Additionally, due to the circular-arcgroove design, it is capable of carrying a preload as necessary to increase its rigidity.When compared with a feed screw shaft system and a spindle in rigidity, the guide surface using an<strong>LM</strong> <strong>Guide</strong> has higher rigidity.• Example of comparing static rigidity between the <strong>LM</strong> <strong>Guide</strong>, a feed screw shaftsystem and a spindle(vertical machining center with the main shaft motor of 7.5 kW)[Components]<strong>LM</strong> <strong>Guide</strong>: SNR45LC/C0(C0 clearance: preload = 8.05kN)Ball Screw: BNFN4010-5/G0(G0 clearance: preload = 2.64kN)Spindle: general-purpose cutting spindle<strong>LM</strong> <strong>Guide</strong>Ball ScrewXComponentsTable2 Comparison of Static RigidityUnit: N/μmX-axisdirectionY-axisdirectionZ-axis direction<strong>LM</strong> <strong>Guide</strong> — 21108700 (radial)6730 (reverse radial)Ball screw 330 — —Spindle 250 250 280Note) The rigidity of the feed screw shaft system includesrigidity of the shaft end support bearing.ZYSpindle<strong>Industrial</strong> <strong>Technologies</strong>Fig.3A1-6
