CBC UNI Mandrel Tube Bender
The CBC range of mandrel tube bending machines have been designed to meet the requirement to bend thin wall tube to tight radii. The mandrel is positioned at the point of bend to prevent wrinkling on the inside and flattening on the outside. A slider guide moves in tandem with the tube to prevent marking, particularly to decorative material such as stainless steel.
The UNI 63 model has manual mandrel extraction and manual clamping of the tube during the bend, and is designed to bend tube to a minimum radius of 2 times the tube diameter. Other models are available in the range to accommodate larger tube diameters and even tighter bending radii.

CBC UNI Mandrel Tube Benders – Precision, Power & Durability
The CBC UNI mandrel tube bending machines are expertly engineered to bend thin-wall and larger-diameter tubes into tight radii with exceptional quality. Featuring a mandrel placed at the bend point to eliminate wrinkling and maintain consistent wall thickness, plus a slider guide that moves with the tube to prevent surface marking, they deliver pristine results—especially on finishes like stainless steel.
Key Benefits
-
Wrinkle-free bends: Internal mandrel supports prevent inward collapse of the tube, while external formers guard against flattening.
-
Surface protection: The guided slider die ensures scratch-free bending—vital for decorative, polished finishes.
-
Programmability: Digital models store up to 50 programmes with 9 bends each.
-
Space efficient: Compact footprints allow these machines to fit into most production environments without sacrificing capacity.
