6. Machine Accuracy Measurement and Adjustment
※ Note) L/M Guide Block realignment operation (X-Y plane)
(1) Refer to the “X-Y squareness” above to measure the exact squareness.
(2) Calculate the amount of the Liner polishing by calculating the length of
the square ruler and the distance between the Y-axis L/M Guide’s two
slide blocks.
▪ Since the distance between the two L/M Blocks is 600mm, multiply the
squareness measurement by 2.
(3) Slightly loosen the Y-axis L/M Guide’s Block fixing bolt.
(4) Loosen the Y-axis Ball Screw nut fixing bolt.
(5) From among ⓒ－ⓓ, if ⓒ is “+ ”, take out the left side Y-L/M Side Liner;
and if ⓓ is “+”, take out the right side Y-L/M Side Liner.
▪ After fully loosening the Y-L/M Block adherence Set-Screw (4-BQD8ⅹ
20), take out the Y-L/M Side Liner with the 4mm pin-removal tool.
(6) Polish the removed Liner as calculated in
“(2)” and reassemble it. Then,
strongly tighten the Set-Screw on the other side.
(7) Re-measure, and if acceptable, tighten the L/M Guide Block fixing bolts
(4-BB10×35).
(8) Transfer the Y axis to the
“-Y225 ” and then tighten the Y-axis Ball Screw
Nut fixing bolts.
