In the machining process of CNC lathes, sometimes we may find that the actual size of the workpiece we process does not match the required size. If we force it to be machined in this way, it may cause damage to the workpiece, and in severe cases, it may also cause damage to the CNC lathe itself. Today, our CNC lathe manufacturer will explain to you the handling methods for the actual size of the workpiece that does not match the required size.
Cause of the problem: The speed of quick positioning is too fast, and the drive and motor cannot respond well; After prolonged conflict and wear, the mechanical drag plate screw and bearings are too tight and stuck; The knife holder is too loose and cannot be locked tightly after changing the knife; The corrected program error was completed without proper attention or revocation of the knife repair at the beginning and end; The electronic gear ratio or step angle of the system is set incorrectly.
Solution: If the fast positioning speed is too fast, adjust the speed of GO appropriately, adjust the cutting speed and timing to ensure that the driver and motor operate normally at additional operating frequencies; If the drag plate, screw and crane bearings become too tight and stuck after the machine tool wears out, it is necessary to readjust and correct them; If the tool holder is too loose after changing, check whether the tool holder is satisfied with the reversal time, whether the turbine worm inside the tool holder is worn, whether the gap is too large, and whether the device is too loose; If it is caused by program reasons, it is necessary to revise the program, improve according to the requirements of the workpiece drawing, select reasonable processing technology, and write the correct program according to the instructions in the manual; If the scale error is found to be too large, check whether the system parameters are set properly, especially whether the electronic gears and step angle parameters are damaged. This phenomenon can be measured by using a dial indicator.
The above is the solution provided by the CNC lathe manufacturer for the discrepancy between the actual size of the workpiece and the required size. We hope that the above explanation can be helpful for everyone in dealing with the inconsistency of workpiece size in the future.
