480 / 1" (diameter of workpiece) = 480 Result: the correct spindle speed is 480 rpM. Model g0554z (Mfg 01/09+) Examine the chart in Figure 52 or on the front of the headstock to determine the avail- able spindle speed closest to your calculated speed.
Feed power feed on the Model g0554z uses the machine to move the tooling rather than manual rotation of the handwheels. When the feed rod is engaged, the carriage or cross slide moves. threading operations use powered rotation of the longitudinal leadscrew with the half-nut engaged.

To engage the power feed for non-threading operations: Make sure the spindle is OFF and has come to a complete stop. Model g0554z (Mfg 01/09+) use the power feed direction lever to select the rotation direction of the feed rod (see the illustration in Figure 61).

Follow Federal, State, and the coolant manu- facturer's requirements to properly dispose of used coolant. Model g0554z (Mfg 01/09+) cleaning coolant Tank the coolant tank of your lathe holds approximately three gallons of coolant. replace the coolant every 30 days or sooner if it gives off a foul odor, which is due to the growth of dangerous microbes.
2. refer to rpM feed rate chart for appropriate rates. 3. sharpen or replace the cutting tool. 4. re-adjust the quick change gear setup with a small amount of backlash so the gears move freely and smoothly when the spindle is rotated by hand. Model g0554z (Mfg 01/09+)

1. Quill lock lever is tightened. not feed out of tailstock. Model g0554z (Mfg 01/09+) possible solution 1. Adjust for proper spindle speed and feed rate. 2. use sharp tools; use correct tool for the operation. 3. reduce depth of cut and take more passes.
-58- Gib Adjustments the Model g0554z has four gib adjustments: the cross slide gib, the compound gib, the saddle gib, and the tailstock gib. When adjusting gibs, the goal is to remove unnec- essary sloppiness from the movement of the slid- ing surfaces without causing them to bind.
Step 4 until you are satisfied with the results, then re-tighten the hex nuts without moving the set screws. Model g0554z (Mfg 01/09+) Tailstock Gib the tailstock gib is adjusted in the same man- ner as the cross and compound slide gibs (see Figure 89).
