Methods to improve machining accuracy
01 Adjust the process system
1) Adjustment by trial cutting method
Try to cut - measure the size - adjust the tool's cutting amount - cut with the tool - try to cut again and again until the required size is reached. This method has low production efficiency and is mainly used for single piece small batch production.
2) Adjustment method
The required dimensions are obtained by pre adjusting the relative positions of the machine tool, fixture, workpiece and cutter. This method has high productivity and is mainly used for mass production.
02 Reduce machine error
1) To improve the manufacturing accuracy of the spindle components, the rotary accuracy of the bearing should be improved:
① High precision rolling bearing shall be selected;
② Adopt high-precision multi oil wedge dynamic pressure bearing;
③ High precision hydrostatic bearing is adopted,
The accuracy of accessories related to bearings shall be improved:
① Improve the machining accuracy of box support hole and main shaft journal;
② Improve the machining accuracy of the mating surface with the bearing;
③ Measure and adjust the radial runout range of the corresponding parts to compensate or offset the error.
2) Properly pre tighten the rolling bearing
① Clearance can be eliminated;
② Increase bearing stiffness;
③ Equalize the rolling element error.
03 Reduce transmission error of transmission chain
1) The number of transmission parts is small, the transmission chain is short, and the transmission precision is high;
2) Speed reduction transmission is an important principle to ensure transmission accuracy, and the closer the transmission pair is to the end, the smaller its transmission ratio should be;
3) The accuracy of the end piece shall be higher than that of other transmission parts.
04 Reduce tool wear
The tool must be grinded again before the tool size wear reaches the stage of sharp wear.
