Ball nut is a kind of high-precision mechanical parts, which is widely used in various mechanical equipment, including CNC machine tools, precision bearing seats, ball screws, etc. As an important component of the feed system in CNC machine tools, the maintenance method has an important impact on the accuracy and service life of machine tools.
Ball nut is a kind of high-precision mechanical parts, which is widely used in various mechanical equipment, including CNC machine tools, precision bearing seats, ball screws, etc. As an important component of the feed system in CNC machine tools, the maintenance method has an important impact on the accuracy and service life of machine tools. The following are several suggestions for the maintenance of ball nuts of CNC machine tools:
1. Cleaning and lubrication: Clean the outside and inside of the ball nut regularly to remove dust and impurities. At the same time, it is necessary to add an appropriate amount of lubricant to the ball nut regularly to reduce friction and wear.
2. Inspection and fastening: Regularly check the fasteners of the ball nut to ensure that the matching clearance between the nut and the screw is appropriate to avoid loosening or overtightening. If loose fasteners are found, they should be tightened in time to avoid further damage.
3. Check the screw: regularly check the screw surface of the ball nut to ensure that it is smooth and has no obvious wear or corrosion. If there is an abnormal situation, the screw should be replaced in time to avoid affecting the performance of the entire transmission system.
4. Axial clearance inspection and adjustment: check the axial clearance of ball screw nut pairs of CNC machine tools regularly. Under normal circumstances, the clearance can be eliminated by active compensation of the control system. When the gap is too large, you can adjust the ball screw nut to ensure its accuracy.
5. Inspection of screw rod protective cover: check the screw rod protective cover regularly to avoid dust and abrasive particles sticking to the surface of the screw rod and affecting the service life and accuracy of the screw rod. If it is found that the protective cover of the screw rod of the CNC machine tool is damaged, it shall be repaired and replaced in time.
6. Support bearing inspection: regularly check whether the connection between the support bearing of the numerical control machine tool and the machine tool is loose, and whether the support bearing is damaged, etc. If so, tighten the loose part in time and replace the support bearing.
