Depending on the combined configuration of

the headstock feed direction lever and the

apron feed direction knob, the actual direction

of power feed may be different from the

printed indicators on the machine!

E. Feed Selection Lever: Directs the power feed

to either the cross slide or the carriage.

When the lever is down and the indent pin

is pointing up, the cross slide is selected.

Conversely, when the lever is up and the pin

is pointing down, the carriage is selected.

In the middle position, the apron gears are

disengaged from the feed rod and neither

component will move.

Note: When using this lever, you may need

to slightly rotate the handwheel of the

component you are trying to engage, so that

the apron gears can mesh.

F. Apron Feed Direction Knob: Changes the

feed direction when the lathe is running.

The advantage of this knob is that you can

quickly reverse power feed direction while

the spindle is rotating—without having to

turn the lathe off, waiting until the spindle is

stopped, then using the feed direction lever

on the headstock.

When using power feed to move the cross

slide, the feed rate is

the value stated in

the feed rate chart.

Setting Power Feed Rate

The feed rate chart on the upper right of the

headstock face displays the settings for the

headstock feed controls for metric and inch feed

rates.

Using the controls on the lathe, follow along with

the example below to better understand how to

set the lathe for the desired power feed rate.

Setting Power Feed Rate of 0.18mm/rev

1. Make sure the end gears are in the standard

configuration, which is applicable for general

feed operations (refer to End Gears on the

next page for detailed instructions).

2. Locate the line in the feed rate chart that

lists the setting for 0.18mm of feed per

revolution of the spindle, as illustrated in

Figure 72.
