Gibs

 

Return Spring

 

 

 

 

 

 

Gibs are wedge-shaped pieces of metal that fill the gap between the dovetailed ways of the machine. By adjusting the position of the gib in the gap, you can remove any play that might exist between the adjacent components. The gibs are pre-adjusted at the factory but due to storage, break-in, and usage, they may require adjustment.

To adjust the table gibs:

 

1.DISCONNECT MILL/DRILL FROM POWER!

2.Loosen the table travel locks.

3.Loosen or tighten the cross gib screws (Figure 58) in an alternating manner to adjust the cross travel gib.

The table should slide smoothly in the cross direction with no play or looseness. Do not overtighten the gibs or premature slide and gib wear will occur.

Gib Screw Location

 

Screw Location

 

 

 

The tail end of the spring is located on the perimeter of the spring housing. This part may be sharp! Use leather gloves or a heavy shop towel to cover the tail while loading or unloading return spring pres- sure. Failure to use such precautions may result in personal injury. Do not completely remove the cover! If you remove the spring cover, the spring will uncoil rapidly and create a risk of laceration or impact injury. Wear gloves and safety glasses during this procedure.

The spring tension for automatic quill recoil has been pre-set at the factory. It should not need adjustment under most normal circumstances. If it does need adjustment, the spring housing is located on the left side of the head.

To adjust the spring tension:

1.DISCONNECT MACHINE FROM POWER!

2.PUT ON SAFETY GLASSES!

3.Loosen the black thumb knob shown in Figure 59 two or three turns. DO NOT com- pletely remove the thumb knob.
