Precision Machining for Steel Production & Wire Forming Equipment
Machined to Endure — High-Durability Components for the Heart of Steel
In the heavy-duty world of steel production and wire forming, precision matters just as much as power. Components face abrasive media, thermal stress, and high rotational loads — often under 24/7 operation. Downtime is costly. Accuracy and durability are non-negotiable.
With 20+ years of CNC experience, we deliver precision-machined components for rolling mills, wire drawing machines, straighteners, coil feeders, shearing lines, gearboxes, and take-up systems used across steel, alloy, and metal processing lines.
✔ Machining Challenges in Steel & Wire Equipment Parts
Working with parts that operate under high torque, temperature, wear, and misalignment tolerance brings significant challenges:
- Large & long components: Shafts, rolls, and mandrels up to 2 meters in length require high-straightness and balancing.
- Wear resistance: Surfaces in contact with steel wire or billets must resist abrasion and galling.
- High hardness materials: Carbide inserts, tool steels, and hardened bearing surfaces demand post-heat treat machining.
- Repeatability in harsh environments: Sealing surfaces and bearing fits must be held despite thermal cycles and shock loads.
- Surface finish & geometry: Polished surfaces are essential for guiding wire or rolling steel without damage or scratch.
✔ Key Components We Specialize In
| Component | Application | Features |
|---|---|---|
| Work Rolls & Guide Rolls | Cold/hot rolling lines | OD grinding, dynamic balancing, hardened surface |
| Wire Drawing Dies / Die Holders | Wire pulling lines | Concentricity < 0.01mm, wear-resistant materials |
| Mandrels / Arbors | Slitting, coiling | Hardened and ground, matched to gear shaft systems |
| Straightener Rollers | Wire, rod, or strip lines | Polished to Ra < 0.2μm, multi-groove CNC turning |
| Gear Housings / Transmission Blocks | Steel machinery drive | Surface-milled, flatness < 0.01mm |
| Shear Blades / Slide Plates | Cutting & handling | Tool steel, vacuum heat treat, lapped edge finish |
| Drive Shafts / Couplings | Rolling or feeding systems | Keyed + ground to ±0.005mm, hardened surfaces |
✔ Materials & Treatments We Use
| Material | Use Case | Surface/Heat Treatment |
|---|---|---|
| 42CrMo4 / SCM440 | Rolls, shafts, mandrels | Induction hardened (HRC 55+), ground OD |
| Tool Steel (H13, D2, SKD11) | Blades, guiding tools | Vacuum heat treatment, cryogenic optional |
| Alloy Steel (8620, 20CrMnTi) | Gear shafts, couplings | Carburized + gear grinding |
| Tungsten Carbide / Inlay | Dies, guides | Brazed inserts, finish lapped |
| GCr15 / SUJ2 | Bearings and rotary rings | Through hardened + precision ground |
| Stainless Steel (SUS304, 410) | Corrosion-prone equipment | Polished + passivated |
We also provide chrome plating, nitriding, black oxide, and PTFE or ceramic coatings depending on wear/friction needs.
