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.
