Introduce The Method Of Reducing The Tool Error Of CNC Busbar Processing Machine

When the CNC busbar processing machine realizes the punching, cutting and bending operations, the error is unavoidable. The error is an important factor affecting the machining accuracy of the CNC busbar processing machine. In order to improve the processing accuracy, we must take measures to minimize the error. Small measures. Here is a brief way to reduce the error:
1. The influence of tool error. On the machining center, because the tool used has the function of automatic exchange, while improving productivity, it also brings tool exchange error. When processing a batch of workpieces with the same tool, due to frequent repeated changes The tool will cause the tool holder to produce repeated positioning errors relative to the spindle taper hole and reduce the machining accuracy.
2. The influence of repeated positioning accuracy of the machine tool. The positioning accuracy of the CNC busbar processing machine refers to the position accuracy of the coordinate axes of the CNC machine tool moving under the control of the system. The factors that cause positioning errors include system errors and mechanical transmission errors. The error of the system is related to interpolation error, tracking error, etc. The repeated positioning accuracy of CNC busbar processing machine refers to the degree of conformity between the actual position of the coordinate axis and the ideal position during repeated positioning.
3. The influence of the detection device. The detection feedback device is also called the feedback element, which is usually installed on the worktable or screw of the CNC busbar processing machine. The detection feedback device converts the displacement of the worktable into an electrical signal and feeds it back to the numerical control device. If there is an error compared with the command value, the control table moves in the direction of eliminating the error. The numerical control system can be divided into open-loop, closed-loop and semi-closed-loop systems according to whether there is a detection device. The accuracy of the open-loop system depends on the stepping motor and the lead screw. Accuracy, the accuracy of the closed-loop system depends on the accuracy of the detection device. The detection device is an important part of the high-performance CNC busbar processing machine.
