What are the causes of vibration marks in VMC1160CNC machining center?
1, the CNC machining center itself: there are more factors affecting the machine tool, but mainly due to local or insufficient rigidity of the system, there are abnormal vibration sources caused by machine tool system vibration. Machine vibration leads to vibration marks (mostly straight vibration marks or porphyritic marks) on the inner surface of the workpiece.
- Cutting fluid: the coolant used by the CNC machining center manufacturer should be suitable for high-speed cutting, not mixed with granular impurities, otherwise it should be replaced; Coolant flow and pressure should be stable and sufficient; Processing center manufacturers should regularly check the coolant filtration, slag discharge and cooling pump working conditions, found problems solved in time.
- Workpiece: uneven cutting allowance of machined workpiece causes excessive cutting amount of individual; The workpiece itself or the fixed rigidity of the workpiece, such as some small and thin parts that cannot be fully fixed with reasonable fixtures due to their own lack of rigidity, or due to the shape of the workpiece, will produce straight vibration lines or oblique vibration lines on the inner surface of the workpiece, and the accuracy will be out of tolerance.
- CNC machining center system and the rigidity of the driver does not match and other reasons, will produce vibration marks.
- The influence of the machine spindle system: the rigidity of the machine spindle itself, the performance of bearings and gears, as well as the connection rigidity between the spindle and the shank is unreasonable will lead to the vibration marks of the workpiece.
According to the analysis of Tsinfa CNC Co., LTD., there are many reasons for the vibration pattern of the workpiece, but it is nothing more than a comprehensive machining center itself, machine configuration, machining workpiece and cutting fluid problems. When buying CNC machining centers, we must choose high-quality manufacturers
