Designed for superconductor and stainless steel applications – where tolerance and concentricity are critical, hydraulic drive outperforms chain‑type systems.
Two Machines, Two Different Requirements – One Common Choice
We have recently completed two sets of 10‑ton hydraulic cold drawing machines, each configured with a different effective drawing length to match specific customer needs. While the machines share the same hydraulic drive architecture, their applications could not be more different – yet both customers chose hydraulic over chain‑type for the same reason: superior tolerance and concentricity.
Case 1 – Superconductor Materials
Requirement | Detail |
Application | Drawing superconductor wires/tubes with extreme precision |
Why hydraulic? | Smooth, vibration‑free force prevents micro‑cracks and ensures uniform wall thickness |
Key benefit | Consistent reduction – essential for maintaining superconducting properties |
Case 2 – Stainless Steel Tubes (High Tolerance)
Requirement | Detail |
Application | Stainless steel tubes requiring tighter tolerances after drawing |
Why hydraulic? | Closed‑loop force control eliminates stick‑slip vibration – achieves ±0.015 mm accuracy |
Key benefit | Improved concentricity – reduces secondary machining and scrap |
Hydraulic vs. Chain‑Type – Why It Matters for Tolerance and Concentricity
Factor | Chain‑Type | Hydraulic (FangRong) |
Force application | Step‑wise, chain link pulsation | Smooth, continuous, infinitely variable |
Vibration amplitude | 0.15–0.30 mm – risk of chatter marks | <0.02 mm – no surface defects |
Speed stability | Fluctuates with chain tension | Constant – independent of load |
Concentricity | Moderate – risk of wall thickness variation | Excellent – uniform wall thickness |
Surface finish | Ra ≥0.6 µm | Ra ≤0.2 µm – mirror bright |
Overload protection | Shear pin breaks – production stop | Relief valve – machine continues |
Maintenance | Chain tensioning, sprocket wear | Hydraulic oil changes, seal kits |
Why Customers Choose Hydraulic for High‑Precision Applications
Better tolerance – closed‑loop force and position control maintains ±0.015 mm accuracy
Superior concentricity – smooth, vibration‑free force prevents wall thickness variation
More stable drawing process – constant speed independent of load
Improved surface finish – no chatter marks – ready for plating or anodizing
Energy efficiency – variable‑displacement pump reduces energy consumption by 15–25%
Key Technical Specifications – 10‑Ton Hydraulic Drawbench
Parameter | Range |
Drawing force | 10 tons (100 kN) |
Tube/bar diameter | 2 – 25 mm |
Wall thickness (tubes) | 0.2 – 4 mm |
Drawing length | Custom – configured per customer requirement |
Drawing speed | 0 – 20 m/min (programmable) |
Dimensional accuracy | ±0.015 mm |
Surface finish | Ra ≤0.2 µm |
If your metal material requires improved tolerance and concentricity, choose the hydraulic type to replace the chain type.
Hydraulic cold drawing machines deliver:
Tighter tolerances – ±0.015 mm or better
Better concentricity – uniform wall thickness
Smoother surface finish – Ra ≤0.2 µm
More stable operation – constant speed and force
Lower maintenance – no chain wear or tensioning
