Setting Spindle Speed

1.Make sure the spindle is turned OFF and it has come to a complete stop.

2.Find the spindle speed range in the following options that is closest to your calculated spindle speed:

—20, 25, 35, and 50 RPM

—65, 85, 115, and 150 RPM

—210, 280, 380, and 500 RPM

—670, 900, 1200, and 1600 RPM

3.Move the spindle speed range lever (see Figure 66) so that the colors of the selected spindle speed range align with those of the stationary plate.

Figure 66. Spindle speed of 1600 RPM is selected.

4.Move the spindle speed lever to align the arrow on the inner hub with the same color as your selected speed on the outer hub.

Operating the lathe at spindle speeds higher than 350 RPM when the high (H) gearbox range is selected could result in gearbox damage. Always use spindle speeds of

350 RPM or lower when using the high (H) gearbox range.

Power Feed

Both the carriage and cross slide have power feed capability when the carriage is engaged with the feed rod. The rate that these components move (feed rate) is controlled by the headstock and quick-change gearbox lever positions, and the end gear configuration.

Feed rate and spindle speed must be considered together. Keep in mind that the feed rate is expressed in the amount of travel per revolution of the spindle. The sources you use to determine the optimum spindle speed for an operation will also provide the optimal feed rate to use with that spindle speed.

Often, the experienced machinist will use the feeds and speeds given in their reference charts or web calculators as a starting point, then make minor adjustments to the feed rate (and sometimes spindle speed) to achieve the best results.

The carriage can alternatively be driven by the leadscrew for threading operations. However, this section only covers the use of the power feed option for the carriage and cross slide components for non-threading operations. To learn how to power the carriage for threading operations, refer to Threading on Page 59.
