1.先將機床找平，確定水平面。

　　First level the machine tool and determine the horizontal plane.

　　2.用測高儀測量導軌的高低差，找出距離較遠的點，作為基準點。

　　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.將滾動尺放在基準點上，測量絲杠與導軌之間的距離，并記錄下來。

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

　　4.將滾動尺移到另一端，同樣測量距離。

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

　　5.比較兩端的距離大小，如果相差較大，則需要進行調整。如果相差不大，則可以繼續(xù)進行下一步。

　　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.使用松動扳手，松開固定絲杠的螺釘，調整絲杠的角度，并再次測量距離。

　　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.根據測量值的變化，調整角度，直兩端距離相等。

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

　　8.再次使用測高儀測量導軌高低差，查看是否調整平行成功。

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

　　9.若需要調整多個絲杠，則需要在調整一個絲杠之后，重新進行測量和調整，確保每個絲杠都與導軌平行。

　　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.
