Overview
The 75CNC pipe bending machine is a CNC pipe bender for tube up to Φ76.2 × 3 mm, three inches, on a 3800 mm mandrel, with a 300 mm maximum bend radius and a 3.2 tonne frame.
Bend speed drops to 35°/s here against 100°/s on the smallest model. That is deliberate. Larger sections need controlled metal flow, and pushing them faster costs springback consistency. This is the common size for commercial vehicle and machinery exhaust, where a mandrel bender and matched wiper dies are what keep thin-wall stainless from wrinkling on the inside radius.
