Installation Procedure Setting the curved tracking bases temporarily

(1) Remove burrs, stains, and dust from the installation surface of the curved tracking bases of tables and beds. Foreign objects must be kept out of the assembly work as well.(2) Apply oil of low viscosity to contact surfaces, check the reference edges of an A-curved tracking base and bed, and then tighten the bolts temporarily. (Figure H-39)(3) Align the reference edges (NB mark side) of a B-curved tracking base and an A-curved tracking base to the same orientation. Then, insert the curved roller cage between the curved tracking bases at the center area. Make sure that the curved roller cage will not interfere with the curved raceway grooves of the curved roller tracking bases. (Figure H-39b)(4) Check the reference edge of the table, set the table over the B-curved tracking base, and then secure the table temporarily. (Figure H-39c)

Setting four curved tracking bases in parallel position

(5) Move the table to the maximum stroke ends of both sides and adjust the setting so that the curved roller cage is positioned at the center of the curved tracking base.(6) Move the table to the center position and tighten the adjustment screw with slightly strong torque * by using a torque wrench. (Figure H-39d)

* "Slightly strong torque" here means slightly stronger than the torque at which the oscillation of the test indicator is stabilized at the minimum value when the table is moved right and left, or when pressure is applied to the rolling direction while the test indicator is attached to the side face (reference side) of the table. (Figure H-40i)

(7) Move the table to the maximum stroke end of one side and tighten the regulating screw on the curved roller cage with the same torque as in step (6). (Figure H-39e)

Adjustment screw can be tightened Adjustment screw should not be tightened
