has two main categories, forced vibration and self-excited vibration. On CNC lathes, milling machines and grinders, forced vibration of the rotary spindle system is often seen, and its frequency depends on the speed of the rotary spindle system. There are many types of self-excited vibration that occur on machine tools, and the system's torsional or bending self-excited vibration;
Bending or torsional self-excited vibration of the machine bed, column, beam and other supporting parts; there are also relaxation friction self-excited vibration (commonly known as creeping) that occurs when moving parts such as worktables are running at low speed. This type of self-excited vibration that is manifested as a strong relative vibration between the tool and the workpiece during metal cutting is commonly referred to as flutter.
