Grizzly g0746, g0749 Micrometer Stop, Manual Feed, Carriage Handwheel, Cross Slide Handwheel

Micrometer Stop

Use the micrometer stop as a guide to help judge when to stop carriage movement.

The micrometer stop on this lathe will NOT automatically stop the carriage during threading operations when the carriage is engaged with the leadscrew! Failure to heed this notice could result in the carriage crashing and causing severe machine or property damage.

To set the micrometer stop:

1.disCONNECT LATHE FROM POWER!

2.Use the carriage handwheel to position the carriage and cutting tool at the desired stop- ping point, then loosen the front cap screws on the micrometer stop (see Figure 68).

Carriage Handwheel

The carriage handwheel moves the carriage left or right along the bed. It has a graduated dial with 0.005" increments. One full revolution moves the carriage 0.55".

Cross Slide Handwheel

The cross slide handwheel moves the tool toward and away from the work. Adjust the position of the graduated scale by loosening the thumb knob, holding the handwheel with one hand and turning the dial with the other, then tightening the thumb knob. The cross slide handwheel has a direct-read graduated dial, which shows the total amount of material removed from the diameter of the workpiece. The dial has 0.004" (0.01mm) increments, and one full revolution moves the slide 0.200". Rotate the dial collar 180° to read in metric units.

Compound Rest Handwheel

The compound rest handwheel moves the cutting tool linearly along the set angle of the compound rest. Adjust the position of the graduated scale in a similar manner with the handwheel and dial. The compound rest angle is set by hand-rotating it and securing in place with four hex nuts. The compound rest has an indirect-read graduated dial with 0.002" (0.05mm) increments. One full revolution of the handwheel moves the slide 0.200".
