  • 130mm Spindle Diameter: The core of the machine's rigidity. A 130mm spindle supports heavy-duty boring and milling without chatter, making it ideal for deep-hole operations in large castings or weldments.
  • 3000mm X-Axis Travel: Provides an extensive work envelope, allowing you to machine long components in a single setup, which reduces handling time and minimizes cumulative alignment errors.
  • Fanuc 18-MB Control: A proven, stable control system. Its widespread adoption ensures operator familiarity and straightforward integration into existing Fanuc-based production lines.
  • 4-Axis with Scales: Includes feedback scales on the 4th axis for high-precision indexing—critical for parts requiring angular features or multi-sided machining without repositioning the workpiece.

Tooling Match and Part Fit

The HNK HB-130 is a versatile platform capable of adapting to various industrial requirements. Its structural design is well-suited for:

  • Automotive & Heavy Equipment: Machining large engine blocks, transmission housings, and chassis components.
  • Aerospace: Working on large structural frames and tooling fixtures that require high dimensional accuracy.
  • Mold & Die: Handling large-format mold bases that require deep pocket milling and precision boring.
  • General Heavy Engineering: Boring and milling of industrial pump housings, gearboxes, and large-scale valves.

The 1800 x 2000 mm table provides a stable platform for large fixtures. When evaluating part fit, ensure your workpiece weight distribution remains within the table's load capacity to maintain 4th-axis indexing accuracy.

Evaluating Machine Selection

When comparing this used HNK HB-130 against other machines, the decision should hinge on the balance between your part size and the required spindle torque. The 130mm spindle is optimized for heavy material removal. While this machine may be over-specified for smaller, high-speed parts, it is the ideal solution for production bottlenecks involving "chatter" on large parts or the inability to reach deep features. The rigid spindle and 700mm W-axis (quill travel) are the specific features that will resolve those production constraints.

Is This Machine Right for Your Shop?

This machine is a strong fit for your shop floor if:

  • You are currently outsourcing large-part machining due to capacity constraints.
  • Your production schedule is limited by equipment that cannot handle long-travel workpieces in a single setup.
  • You require a reliable, proven platform (Fanuc) that can be integrated into your shop immediately.
  • You need to expand your boring and milling capabilities without the lead times associated with new equipment.

    Frequently Asked Questions

    Q: Can the 130mm spindle handle heavy-duty steel milling?

    A: Yes, the 130mm spindle is designed for high-torque applications. It provides the necessary rigidity for heavy milling and boring in steel and cast iron, provided that appropriate tooling and feed rates are utilized.

    Q: Is the 4th axis suitable for high-precision indexing?

    A: Yes, the machine is equipped with scales on the 4th axis. This feedback system allows for precise angular positioning, which is essential for parts requiring multi-sided machining in a single setup.

    Q: How does the 700mm W-axis travel affect my tooling choices?

    A: The 700mm W-axis (quill travel) provides significant reach for deep-hole boring. This allows you to use shorter, more rigid boring bars, which minimizes vibration and improves surface finish on deep internal features.

    Q: What type of factory environment is this machine best suited for?

    A: This machine is best suited for job shops, heavy manufacturing facilities, or OEM production lines that process large, complex components requiring a mix of boring, milling, and drilling operations.
