The factory uses precision CNC machine tools (machining centers, electric sparks, slow wires and other machine tools) for high precision treatment. is often not good enough; After long vacation, the machine will be launched to treat.
The factory without experience in precision machining often attributes the reason for this instability of precision to the quality problems of the equipment. The factory with experience in precision machining pays great attention to the thermal balance between ambient temperature and machine tools. They are very clear that even high-precision machine tools can only obtain stable treatment accuracy under a stable temperature environment and thermal balance. After starting the machine, you must invest in high precision treatment and production.
01
Why do you need to preheat the machine?
The thermal characteristics of CNC machine tools have a significant impact on the precision of machining, which represents almost half of the machining precision. The main tree of the machine tool, the guide rails, the screws and the other components used in the parts of the Xyz movement tree will warm up and deform due to the load and friction during movement, But the main tree and the XYZ motion rod parts which ultimately affect machining The accuracy of the thermal deformation error chain is the parents of the main tree and the parts of the Xyz movement tree.
The precision of treatment of the tool-machine when stopped for a long time and the thermal equilibrium state is very different. Run for a period of time.
However, the process of preparing machine tools is ignored or unknown to many factories.
02
How to preheat the machine tool?
If the tool-tool is interrupted for more than a few days, it is recommended to preheat for more than 30 minutes before high precision treatment; – Forecast process.
The preheating process is to allow the tool to participate in the repeated movement of the machining axis. of the coordinate system and repeatedly moving the diagonal line.
During the execution, you can write a macro program on the tooltip to allow the tool to carry out preheating actions on several occasions.
Once the machine-tool is fully preheated, the vibrant machine-tool can be put in high precision treatment and you will get stable and coherent treatment accuracy.
