B-400 CNC Busbar Bending Machine
400 kN bending force · 15 × 200 mm processing range · ±0.3° with servo springback compensation
B-400 CNC Busbar Bending Machine
±0.3° bending accuracy with automatic springback compensation — so your busbars pass IEC 61439 temperature-rise inspection the first time.
Why the B-400 Holds Its Angle
Servo Springback Compensation
Every bend is measured in real time by an angle encoder. The servo system detects springback and over-bends precisely — the final angle lands within ±0.3°, batch after batch.
Flat · Edge · Twist Bending
Three bending modes with quick-change dies. Minimum inside radius R = thickness × 1.25 without surface scoring — critical for plating and insulation.
DXF Import & Auto Program
Import your CAD drawing; the control calculates bend sequence, springback values and part length automatically. Program a new job in under 2 minutes.

B-400 — Common Questions
How does ±0.3° accuracy stay stable over years of production?
The angle encoder recalibrates springback values continuously for each material batch, so die wear and material lot changes are compensated automatically — no manual re-teaching.
What is the delivery time?
Standard machines ship in 15–20 working days after payment; customized configurations 25–30 days.
Can it bend thick bars for transformers?
Yes — up to 15 mm thick × 200 mm wide in flat bending mode. For wider bars, ask about the JHMX-503 or production line options.
What training and after-sales support do you provide?
Remote installation guidance and operator training by video call are included. Spare parts ship from stock within 48 hours; technical response within 24 hours.
Does the price include dies?
The standard package includes a common die set for your stated bar size range. Additional or custom dies are quoted as options.
