(Fig.18)a. Check if any of the bolts has a sinking.b. Use a torque wrench to tighten the boltsin order from the center to both ends.(3) Mount the LM blocks on the table, theninstall them onto the LM rails. Be sure themounting bolts for the LM blocks are temporarilyfastened.(4) Tighten the clearance adjustment bolt alternatelyto adjust the clearance.If a relatively large preload is applied inorder to achieve high rigidity, control thetightening torque or the rolling resistance.a. It is preferable to use three clearanceadjustment bolts for each LM block asshown in Fig.19.b. To obtain a favorable result of the clearanceadjustment, set the tighteningtorque of the two outside screws atapprox. 90% of that of the enter screw.(5) Secure each LM block by gradually tighteningthe two LM block mounting bolts, whichhave temporarily been fastened, while slidingthe table.
