G1128 Feed Rates
The optimum feed rate for the power feeder will
depend on the thickness of the material to be cut,
the hardness of the workpiece, the speed of the
cutting tool and number of teeth, tool shape etc.
Generally, the following rules can be followed
with a good level of success.
When selecting feed rates, remember these
important tips:
• The thicker the material to be cut, the slower
the feed rate.
• The harder the material, the slower the feed
rate.
• The faster the cutter speed, the faster the feed
rate.
• The greater the number of teeth or cutting sur-
faces, the slower the feed rate.
G1128 speeds: 12, 16.5, 20, 26 FPM
To change the speed of the G1128:
1. Remove the gearbox cover by unscrewing
the knobs on the front of the power head.
2. Determine the speed you desire, based on
your material and cutter configuration.
3. Locate the desired feed rate on the chart
shown in
Figure 8. The numbers on the
gears refer to the number of teeth on the
gear.
Do not try different arrangements!
