(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 <strong>LM</strong> blocks on the table, theninstall them onto the <strong>LM</strong> rails. Be sure themounting bolts for the <strong>LM</strong> 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 <strong>LM</strong> 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 <strong>LM</strong> block by gradually tighteningthe two <strong>LM</strong> block mounting bolts, whichhave temporarily been fastened, while slidingthe table.
