Analysis of CNC Machine Tool Errors and Causes
In order to improve the machining accuracy of CNC machine tools, technicians must carry out a detailed analysis of the errors generated during the NC machining process, find out the causes of the machining errors, and take corresponding measures in time to reduce production losses. The following small editors have collated the machining errors and causes of CNC lathes and high-precision CNC machine tools:
Analysis of CNC Machine Tool Errors and Causes
1. CNC machining machine 1, CNC machine tool error caused by its own processing error: control system error; machine tool feed transmission system error 2, the manufacturing process caused by the processing error: processing process arrangement is not reasonable; tool cut-out point selection inappropriate 3, the workpiece Errors resulting from positioning 4. Errors caused by irrational programming 2. High-precision numerically-controlled machine tool 1. High-precision CNC lathe out of the car. The outer circle is a cone: the connection between the front and rear tops is not coaxial with the axis of the spindle. It is the end of the CNC lathe. Block center is not caused.
2. Vibration generated by the workpiece during turning of the CNC machine tool: it may be that the tailstock sleeve is extended too long or the workpiece top is too loose. It may be that the turning tool is not sharp enough or the arc of the cutting edge is too large, or the bearing clearance of the turning top is large. Or the gap between the medium and small skateboards is too big.
3, the circle can not meet the requirements: the top of the shaft has been with the axis of the spindle or the rotation of the top bearing wear caused by the circular runout, the center hole of the workpiece is not clean or the center hole collision hair, Ji Xin head of the card touch card The end face of the disc does not function as the center hole. 4. The center hole of the high-precision CNC lathe is severely worn or bitten: It may be that the fixed tip is not lubricated or the spindle speed is too high, or the pliers are not clamped when turning. The workpiece has stopped rotating.
The source of error when using CNC machined parts is very complex. Only by properly grasping the principle of CNC machine tools and strengthening the process knowledge of operators can we solve the problem of machining error of CNC machine tools and improve the accuracy of CNC machining to produce qualified products. product.
