Background del cliente<\/strong><\/strong><\/h2>\n\n\n\n

The customer is a bridge steel fabrication plant in East Europe. Their production requires both standard tube cutting and heavy structural section processing. As project-type orders increased, outsourcing became expensive and less predictable due to logistics and subcontractor scheduling. The customer wanted to bring cutting in-house with a solution that could handle a very wide size range while supporting bevel cutting for welding preparation.<\/p>\n\n\n\n

Challenges & Goals<\/strong><\/strong><\/h2>\n\n\n\n
    \n
  • High outsourcing cost: most structural profiles were processed by subcontractors.<\/li>\n\n\n\n
  • Wide size range: from 40\u00d740 mm square tube to 640\u00d7640 mm square sections, up to \u00d8650 mm round tube; bar length up to 12,100 mm and weight up to 3,000 kg.<\/li>\n\n\n\n
  • Multiple processes required: straight cut-off, hole cutting, and bevel cutting for welding preparation.<\/li>\n\n\n\n
  • Target direction: replace outsourcing with in-house processing, validated by cutting tests based on the customer\u2019s drawings.<\/li>\n<\/ul>\n\n\n\n

    SteviS Solution & Key Configuration <\/strong><\/strong><\/h2>\n\n\n\n

    1) 670\u00d7670 mm heavy-duty precision 3-chuck clamping: selected to cover both small tubes (40\u00d740 mm) and large structural sections with stable holding.<\/p>\n\n\n\n

    2) BOCHU bevel cutting control (per contract BOM): chosen to enable bevel tool paths and control logic for welding preparation; BOCHU provides reference solutions for heavy tube\/structural cutting with 3-chuck delivery and bevel capability.<\/p>\n\n\n\n

    3) 12 kW Raycus (CE) fiber laser: provides power margin for carbon steel cutting in heavy-duty applications (exact model and nameplate as per contract).<\/p>\n\n\n\n

    4) 12 m semi-automatic loading & unloading: aligned with 12,100 mm profile length to simplify handling of long and heavy materials.<\/p>\n\n\n\n

    5) Process coverage: cut-off + holes + bevel cutting on one machine, reducing inter-process transport and waiting.<\/p>\n\n\n\n

    Delivery & Implementation Timeline<\/strong><\/strong><\/h2>\n\n\n\n
      \n
    • Sep 2025 | PO placed: confirmed size range, maximum length\/weight, and site layout constraints.<\/li>\n\n\n\n
    • Mid-Jan 2026 | FAT (planned): cutting verification using representative parts\/drawings, focusing on 40\u00d740 mm cutting stability, bevel geometry, hole accuracy, and long-bar cutting consistency.<\/li>\n\n\n\n
    • Early-Feb 2026 | Shipment (planned): rail transportation.<\/li>\n\n\n\n
    • Mar 2026 | Arrival (estimated): positioning, utilities hookup (power\/air\/exhaust).<\/li>\n\n\n\n
    • Commissioning | ~1 month: joint delivery by China-based engineers and local engineers in East Europe.<\/li>\n\n\n\n
    • Training: operation, daily maintenance, and practical tips (including key inspection points and consumables).<\/li>\n\n\n\n
    • Acceptance: cutting tests strictly based on the customer\u2019s drawings.<\/li>\n<\/ul>\n\n\n\n

      Results & Benefits (Stage-Based; Before\/After)<\/strong><\/strong><\/h2>\n\n\n\n

      Note: This case is currently at the \u201cPO placed, FAT\/installation pending\u201d stage. The following items define the target outcomes and acceptance logic; final results will be confirmed after FAT, on-site acceptance, and the first month of production.<\/p>\n\n\n\n

        \n
      • Make-or-buy shift: from outsourcing structural cutting to primarily in-house laser cutting, reducing dependency on subcontractor capacity.<\/li>\n\n\n\n
      • One-machine coverage: from separate solutions for tubes vs. structural sections to one integrated machine covering the required range.<\/li>\n\n\n\n
      • Process consolidation: from distributed operations to cut-off + holes + bevel on one platform.<\/li>\n\n\n\n
      • Lead-time control: from subcontractor scheduling risk to in-house planning control.<\/li>\n<\/ul>\n\n\n\n
