Grizzly G0492 owner manual Positioning Headstock, Using the Mill Table

Positioning the

Headstock

The mill headstock head can be raised and low- ered vertically, or rotated left or right up to 90º degrees to position the cutting tool next to the workpiece.

To position the spindle head vertically:

1.Make sure the spindle is stopped and the work area is free from obstructions before proceeding.

2.Loosen both column lock levers so that the headstock can freely slide on the column (Figure 41).

3.Rotate the mill height handwheel (Figure 41) to raise or lower the headstock to the desired position then lock the levers.

The headstock is heavy. Make sure that you support the headstock before you loosen the lock nuts. Ignoring this warning may allow the headstock to uncontrolla- bly swing over to the right or left causing injury or severe lathe/mill damage.

4.While supporting the headstock, use a 17mm wrench and loosen both left and right head- stock tilt lock nuts (Figure 42), then tilt the headstock to your desired angle. Retighten the lock nuts.

Using the Mill Table

The mill table of the Model G0492 can be moved in two axes—cross slide and longitudinal feed. Each of these axes are controlled by graduated handwheels to accurately position the workpiece in relation to the tool. To set the power feed for milling, refer to Setting Power Feed Rate on

Page 29.

Cross Slide

The cross slide is controlled by the cross slide handcrank of the lathe shown in Figure 43.

Longitudinal Feed Control

The longitudinal feed is controlled by the longitu- dinal handwheel of the lathe, and the lock at the back of the saddle (see Figure 43).
