How high is the machining precision of the CNC machine and how to calculate it?
The first step is to study how to improve the accuracy of CNC lathe machining from the aspect of mechanical adjustment. The adjustment of the machine tool mainly includes these parts, such as the spindle, the bed and the inserts, etc., so that the lathe can meet the requirements and improve the machining accuracy of the CNC lathe. It must be monitored in real time during the work process and continuously optimized. Insufficiency in the lathe, in order to timely adjust the production site for better products. This is the simplest and most convenient way to improve the machining accuracy of CNC lathes. This adjustment method does not require very good skills, but requires employees to check from time to time to make adjustments.
The second step is the improvement in the electromechanical joint debugging. To improve the machining accuracy of the parts, it is mainly to improve the reverse deviation, positioning accuracy and repeat positioning accuracy. In terms of reverse deviation, when the deviation is too large, we must first correct it by mechanical and manual methods, and then use professional methods to further optimize when the error is within a certain range. In the adjustment of positioning accuracy, the error is continuously optimized through the degree of the microscope. The electromechanical joint adjustment method optimized in these aspects is the most efficient method among these adjustment methods. Although it will be more cumbersome but the effect is better.
The third step is through electrical adjustments. The adjustments in this area mainly include two aspects. One is the adjustment of machine tool parameters. In this angle, there are two aspects that affect the machining accuracy is the system gain and To locate the dead zone, in terms of system gain, we must pay attention to the mechanical damping of the lathe and the moment of inertia, which all affect the accuracy of the lathe's processing. There is also to minimize the dead zone of positioning, which can also improve the accuracy of the lathe during operation. These two aspects are complementary and must be adjusted at the same time. Another aspect is that it can be adjusted through the application of some systems. Due to the continuous improvement of automation, CNC lathes use automatic remote control during operation, so we need to enter a series of real-time monitoring during remote control. In this way, there is no need for excessive manual intervention, so that it can be supervised more effectively, and the control setting can be supervised through the program, and then the accuracy of the lathe processing can be improved.
