Setting Spindle Speed

Setting the spindle speed requires positioning the spindle speed range lever to either the high or low range, then using the spindle speed dial to set the speed, using the digital readout as a guide.

To set the spindle speed:

1.Press the STOP button and make sure the spindle is at a complete stop.

2.Rotate the spindle speed range lever (see Figure 64) to select the spindle speed range.

High Range (500–3000 RPM): Rotate the lever to the left.

Low Range (100–500 RPM): Rotate the lever to the right.

Note: If necessary, rock the spindle back and forth by hand to aid in meshing the headstock gears as you rotate the lever.

3.Rotate the spindle speed dial on the control panel all the way counterclockwise to set it at the minimum speed for startup.

4.Reset the STOP button and start spindle rotation.

5.Rotate the spindle speed dial slowly clockwise until the spindle has reached the desired speed, as displayed in the digital readout on top of the headstock.

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 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 54.

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.
