Installing Tooling

This tailstock uses a quill with an MT#5 taper that has a lock slot in the back of the bore that accepts tang arbors and drill bits (see Figures 41–42for examples).

However, other tooling without tangs, such as the four remaining tools shown in Figure 41, can still be used if the potential load will not exceed the strength of the tapered fit. For example, this includes smaller drill chucks, drill bits, and centers.

retracted for tool removal. Otherwise, removal of such tooling may be difficult.

To install tooling in the tailstock:

Tang

1.With the tailstock locked in place, unlock the quill, then use the handwheel to extend it approximately 1".

2.Thoroughly clean and dry the tapered mating surfaces of the quill and the center, making sure that no lint or oil remains on the tapers.

Note: If the tapered tool shaft has a tang, align it with the slot in the back of the quill before seating it.

3.With a firm and quick motion, insert the tool into the quill. Check to see if it is firmly seated by attempting to twist it—a firmly seated tool will not twist.

4.Unlock the tailstock and move it until the tip of the tool is close to, but not touching, the workpiece, then re-lock the tailstock.

5.Start spindle rotation, unlock the quill, then turn the tailstock handwheel clockwise to feed the tool into the workpiece.
