The development of the OKK HX500 reflects current manufacturing demands for machines that combine compact footprint, advanced chip evacuation, fast traverse speeds, ergonomic operation, and high accuracy, making it ideal for industries such as aerospace, electric vehicles (EVs), robotics, and precision industrial production. NIDEC CORPORATION


What Is the OKK HX500?

The OKK HX500 is a dedicated 5-axis horizontal machining center that builds on OKK’s long history of rigid machine tool design. It is engineered to handle complex 5-axis machining tasks while maximizing productivity and reducing setup time. NIDEC CORPORATION

This model features a direct-drive trunnion table, fast tool changing, and sophisticated chip management — all within a relatively compact footprint that fits into modern, space-constrained manufacturing environments. NIDEC CORPORATION


Key Features of the OKK HX500

5-Axis Capability and Rigid Construction

The core of the OKK HX500’s performance is its direct-drive driven A-axis (tilt) and B-axis (slew) coupled with a dual-disk clamp system on the trunnion table. This design reduces backlash and delivers high rigidity for precise and stable 5-axis machining. NIDEC CORPORATION


High Speed and Rapid Traverse

With rapid traverse rates up to 65 m/min on the X, Y, and Z axes and a spindle capable of up to 15,000 min⁻¹, the HX500 minimizes non-cutting time and increases throughput. These specifications support both roughing and high-precision finishing operations on a range of materials. NIDEC CORPORATION


Advanced Chip Evacuation

To maintain machining accuracy and avoid chip buildup, the OKK HX500 employs an inverted table range (–210° to +30°) that allows chips to fall directly into a central trough. Combined with optimized coolant flow, this design supports continuous machining even in inverted conditions, improving coolant effectiveness and reducing cycle disruptions. NIDEC CORPORATION


Compact Footprint and Space Efficiency

Despite its advanced capabilities, the OKK HX500 maintains a compact installation area of approximately 15 m² (2.6 × 5.62 m), making it suitable for shops with limited floor space. This “best-in-class” space efficiency helps manufacturers integrate high-performance 5-axis machining without major layout changes. NIDEC CORPORATION


Ergonomics and Operator Efficiency

The machine’s unique automatic pallet changer (APC) positions the pallet at an ergonomic 1,050 mm loading height, reducing operator fatigue and streamlining workpiece setup. An internal monitoring camera and centralized maintenance interface further support operator productivity. NIDEC CORPORATION

Why the OKK HX500 Matters in 2025

The OKK HX500 addresses several manufacturing trends shaping machine tool purchases in 2025:

  • Complex part machining: Increasing demand for components with multi-surface contours and tight tolerances, common in aerospace, EVs, and robotics. NIDEC CORPORATION

  • Productivity gains: Fast traverses, high spindle speeds, and reduced non-cutting time enable better productivity per shift. NIDEC CORPORATION

  • Ergonomics and space use: Compact design and improved loading ergonomics help manufacturers optimize shop floor operations. https://visitors.emo-hannover.de

  • Chip management: Enhanced chip evacuation minimizes downtime from chip recutting and simplifies long-cycle operations. NIDEC CORPORATION


Conclusion

The OKK HX500 represents a significant advancement in horizontal 5-axis machining centers for 2025. Its combination of rigidity, speed, ergonomic design, and chip control makes it a strong choice for manufacturers looking to improve productivity and precision in complex 5-axis applications.

For shops and factories facing greater demands on cycle time, part complexity, and production flexibility, the OKK HX500 offers a compelling solution backed by OKK’s decades of machine tool expertise. NIDEC CORPORA
