Vantaggio Jucheng |
| Heavy-Duty Turning |
High-torque CNC turning for machining tough alloy steels into shafts, axles, and cylindrical housings. |
Capable of handling large diameter billets with rapid material removal rates for cost efficiency. |
| Hard Part Machining |
Machining steel after heat treatment (up to ~60 HRC) using PCBN or specialized carbide tools. |
Allows for final sizing after distortion from heat treatment, ensuring high precision. |
| Rettifica di precisione |
Surface and cylindrical grinding to achieve tight tolerances (+/- 0.005mm) and superior surface finishes. |
Essential for bearing surfaces and mating parts in automotive and machinery applications. |
| Elettroerosione e taglio a filo |
Using electrical discharge to cut hardened tool steels for mold making and complex internal features. |
Enables the creation of sharp corners and deep cavities that traditional milling cannot access. |
Fabrication Guidelines for Steel
Strategia di Trattamento Termico:
Steel is often machined in an annealed (soft) state, then heat-treated for hardness, and finally ground or hard-turned to finish size. This workflow balances machining speed with part durability.
Chip Control:
Low carbon steels (like 1018) can be “gummy” and produce long, stringy chips. We use chip-breaking tool geometries and high-pressure coolant to break chips into manageable sizes, preventing bird-nesting.
Surface Protection:
Unlike Aluminum or Stainless, standard steel rusts easily. Parts must be oiled immediately after machining or plated (Zinc, Nickel, Black Oxide) to prevent corrosion during shipping and storage.
Tool Coatings:
We utilize TiCN or AlTiN coated tools to withstand the high heat generated when machining alloy steels, allowing for faster speeds and longer tool life.
