Tube expanding machine torque controller TDWTC

adjustable

Overview
A digital wattage-controlled torque system designed for controlled tube rolling and expansion. A single power source operates all compatible expansion drives. The controller automatically detects attached drives and provides repeatable tube expansion from 1/2" OD up to 3" OD. Precision is ensured with an accuracy of ±3% and stable performance despite supply voltage fluctuations.

Product Features

• Wattage-based torque control delivering consistent torque independent of supply voltage variations.
• Uniform, repeatable expansion across tube lengths and diameters.
• Automatic detection and integration of attached expansion drives.
• Single power source can feed multiple expansion drives for simplified setup.
• High accuracy (±3%) and operator-friendly interface to reduce process variability.

Technical description
The controller regulates drive power (wattage) rather than current, ensuring torque remains proportional to drive power at a constant RPM. By trip-setting at a fixed wattage, the system maintains consistent expansion results even when supply voltage varies — a common issue with current-based controllers. Engineered for heavy-duty, continuous operation, the TDWTC is suited to large-scale tube expansion projects and streamlines operator workflow while minimizing risks of over- or under-expansion.
