Ball screws are the core of CNC machine tools for high efficiency and precision. Regular lubrication, inspection and maintenance, proper selection, protection and cleaning and standardized operation can significantly reduce friction and improve precision and life.
Reducing the coefficient of friction is a must for CNC machine tools that require high and stable machining accuracy over time, as well as having a lower transmission resistance while laying the foundation for higher speed transmission. The use of ball screws is also an important reason for the high machining efficiency of CNC machine tools. In order to reduce the friction of ball screws in CNC machine tools, the following measures can be taken:
1, lubrication: ball screw in a good lubrication friction influence coefficient is very low, not only can reduce friction and wear and tear, but also effectively control the temperature to prevent overheating. Therefore, it is necessary to check the quality and quantity of lubricant regularly and replace the oil in time to keep the effectiveness of the lubrication system.
2、Regular inspection and maintenance: Regularly check the operation of the ball screw, including loosening, wear and tear, damage, etc., and repair or replace it in time to ensure the stability and reliability of the CNC machine tool.
3、appropriate selection and avoid overloading: according to the working load of CNC machine tools, speed requirements and accuracy requirements and other factors, select the appropriate type and specification of the ball screw to ensure that it can meet the working requirements of the machine tool. At the same time, the ball screw should avoid overloading in the work, otherwise it may lead to the damage or premature wear of the ball screw, affecting the normal operation of the CNC machine tool.
4、Protective measures: ball screw protective measures are also very important, in order to avoid this frictional resistance, you can use more rigid plastic made of non-contact labyrinth seal.
5、Cleaning and protection: Regularly remove the screw surface dust, oil and impurities, to avoid wear and corrosion caused by these contaminants on the screw. For the exposed part of the screw, should be installed protective cover or protective plate and other protective devices to prevent dust, iron filings and other foreign objects from entering the interior of the screw.、
6、Operation specification: When using ball screws, the operation specification should be observed to avoid improper operation such as over-traveling use and over-speed operation, which will accelerate the wear and tear, reduce the performance, and even lead to the damage of the equipment.
In order to reduce the friction coefficient of the ball screw, the above measures are very critical, which not only help to improve the precision and efficiency of the equipment, but also extend the service life of the equipment. If there are other questions welcome to contact us for consultation.
