Using The Thread Chart - Grizzly G0600 Manual Insert

Using the Thread
Chart
This lathe comes with one 48-tooth and two 57-
tooth change gears installed for cutting inch or
metric threads. For cutting dimetrial or modular
pitch threads, certain gears must be replaced
and repositioned (refer to Dimetrial and Modular
Pitch Threading on Page 41).
Example: To cut a modular pitch thread of 0.5, the
threading chart in Figure 56 indicates that you
must change the gears into the (W) mode shown,
and move the levers and dials to positions I, C, F,
S, and 4 (Figures 54 and 55).
To cut inch and metric threads, or to use the chart
for the X and Y power feed rates, the change
gears must be changed to the (V) mode. Refer to
Inch and Metric Pitch Threading on Page 43.
