Model 308, Tube Squaring Machine

NOTE:
Stainless, which work hardens, must be worked with a heavy enough feed to keep
the edge of the tool bit under the work hardened surface [.003” to .006”(.08 mm to
.15 mm) feed.] Never allow the tool bit to burnish the surface.
Reduce feeds and speeds will normally minimize chatter problems.
A good rule of thumb for calculation purposes is to produce a .0025” (.64 mm) thick
chip per revolution. Actual measurements will show a pseudo thickness of .006”
(.15 mm) unless a pin micrometer is used for measure.
One revolution of the feed knob will advance the cutting head .044”
(1.12 mm).
