SB38NC ROUND TUBE BENDER TUBE BENDING MACHINE
Semi-automatic NC pipe bending machines are designed as
alternatives to CNC pipe bending machines with a lower cost than
CNC models. It will help you to reach your target in the most
economical way on pipe and tube bending works.
It uses a single-chip NC unit to control the running. The feeding
and rotation are positioned by manual, the bending is controlled by
a hydraulic cylinder. Suitable to bend simple bend parts or simple
multi-plane parts with medium volume.
We can use it for bending various materials such as stainless
steel, aluminum, copper, carbon steel, etc.

Tools:
Optional tools: wiper die, mandrel to effectively control the deformation and wrinkling of the
processed pipe during bending. Bending without a mandrel is
relatively simple. Generally, a tube with a small diameter, such as
a 6-8 mm tube, which has more support on its own, it is not
necessary to use a mandrel, and the ellipticity is within 5% of the
tube’s outer diameter. Some galvanized pipes and iron pipes with
large bending radius and thick walls can also be made without
mandrels. However, for thin-walled pipes with small bending radius and large
diameter, a mandrel should be used to support the inner wall of the
pipe to prevent its cross-section from turning oval and wrinkling
at the inner side.
Tools material: mainly selected according to the pipe material and the bending
difficulty. Common materials are 45#, Cr12, industrial nylon,
42MrMo, copper. Generally, we use 42MrMo,it’s vacuum quenched, the
surface is nitrided, and the hardness of the mold surface is not
less than HRC55 to ensure the wear resistance of the mold.
Tools size: customized according to the bending radius of different pipes.
