Notching Tips

See below for some helpful tips to keep your
machine performing its best and to obtain the best
notching results.
• Only notch one workpiece at a time.
• Smooth material will notch more easily than
rough or dirty material. Clean/deburr material
before inserting into the machine.
• If the notching dies do not return to the open
position after operation, there may be a cut
off piece stuck in the way. Disconnect the
machine from power before removing the
guards and cut off piece.
• Find and mark a straight "center" line paral-
lel to the workpiece edges (see Figure 9) on
either side of the workpiece to achieve even
notches. Align this line to the top of the notch-
ing hole for each operation so the second
notch will align with the first.

• Lubricate the notching dies every 10–12 cuts
during continuous use.
• Empty the chip drawer periodically to keep
cut off pieces from accumulating and lodging
in notching mechanisms.

Cutting Notches

Cutting a notch in a tube or pipe consists of pre-
paring the workpiece, lubricating the notching
dies, determining the size of notching hole need-
ed for the operation, and making two identical
cuts, one on either side of the workpiece. Once
a pipe or tube has been notched, the notched
edges can be tightly welded or otherwise joined
to another workpiece.

ready to be joined.
