17‑Meter Drawing Length Cold Drawing Machine – Engineered for Extra‑Long Precision Tubes and Bars
- 5 days ago
- 3 min read
Extended‑length hydraulic and servo‑electric drawbenches now available for producing extra‑long precision components – ideal for aerospace hydraulic lines, oil & gas instrument tubing, linear shafts, and structural sections up to 17 meters.
Why 17‑Meter Drawing Length Matters
Standard cold drawing machines typically accommodate lengths of 6 to 12 meters. For manufacturers requiring extra‑long tubes and bars, a 17‑meter drawing length opens new possibilities:
Fewer end welds – One piece replaces multiple shorter sections in fluid and gas systems
Lower scrap rates – Reduced remnant losses from cutting long stock into final lengths
Higher value products – Extra‑long precision components command premium pricing
Direct supply to OEMs – Meet customer specifications for one‑piece hydraulic lines, structural rails, and guide rods
Key Technical Specifications
Parameter | Value |
Maximum drawing length | 17,000 mm (17 m / 55.8 ft) |
Drawing force | 15 – 300 tons (customizable) |
Tube OD range | 6 – 150 mm |
Bar diameter range | 5 – 120 mm |
Wall thickness | 0.5 – 20 mm |
Drawing speed | 0 – 15 m/min (programmable) |
Dimensional accuracy | ±0.02 mm to ±0.05 mm (depending on material) |
Extended Machine Features for 17‑Meter Capacity
Designing a drawbench for 17‑meter drawing length requires significant engineering upgrades:
Extended, rigid carriage guide – Ultra‑long, precision‑ground rails prevent deflection over the full stroke
Heavy‑duty chain or hydraulic cylinder – Sized for smooth, consistent force across the extended draw
Multiple die boxes (optional) – For tandem or multi‑pass drawing in a single setup
Long‑span straightener integration – In‑line straightening head capable of correcting bends over 17 m lengths
Automated material handling – Extended infeed and outfeed tables with roller supports to prevent sagging
Applications That Demand 17‑Meter Lengths
Industry | Component | Why 17 m Matters |
Aerospace | Hydraulic system tubing, fuel lines | Seamless runs from wing to fuselage |
Oil & gas | Instrumentation tubing, downhole control lines | Continuous lengths for wellhead equipment |
Industrial automation | Linear guide rails, shafting | Single‑piece rails for long‑travel gantries |
Hydraulics | Cylinder tubes for long‑stroke presses | Eliminates welded extensions |
Transportation | Structural sections for railcars, truck frames | Fewer joints, higher strength |
Medical equipment | MRI table guide rails, imaging system frames | Smooth, joint‑free motion surfaces |
Core Technologies for Long‑Length Precision
Closed‑loop force & position control – Maintains consistent drawing speed and tension over entire 17 m stroke
In‑process laser measurement – Real‑time OD/wall thickness verification at multiple points along the length
Anti‑buckling guide system – Supports the drawn product to prevent sag or bow during exit
Automatic lubrication – Ensures uniform film thickness over extended contact surfaces
Full data logging – Position‑specific dimensional data for quality certification of extra‑long products
Example Production Scenarios
Material | Starting Size | Finished Size | Application |
Stainless 316 | 25 mm OD x 2.5 mm wall, 18 m | 22 mm OD x 2.0 mm wall, 17 m | Offshore instrumentation line |
Aluminum 6061 | 50 mm diameter bar, 17.5 m | 45 mm diameter bar, 17 m | Linear actuator shaft |
Carbon steel 1045 | 80 mm OD x 8 mm wall, 18 m | 75 mm OD x 6.5 mm wall, 17 m | Hydraulic cylinder tube |
Benefits of Choosing a 17‑Meter Drawbench
Reduced welding and joining costs – Eliminate multiple weld joints and associated inspection
Improved fatigue life – No weak points from butt welds in long fluid or structural components
Higher material yield – Cut exactly to customer lengths from a single drawn piece
Competitive differentiator – Few suppliers offer true 17‑m precision cold drawing
Integration Considerations
A 17‑meter drawing line requires more floor space:
Total line length (with infeed, pointer, die area, carriage travel, outfeed, straightener, cut‑off) – approximately 25–30 meters
Ceiling height allowance for overhead crane or bar handling
Foundation requirements – reinforced concrete for heavy‑duty machines
Available Drive Configurations
Drive Type | Best For | 17‑Meter Suitability |
Hydraulic | Soft alloys, surface‑critical extra‑long tubes | Excellent – smooth force, no distance‑based force drop |
Chain‑driven | Ferrous materials, high‑speed production | Good – needs robust chain tensioning over long distance |
Servo‑electric | Cleanroom, energy‑sensitive applications | Limited – high torque requirements for long stroke |
Conclusion
A 17‑meter drawing length cold drawing machine is a specialized asset for manufacturers serving aerospace, oil & gas, industrial automation, and heavy hydraulics. By producing extra‑long precision tubes and bars in a single draw, you reduce downstream joining operations, improve product reliability, and open new markets that demand seamless, ultra‑long components.
