Grizzly G9298 owner manual Installation, Horizontal Position, Vertical Position

Installation

Before installing your rotary table, make sure that your mill table and spindle are properly aligned as instructed in your mill's owner manual. Also, remove any burrs or scratches from the mating surfaces of the mill and rotary tables by “stoning” them, then thoroughly wipe them clean and dry (refer to the Surface Care subsection on Page 18 for detailed instructions).

Horizontal Position

1.DISCONNECT MILL FROM POWER!

2.Position the rotary table horizontally on the mill table so that the center mounting slot is aligned with the center T-slot of the table.

3.Insert the M12-1.75 x 80 T-bolt into the mill table T-slot and slide it into the rotary table mounting slot, then install the flat washer and hex nut, but do not tighten them for now.

4.Use the horizontal clamp, M12-1.75 x 60 T-bolt, flat washer, and hex nut to hold the opposite end of the rotary table, but do not tighten it for now.

5.Place a precision square along the front edge of the mill table and the foot of the rotary table, square the rotary table to the mill table, then fully tighten the hex nuts.

6.Perform the Alignment procedure as instruct- ed on Page 9.

You MUST properly secure the rotary table to the mill table to prevent unexpected movement during operation, which could result in personal injury or damage to the workpiece.

Vertical Position

It will be necessary to compare the center-to-cen- ter distance between the T-slots of your mill table to the vertical mounting holes of the rotary table. If the mounting holes do not intersect the mill table T-slots with sufficient space for the T-bolts, use step blocks and clamps in place of one of the T-bolts.

The alignment keys on the foot of the rotary table measure approximately 0.630" (16mm) and are used to align the rotary table. If they are wider than the mill table T-slots, machine a step into them so that they will fit properly. Otherwise, they can be removed to allow manual alignment.

To install the rotary table in the vertical posi- tion:

1.DISCONNECT MILL FROM POWER!

2.Insert the two M12-1.75 x 60 T-bolts in the outer slots of the mill table.

3.Align the vertical mounting holes of the rotary table with the T-bolts, then place the rotary table onto the mill table with the alignment keys, if used, into the table's center slot.

—If the alignment keys are not used, place a precision square along the mill table front edge and the machined side of the rotary table foot, then square the rotary table to the mill table.

4.Install the flat washers and hex nuts onto the T-bolts to secure the rotary table in place.

5.Perform the Alignment procedure as instruct- ed on Page 9.

NOTICE

Make sure the rotary table handwheel is free of obstructions. Depending on your setup, the rotary table may need to be blocked up or mounted so the handle is hanging over the edge of the mill table. After installation, carefully check for any possible obstruc- tions that may interfere with the rotary table or its handwheel.
