1.先将机床找平，确定水平面。

　　First level the machine tool and determine the horizontal plane.

　　2.用测高仪测量导轨的高低差，找出距离较远的点，作为基准点。

　　2. Use an altimeter to measure the height difference of the guide rail and identify the point that is farther away as the reference point.

　　3.将滚动尺放在基准点上，测量丝杠与导轨之间的距离，并记录下来。

　　3. Place the rolling ruler on the reference point, measure the distance between the screw and the guide rail, and record it.

　　4.将滚动尺移到另一端，同样测量距离。

　　4. Move the rolling ruler to the other end and measure the distance as well.

　　5.比较两端的距离大小，如果相差较大，则需要进行调整。如果相差不大，则可以继续进行下一步。

　　5. Compare the distance between the two ends, and if there is a significant difference, adjustments need to be made. If the difference is not significant, you can proceed to the next step.

　　6.使用松动扳手，松开固定丝杠的螺钉，调整丝杠的角度，并再次测量距离。

　　6. Use a loosening wrench to loosen the screw that fixes the lead screw, adjust the angle of the lead screw, and measure the distance again.

　　7.根据测量值的变化，调整角度，直两端距离相等。

　　7. Adjust the angle according to the changes in the measured values until the distance between the two ends is equal.

　　8.再次使用测高仪测量导轨高低差，查看是否调整平行成功。

　　8. Use the height gauge again to measure the height difference of the guide rail and check if the parallel adjustment is successful.

　　9.若需要调整多个丝杠，则需要在调整一个丝杠之后，重新进行测量和调整，确保每个丝杠都与导轨平行。

　　If multiple screws need to be adjusted, it is necessary to re measure and adjust after adjusting one screw to ensure that each screw is parallel to the guide rail.
