With the development of technology, machining centers have become the main force of processing, and more and more machining centers have become essential equipment for production. Machining centers are not affected by human factors, have good processing consistency, reduce labor intensity of workers, and become effective tools to improve production efficiency and process complex parts. Therefore, the machining accuracy of machining centers has become a common concern for everyone, Now let's analyze the factors that affect machining accuracy and make a summary. In practical use, everyone should try to avoid:
1. Screw clearance in the machining center: The positioning accuracy of the machining center directly affects the machining accuracy of the workpiece, and temperature has an important impact on positioning accuracy. If there is no machine tool in a constant temperature workshop, the machine tool should be run empty every day before processing, so that the temperature of the machine tool is consistent with the external temperature. During processing, we commonly refer to it as a hot machine, and the reverse clearance of the screw should also be regularly checked.
2. Level of Machine Tool: The level of CNC machine tools is also an important indicator that affects the accuracy of machine tools, so machine tools should be checked and adjusted regularly. Nowadays, most machine tools are castings, and adjusting the level is also a means to prevent machine tool deformation.
3. Spindle: The taper hole of the spindle is used to install the tool, and the accuracy of the taper of the taper hole and tool holder is also an important link to ensure machining accuracy.
4. Tools: The quality of the tools in the machining center is a crucial factor that directly affects the machining accuracy, and the lifespan of the tools determines the machining accuracy.
5. Errors in measurement and fixture positioning can also affect machining accuracy.
The impact of chip fluid: Many machine tool users do not attach importance to chip fluid and believe that only cooling the tool is sufficient. However, this is not the case, as will be explained in detail in future explanations.
