The plastic bottle cap mold processing error is caused by the original error in the process system. To improve the mold processing accuracy, the original error must be eliminated or reduced. There are many methods and measures to eliminate or reduce errors in production practice.
(1) Reduce machine tool errors and improve plastic bottle cap mold processing accuracy
1) Select a processing machine with good rigidity and high accuracy, and select a precision machine with spindle cooling, lead screw cooling, and thermal balance adjustment if possible. The closed-loop CNC system can remove the transmission error of the machine tool.
2) Reduce the influence of the heat source of the machine tool. Usually precision machining machine tools are placed in a constant temperature environment to make the machine work stably in a thermal equilibrium state.
(2) Reduce machining principle errors and improve plastic bottle cap mold processing accuracy In mechanical processing, rotary processing accuracy is usually higher than interpolation processing accuracy, so the round holes and shafts in the mold should be boring, turning or planet Grinding can effectively eliminate principle errors.
(3) Reduce the measurement error and improve the processing precision of plastic bottle cap molds In order to improve the adjustment accuracy, the tool setting microscope, optical measurement, electrical measurement and other instruments are often used in processing to adjust the relative position of the tool and the workpiece. When measuring and selecting a measuring tool, it should be based on the accuracy requirements of the workpiece, so that the limit measurement error of the selected measuring tool is within the range of 1/10 to 1/3 of the workpiece tolerance. During the measurement, the temperature difference between the measuring tool and the workpiece to be measured should be minimized. For the measurement of precision parts, it should be performed under the corresponding constant temperature conditions.
