Model 304 Tube Squaring Machine

NOTE:
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 or torn appearance.
Stainless, which work hardens, must be worked with a heavy enough feed to stay
under the work hardened surface.
Feed at a rate of at least .003” (.08 mm) to .006” (.15 mm) per revolution.
One revolution of the feed handle advances the cutiing head .100” (2.5
mm).
Never allow the tool bit to burnish the surface.
Reduce feeds and speeds will normally minimize any chatter problems.
A good rule of thumb for calculation purposes is a .0025” (.064 mm) thick chip per
revolution.
Actual measurements will show a pseudo thickness of .006” (.15 mm) unless a
pin micrometer is used for measuring.
