NC Semi-Automatic Tube Bender

75NC NC Semi-Automatic Tube Bender

NC semi-automatic tube bender for tube up to Φ76.2 × 3 mm, running 32°/s on a 3400 mm mandrel. The wall thickness step up to 3 mm makes it the entry point for structural tube rather than furniture tube. Hydraulic bending, hand feed and rotation, repeatable to ±0.1°.

Overview

Product Details

Overview

The 75NC tube bender is an NC hydraulic machine for Φ76.2 × 3 mm mild steel or Φ51 × 2 mm stainless, on a 7.5 kW drive with a 3400 mm mandrel and a 280 mm maximum bend radius.

Three inch tube in mild or stainless steel is exhaust and silencer territory, and thin-wall stainless exhaust in particular wants a mandrel and a wiper die to stop the inside radius wrinkling. The motor step from 5.5 kW to 7.5 kW at this model is not proportional to diameter — bending force rises roughly with the cube of it.

FAQ

75NC NC Semi-Automatic Tube Bender — Common Questions

Φ76.2 × 3.0 mm in carbon steel — three inches — and Φ51 × 2.0 mm in stainless, on a 7.5 kW hydraulic drive. Maximum bend radius is 280 mm and maximum mandrel length is 3400 mm.

Bending force rises roughly with the cube of diameter, not linearly, so each step up the range needs a disproportionate increase in drive. That is also why machine weight goes from 1000 kg on the 63NC to 2000 kg here: the frame has to react the force, not just house the cylinder.

Yes. Exhaust work is usually Φ50–Φ76 mm in mild or stainless steel with thin to medium wall, which sits in this machine's range. Thin-wall stainless exhaust in particular wants a mandrel and a wiper die to stop wrinkling on the inside radius.

The machine will either stall or bend more slowly and less accurately, and the tooling takes the punishment. The rating is a working figure that assumes reasonable radius and material; a heavier wall at a tight radius can exceed it even when the diameter is well inside range.

Yes. Bend die, clamp die, pressure die, wiper die and mandrel are matched to your tube diameter, wall and centre-line radius. Tooling is quoted against your drawing, since a machine without the right die set cannot make your part.
