when rotated, then back off to give free rotation with no end play. Tighten the set screw in the boss.
RAM
Vertical play of the ram can be taken up by peeling off a leaf at a time from the laminated shims. Side play is adjusted with gib screws at the left side top edge of the column or body with the ram in the rearmost position. Adjust vertical play to 0.001" - 0.002", side play to 0.001" - 0.002". This allows a film of oil to "float" the ram.
The ram screw may be adjusted to remove excessive end play by tightening the nut on the extreme rear of the ram and securing with the lock nut.
TOOL POST CLAPPER
The tool post clapper hinges on a tapered pin which affords take-up adjustment.
If excessive play develops between the clapper and pin, tighten the nuts on the pin until play is eliminated. The clapper must fall freely into position by its own weight.
If pin is drawn up too tightly, loosen the nuts and lightly tap the pin with a hammer.
TABLE (VERTICAL MOVEMENT)
No play should be allowed in the column slides. The claping plates should be adjusted so that the cross slide willbe rigid when the eight hexagonal head bolts are tightened. A good way to do this is to make the adjustement so that the table will rise and fall without play when the eight bolts are tight. Then remove a further 0.002" lamination on each side for clamping. The gib at the left side should be adjusted for sliding with no play, but should not be locked.
TABLE (HORIZONTAL MOVEMENT)
Adjustements to the table cross slide are a little different from the ram and the column slides. The table should move freely on the cross slide, yet no play must be present. Excessive friction would result in broken feeding mechanism, and excessive play would cause chattering cuts and rough finish.
Adjustment of the table cross slides is made by removing (or inserting) shims which are placed between the bearing plates and held with eight |
socket head cap screws. These are accesable from the rear when the table is moved to the extreme right and extreme left.
Vertical play is taken up with three gib screws at the bottom of the table.
The cross slide screw may be adjusted to remove excessive play by tightening the nut on the left end of the cross slide screw and securing with the lock nut.
VICE
If vertical play develops in the sliding jaw, it can be eliminated by removing some laminations from the shims.
Remove the front support plate and two lock nuts an the end of the screw; pull the jaw assembly off the vice, remove the clamps and then re-assemble in the reverse order after having effected the necessary adjustments.
End play in the vice screw may be eliminated by tightening the nut on the screw at the end of the vice and securing with the lock nut.
TOOL POST SLIDE
The gib screws on the tool post slide should be kept tightened to prevent undue play. After tightening secure screws with lock nuts. When making this adjustment, be sure the gib is against the solid portion of the inner slide, otherwise a bent gib will result. The tool post slide feed screw may be adjusted for end play by the two nuts on the hub of the handle. To adjust, tighten the inner nut and lock with the outer nut.
CRANK BLOCK AND SLIDE
Machine tool builders, as a rule, do not attempt to provide adjustment on this particular part of a shaper. Any adjustment mechanism only complicates and introduces more delicate parts, giving trouble sooner than if left solid and allowed reasonable tolerance for wear. When worn to the stage of giving unsatisfactory service, these components must be renewed. Adequate lubrication of these parts will prolong their life.
END PLAY IN SHAFTS & SPINDLES
End play in shafts and spindles is taken up by means of collars with set screws in them. This |
