Product Description

Features of CNC automatic pipe bending machine SB-50CNC-4A-2S:


1. Customized production: We can manufacture CNC automatic pipe bending machine SB-50CNC-4A-2S according to your requirements.

2. The complete set of tooling includes: pipe bending die, clamping die, pressing die, chuck (CNC), mandrel (optional), wiper die (optional).

3. Safety board: If a person standard touches the bending arm, the CNC automatic pipe bending machine SB-50CNC-4A-2S will automatically stop to ensure the safety of the workers.

4. Touch screen: machine operation through touch screen. You can input all bending data into the touch screen, PLC receives the touch screen program, CNC automatic pipe bending machine SB-50CNC-4A-2S will work accordingly according to each requirement.

5. Feeding servo motor: The electric feeding tube feeds back and forth. The pipe feeding can only be controlled by the servo motor to ensure the pipe feeding accuracy and ultimately the bending accuracy.

6. Feeding trolley (collet): The feeding trolley has the functions of front and rear feeding pipes, rotating pipe fittings at different angles and clamping pipe fittings. It is a very important equipment in CNC automatic pipe bending machine SB-50CNC-4A-2S.
