Control of machining accuracy of CNC lathe in production
The influence of CNC lathe machining accuracy is generally caused by the following several reasons, one is the equipment reason, the second is the tool problem, the third is programming, the fourth is the benchmark error, today Wally machinery technology and you briefly describe these aspects.
1. The machining accuracy of CNC lathe caused by equipment is generally caused by the system error of the machine itself and the error caused by the runout of the machine tool. In the process of using the machine tool, the core parts such as the lead screw are worn, resulting in the increase of the gap, and the greater the error of the machine tool, which will affect the machining accuracy of the CNC lathe;
2. In the process of NC lathe processing, it is very important to select the cutting tool. Unsuitable tool will lead to too high machine load and tool wear too fast, which will lead to the CNC lathe precision can not meet the product requirements;
3. The unreasonable cutting parameters set during programming is also one of the reasons that the machining accuracy of CNC lathe can not be guaranteed. The cutting parameters of feed and revolution must be set by combining the tool, material characteristics and equipment, so as to ensure the machining accuracy of CNC lathe;
4. In the process of NC lathe processing, the datum error of products is also one of the reasons that the machining accuracy of CNC lathe can not meet the requirements. Through the combination of turning and milling, the clamping times can be reduced as much as possible, which can reduce the influence of secondary processing on the machining accuracy of CNC lathe caused by the change of datum.
The above content is volley machinery technology for everyone to share on the topic of CNC lathe machining accuracy, hope to give CNC machining people to reference.
