Setting Spindle Speed of 2000 RPM

1.Make sure the spindle is completely stopped and the spindle lever is in the OFF (middle) position.

2.Move the spindle range lever to the right so that the arrow on top of its hub points toward the H (high) label (see the illustrated in Figure 68).

Note: If necessary, use the chuck key to rock the spindle back-and-forth to help mesh the gears as you move the levers.

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.

Spindle Speed Lever Set to

2000 RPM

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.

Figure 68. Setting the spindle speed to 2000 RPM.

3.Move the spindle speed lever so that the 2000 on its hub is also pointing at the H label.

Note: You will hear a distinctive click when the spindle speed lever is in the correct position.

The lathe is now set for a spindle speed of 2000 RPM.

The carriage can alternately 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 56.

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.
