CUTTING SPEEDS AND FEEDS
The table below shows RPM required to obtain a specified Tool Bit cutting speed on
the surface of a pipe or tube.
Use 200 surface inches per minute (5080 surface millimeters per minute) for
stainless steels in general when no coolant is allowed, all heavy wall tube, and some
chrome/molybdenum alloys.
Use 250 surface inches per minute (6350 surface millimeters per minute) for mild
steel and some thin wall stainless steel when coolant are permitted and used.
Use 300 surface inches per minute (7620 surface millimeters per minute) for
aluminum and thin-wall mild steel tube with coolant.
CUTTING FEEDS
Use very light feed for initial severing or until a continuous cut is established.
Use a feed rate .002” (.05 mm) to .003” (.08 mm) per revolution once a continuous
cut is established.
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 take on
a rough or torn appearance.
