China CNC automatic drilling and tapping machines are more and more widely used in the industrial field, but during long-term operation, due to heat accumulation and conduction, thermal deformation problems sometimes occur. This situation will not only reduce the accuracy and stability of the drilling and tapping machine, but may also affect the processing quality and efficiency. Therefore, it is very important to reduce the thermal deformation of the CNC automatic drilling and tapping machine. This article will introduce some methods to reduce thermal deformation. Thermal deformation is mainly caused by the heating of the drilling machine during operation. Therefore, to reduce thermal deformation, it is first necessary to reduce the operating temperature of the CNC automatic drilling and tapping machine. Here are a few things to try:
1. Optimize the lubrication system: A suitable lubrication system can reduce the friction between the parts of the CNC automatic drilling and tapping machine, thereby reducing the generation and accumulation of heat. Ensure stable and uniform oil supply of the lubrication system, which can effectively reduce thermal deformation.
2. Improve the effect of the cooling system: Consider increasing the cooling system of the CNC automatic drilling and tapping machine to discharge heat from the machine tool more quickly. Cooling devices can be installed around the main shaft, guide rails and main heat source to avoid heat accumulation and conduction.
3. Reasonable selection of materials: choosing materials with low thermal expansion coefficient and good thermal conductivity can reduce the thermal deformation of the drilling machine. For example, alloy materials with high thermal conductivity can be selected to help dissipate heat quickly.
4. Consider heating analysis: Use finite element analysis and other methods to conduct heating analysis on CNC automatic drilling and tapping machines to understand the possible thermal deformation during the heating process. Through this analysis, it is possible to determine which parts are more susceptible to thermal deformation and take targeted measures to improve them.
In addition to the above methods, there are some more detailed operations that can help reduce the thermal deformation of CNC automatic drilling and tapping machines:
1. Control cutting time: Reducing cutting time can reduce heat accumulation. Reasonably set cutting parameters to avoid excessively long cutting operations.
2. Regular maintenance and maintenance: regular maintenance of the drilling machine, including cleaning, lubrication, inspection of parts, etc., can keep the drilling machine in good condition and reduce the occurrence of thermal deformation. In general, reducing the thermal deformation of CNC automatic drilling and tapping machines is a comprehensive problem that needs to be considered and improved from many aspects. Optimizing the lubrication system, improving the effect of the cooling system, selecting reasonable materials and conducting heating analysis are all effective means to reduce thermal deformation. In addition, reasonable control of cutting time and regular maintenance of CNC automatic drilling and tapping machines are also important measures. Through the comprehensive application of these methods, the thermal deformation of the CNC automatic drilling and tapping machine can be effectively reduced, and the processing efficiency and quality can be improved.
