Powered by Inovance servo motor technology, FangRong’s hydraulic drawbenches deliver ±0.02mm accuracy, smooth operation, and seamless PLC integration – the optimal choice for demanding tube and bar drawing applications.
The Drive System Decision – Why It Matters
For hydraulic cold drawing machines, the choice of drive motor is not a trivial detail – it directly affects precision, stability, and control flexibility. Manufacturers can select either a standard AC motor or a high-performance servo motor, depending on their specific production requirements.
While AC motors are suitable for general-purpose drawing, servo motor drives offer distinct advantages for applications requiring tight tolerances and consistent quality.
Why Choose a Servo Motor for Your Hydraulic Drawbench?
Advantage | How It Translates to Your Production |
Superior PLC integration | Seamless communication between the drive and control system – easier programming, faster setup, and real‑time parameter adjustment |
More stable machine operation | Consistent drawing speed and force throughout the entire cycle – eliminates fluctuations that cause dimensional variation |
High precision and tight tolerance capability | Achieves ±0.02mm repeatability – essential for medical, aerospace, and automotive components |
Energy efficiency | Servo systems deliver power on demand, reducing energy consumption by 30–70% compared to conventional motor drives |

Servo-Hydraulic Cold Drawing – How It Works
The integration of a servo motor with a hydraulic system creates a servo-hydraulic drawbench – combining the smooth, high-force capability of hydraulics with the precision and responsiveness of electronic control.
Component | Function |
Servo motor | Provides precise, programmable speed and torque control |
Variable‑displacement pump | Delivers hydraulic power on demand – reduces energy waste |
Closed‑loop PLC control | Monitors and adjusts drawing force, speed, and position in real time |
High‑precision guide rails | Maintain alignment and repeatability during the drawing cycle |
The result: A drawing machine that can achieve ±0.02mm dimensional accuracy with stable, repeatable performance – shift after shift.
Applications Where Servo-Driven Hydraulic Drawing Excels
Medical – Hypotubes, guidewire blanks, surgical instrument tubes – where ±0.015mm tolerance is non‑negotiable
Aerospace – High‑strength thin‑wall tubing for hydraulic and fuel systems – requiring consistent mechanical properties
Automotive – Fuel injection lines, battery cooling tubes, steering components – high‑volume production with tight tolerances
Precision instrumentation – Capillary tubes, sensor housings – where surface finish and dimensional stability are critical
AC Motor vs. Servo Motor – A Practical Comparison
Factor | AC Motor Drive | Servo Motor Drive |
Precision | Moderate (±0.05–0.10mm) | High (±0.02mm or better) |
Speed control | Limited | Infinitely variable – programmable |
PLC integration | Basic | Seamless – easy to program and monitor |
Energy efficiency | Moderate | High – 30–70% energy saving |
Stability | Moderate – fluctuations possible | Stable – consistent under varying loads |
Best for | General‑purpose drawing | High‑precision, tight‑tolerance applications |
