EMAC-BB-S12
Servo 3D busbar bending machine, 400 kN, ±0.1°, no hydraulics
- Nominal force
- 400kN
- Bending accuracy
- ±0.1°
- Bending capacity (W × T)
- 200 × 16mm
Overview
EMAC-BB-S12 is the pure servo configuration of the 400 kN bending platform, holding the same ±0.1° bending accuracy on bar up to 200 × 16 mm. Maximum bending stroke is 250 mm, side gauge stroke 1200 mm at 80 m/min, and maximum bending angle 90°. With no hydraulic station there is no oil to manage, idle power draw is lower and noise is reduced, which suits a clean assembly area and an intermittent duty cycle. Electronic springback compensation and one-touch die calibration are standard. Installed power is 6.25 kW.

Frequently asked questions
- Hybrid hydraulic or pure servo?
- Pure servo draws less energy at idle, runs quieter and has no oil to manage, which suits a clean shop and an intermittent duty cycle. The hybrid station holds force better at full stroke on heavy sections and costs less. Both hold ±0.1°. Work that sits near the top of the capacity envelope most days is better served by the hybrid.
