4 2 G10TE The Principles of Selecting Linear Guideway Identify the condition Applied equipment Inner space limit Accuracy Stiffness Way of loading Moving distance Moving speed, acceleration Using frequency Using life Environment Selection of accuracy Classes: C, H, P, SP, UP, Depends on the accuracy of equipment Assuming the size & the number of blocks Depends on experiences Load condition If accompanied with a ballscrew, the size should be similar to the diameter of ballscrew. For example, if the diameter of the ballscrew is 35mm, then the model size of linear guideway should be HG35 Calculate the max. load of block Make reference to load calculation examples, and calculate the max load Be sure that the static safety factor of selected guideway is bigger than that in the table of static safety factor Choosing preload Depends on the stiffness requirement and accuracy of mounting surface Identify stiffness Calculate the deformation (δ) by using the table of stiffness values, choosing heavier preload and bigger size linear guideway to enhance the stiffness Calculating service life Calculate the life time requirement by using the moving speed and frequency Selection of lubrication Grease supplied by grease nipple Completion of selection

12 10 G10TE The Butt-joint Rail

13 G10TE Layout Method Use of one rail and mounting reference side Use of two rails(block movement) Use of two rails(block fixed) Use of two external rails Use of two internal rails Total surface fixed installation HGW type block with mounting holes in different directions.

14 12 G10TE Installation of Linear Guideway Master and subsidiary guide Subsidiary HGH35C MA M aster Rigidity and high accuracy are required when the machine is subjected to vibrations and im p acts Table Rail push screw Subsidiary guide Bed Master guide Block push screw Rail Push Screw Fixing with a push plate Fixing with push screws Fixing with taper gib Fixing with needle roller

15 G10TE Oil stone Before starting, remove all dirt from the mounting surface of the machine. Tighten the push screws sequentially to ensure close contact between the rail and the side datum plane. Place the linear guideway gently on the bed. Bring the guideway into close contact with the datum plane of the bed. Tighten the mounting bolts with a torque wrench to the specified torque. Install the remaining linear guideway in the same way. Check for correct thread engagement when insert ing a bolt into the mounting hole while the rail is be ing placed on the mounting surface of the bed.

16 14 G10TE Installation example for the case when a rail on the master side has no push screws Table Block push screw Subsidiary guide Bed Rail Push Screw Master guide Using a vice Place the rail into the mounting plane of the bed. Tighten the mounting bolts temporarily; then use a vice to push the rail against the side datum plane of the bed. Tighten the mounting bolts in sequence to the specified torque. Subsidiary guide Method with use of a straight edge Master guide Method with use of a table Fix two blocks on the master guide side to the table. Temporarily fix the rail and one block on the subsidiary guide side to the bed and the table. Fixed a dial gauge stand on the table surface and bring it into contact with the side of the block on the subsidiary guide side. Move the table from one end of the rail to the other. While aligning the rail on the subsidiary side parallel to the rail on the master guide side, tighten the bolts in sequence. Method following the master guide side When a rail on the master guide side is correctly tightened, fix both blocks on the master guide side and one of the two blocks on the subsidiary guide side completely on the table. When moving the table from one end of the rail, tighten the mounting bolts on the subsidiary guide side completely. Master guide Subsidiary guide Master guide Subsidiary guide Method with use of a jig Use a special jig to ensure the rail position on the subsidiary guide side. Tighten the mounting bolts to the specified torque in sequence.

17 G10TE When there is no side surface of the bed on the master guide side Table Block push screw Subsidiary guide Bed Master guide Using a provisional datum plane Two blocks are fixed in close contact by the measuring plate. A datum plane provided on the bed is used for straight alignment of the rail from one end to the other. Move the blocks and tighten the mounting bolts to the specified torque in sequence. Method with use of a straight edge Use a dial gauge and a straight edge to confirm the straightness of the side datum plane of the rail from one end to the other. Make sure the mounting blots are tightened securely in sequence.
