Understanding Thread & Feed Rate Chart

A complete threading and feed rate chart is located on the face of the headstock that shows all available threading and feed configurations for your lathe. Chart use is described below.

Positioning Gearbox Levers

To cut a thread or establish a particular feed rate, you may need to first reposition the transposing gears located behind the end gear cover.

Once you have confirmed that the change gears are positioned according to what the thread and feed rate charts require, you then can move the quick change gearbox levers to the required positions, which are indicated by an alpha- numeric code on the thread and feed rate chart. For this example, an inch thread of 7 TPI is desired. The alpha-numeric code displayed on the chart shown in Figure 103 is HBS8W.
