Home / Blog / ACE Suzhou Deploys AMADA + YASKAWA Dual-Robot Bending Cell for Front-End Fabrication
August 4, 2026
1. What We Deployed
ACE's Suzhou facility recently completed a bending cell upgrade in the front-end sheet metal shop. The new setup pairs an AMADA HRB-series CNC press brake with two YASKAWA six-axis robots — each robot equipped with dedicated end-of-arm tooling, working in a sequential-split collaboration mode.

2. How It Works: Bending Sequence Split Across Two Robots
Standard press brake automation is "one brake + one robot for load/unload" — the robot is essentially a moving arm doing the operator's material handling job.
This cell uses a sequential-split collaboration approach: the bending sequence for a single part is divided across two robots that hand off the semi-finished part between them.
Operational sequence:
- Robot A picks a laser-cut blank from the input rack, feeds the brake, brake executes the first bend group (e.g., three primary reference bends)
- Robot A transfers the semi-finished part to the intermediate handoff table
- Robot B picks from the handoff table, feeds the brake, brake executes the second bend group (additional bend sequences)
- Robot B places the finished part on the output rack
- The on-floor operator handles inspection and packing at the output rack
Both robots work in coordination — while one is feeding the brake, the other places the previous part on the handoff table. Cycle rhythms interlock, reducing equipment idle time.
3. Why AMADA + YASKAWA
Brand choice is driven by the order profile, not signaling.
Press brake: AMADA (Japan) - AI server rack and semiconductor equipment structural parts require tight within-batch tolerance - AMADA HRB series delivers the repeatability and hydraulic response curve needed for stable continuous production - Long-term MTBF is high — downtime cost matters when running production batches
Robot: YASKAWA (Japan) - 6-axis articulated robots with stable repeatability - Communication protocol matures cleanly with AMADA brakes — handoff latency is minimal - Long-validated reliability across semiconductor and automotive industries
Why dual robots, not single - A single robot doing all bend sequences leaves idle time while the brake is forming - Dual robots in split-sequence mode keep both robots more consistently engaged - The press brake stops being the line bottleneck; single-shift effective output is more predictable
4. What This Means for OEM Customers
1. Tighter lead-time commitments — Batch bending cycle time is more predictable. Scheduling windows narrow, customer date commitments become more defensible.
2. Batch-to-batch consistency — The bend reference on every part is locked by robot gripper positioning. Variance vs. manual load is reduced — direct improvement to first-pass yield in downstream welding and assembly.
3. Flexibility preserved — The program library supports fast changeover across multiple products. Automation doesn't lock us into large-lot-only economics; small and mid-batch orders remain viable.
5. Where This Cell Sits in ACE Suzhou's Automation Map
Bending is one link in the broader precision fabrication chain. Suzhou facility automation posture:
| Process | Automation level |
|---|---|
| Laser cutting | 10 kW+ fiber laser · automated loading/unloading |
| Press brake bending | AMADA + dual YASKAWA robots · sequential-split collaboration (this upgrade) |
| Welding | TIG / MIG / robotic welding cells · AWS D1.1 / D1.2 / D1.3 / D1.6 · PQR-qualified WPS |
| Surface finishing | Powder coating line · cross-cut adhesion test qualified |
| Cleanroom assembly | ISO Class 7 (10,000-particle) cleanroom · ISO Class 8 general assembly |
| Outgoing inspection | FAI / PPAP · CMM dimensional |
| Other automation | 2 automated grinding machines · gantry machining center · automated copper/aluminum bar loading · automated bench-fitting station |
From laser cutting through cleanroom assembly, process transitions are largely automated.
