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!

4.Remove the hex nuts and washers which hold the drive gears in place. Figure 9.
5.Remove the existing gears and replace with the new gears.
6.Replace the hex nuts and attach the drive gear cover.
