Tube Notching Machines

What a tube notching machine does

A tube notching machine punches an arc-shaped notch in the end of a round tube that matches the OD of another tube, so the two fit tightly for welding. The same class of machine is often combined with hole punching, flattening, angle cutting and oval forming, common in furniture frames, motorcycle racks, fitness equipment, hammer handles and garden tool handles.

Contract tube processing

TONG DA also processes tube on its own equipment: roll cutting, square cutting, notching, punching, flattening, shrinking, bending and end closing, for customers who prefer not to own the machine or whose volume does not yet justify it.

How to start

Send the part drawing, tube OD × wall × material and quantity; TONG DA advises whether buying or subcontracting works out better.
