2PF300/500/1000 Professional Welding Positioner

OTC DAIHEN A2PF Series High‑Precision Dual‑Axis Servo Positioners

The A2PF series from OTC DAIHEN are high‑performance dual‑axis servo positioners designed for robotic automation welding. The series covers six models from 25kg to 1000kg payload; here we feature the A2PF300-ENN (300kg), A2PF500-ENN (500kg), and A2PF1000-ENN (1000kg). Equipped with AC servo motors and backlash‑free reducers, they achieve an impressive ±0.08mm repeatability at R250, matching the precision of the robots themselves. They can be operated directly via the robot teach pendant and taught simultaneously with the robot, greatly simplifying programming. Optional coordination software enables perfect dual‑axis synchronized motion for complex workpieces. With rotation speeds up to 180°/s, they significantly boost production cycle times.

✨ Key Technology Advantages

• High‑precision drive — AC servo motor + backlash‑free reducer, ±0.08mm repeatability (at R250).

• Dual‑axis coordination — Rotation + tilt axes for complex workpiece positioning.

• Integrated robot operation — Controlled directly from the robot teach pendant.

• High speed — Rotation up to 180°/s, dramatically improving cycle time.

• High torque capacity — Allowable torque up to 882 N·m; tilt axis allowable twist up to 3704 N·m.

• Arbitrary stop position — Both axes stop at any desired angle.

🔧 Primary Applications

Automotive manufacturing, construction machinery, motorcycle frames, steel structures, pipe prefabrication – robotic welding lines requiring dual‑axis coordinated motion for complex parts.
