8.2 CUTTING FEEDS
Use very light feed for initial beveling or until a continuous cut is established. This
is very important for longer Tool Bit life when cutting through flame cut or out-of-
round pipe ends.
Use adequate feed, .003” to .006” (.08 mm to .15 mm) per revolution thereafter to
establish a continuous chip cut.
•
If the feed is too light, only light stringer chips will be removed.
•
If the feed is too heavy, the drive will start to overload and the chip will
start to have a rough edge or rough appearance.
•
Stainless steel, which work hardens, must be worked with a heavy enough
feed to stay under the work hardened surface [.003” to .006”(.08 mm to
.15 mm) feed].
Never allow the tool bit to burnish the surface.
Reduced feeds and speeds to minimize chatter problems.
