Tips For a Good Finish
Single Point Flange Facing/Beveling Module
1. Always place mandrel as close to pipe end as possible.
2. Use cutting coolant generously. This will also increase cutter life.
3. CHATTER: Tool chatter occurs when the tool begins to vibrate during cut. Excessive tool
chatter can cause poor quality surface finishes. Chatter can be caused by any one of a number
of variables inherent in a portable machine of this type.
4. INTERMITTENT CUTS: When working on a rough cut end of a piece of pipe or a warped
flange, tou will need to do an intermittened cut. In order to prolong tool life and reduce shock
loads on the machine and inserts, intermittent cuts should be performed at a slower feed rate.
Once a full cut is achieved, operating speeds can be increased to normal.
5. As you finish a pass, note your location on the indiced axial feed gauge. Take your next pass;
rotate the feed handle backwards one full turn to your noted location and retract your tool slide.
Once retracted, rotate the feed handle in the amount you wish for the cut depth of your next
pass. This will allow you to retract the slide without damaging the tooling, remove all backlash
in the feed handle and give you an exact depth of cut on your next pass.
