For non-ferrous cutting head:
Same rules apply as with the ferrous cutting head. The selection of tooth configurations is more
limited with carbide.
Solid material from 2”- 4”: 14” x 60 tooth blade is recommended.
Solid material from 1”- 2”: 4” x 84 tooth blade is recommended.
Material less than 1”: 14” x 100 tooth blade is recommended.
Large extrusion with relief: 84-tooth blade may be used.
Any thin wall tubing or small extrusions with relief: 100-tooth blade.
•
There are different types of grinds for carbide, positive pitch and negative pitch. Positive
pitch blade for more aggressive cutting and negative pitch for thinner materials.
•
For some applications a high-speed steel blade is available for the non-ferrous cutting
head and normally run on the 1500 RPM setting.
•
Precision ground carbide blades may be purchased for a superior finish.
•
3000 RPM is the normal cutting speed for non-ferrous material with a carbide blade.
•
The non-ferrous blade will not normally throw a curled chip even if speeds and feds are
correct.
SPEEDS AND FEEDS
The best way to determine correct blade feed and speed is by the sound of the cut and chip
appearance.
Curly, shiny, cool chips: proper blade feed and speed.
Bent, discolored and/or hot chips: blade feed may be fast or slow.
Powdery or splintered chips: blade feed may be too fast or slow, incorrect blade may be in use.
