Benefits for Metal Cutting Manufacturers

The APEC G Series provides metal cutting manufacturers with the stability, rigidity, and high accuracy needed to machine large parts with confidence. By combining advanced spindle technology, linear motor drives, and dual ball screws, the G Series enables cycle time reduction while achieving ultra-fine surface finishes. For aerospace and mold & die shops, this means producing lightweight, structurally sound components that meet the highest quality requirements.

  • Stability & Rigidity: U-shaped structure ensures cutting forces flow directly into the foundation for consistent precision.
  • High Accuracy: Balanced machine design minimizes vibration and thermal deformation for repeatable accuracy.
  • Ultra-Fine Surface Finishes: Direct-drive head and optimized coolant systems deliver contouring quality required in aerospace.
  • Cycle Time Reduction: Linear motors and high feed rates improve throughput on complex, oversized parts.
  • Reliability & Productivity: Robust construction and water-cooled ball screws maintain accuracy under long production runs.

With the APEC G Series, manufacturers gain a machine solution that improves part quality, reduces scrap rates, and enhances overall shop efficiency.

Key Features

  • Large-Format Gantry Design – Optimized for oversized aerospace structures and molds, providing rigidity and dynamic stability.
  • One-Piece U-Shaped Structure – Shortest transmission path for cutting forces, reducing deflection and vibration.
  • Linear Motor Drives (X/Y) – High-speed axis motion up to 60 m/min with zero transmission loss for fast contouring.
  • Dual Ball Screws with Hollow Water Cooling (Z-Axis) – Precise thermal deformation control for heavy vertical loads.
  • Ductile Iron Ram & Saddle – Maximum damping for vibration-sensitive aerospace machining.
  • Direct Drive 2-Axis Head – High torque, high resolution, and low error for accurate 5-axis contouring of curved surfaces.
  • Flexible Spindle Options – High-speed spindles (20,000–24,000 rpm) for aluminum alloys or high-torque spindles for tougher materials.
  • Efficient Chip Evacuation & Coolant Systems – Designed for continuous operation on large aluminum and composite structures.
  • Fully Enclosed Work Zone – Safe and clean environment for both high-speed and heavy-duty cutting applications.

Ideal Cutting Applications

  • Aerospace Structures – Machining of large wings, fuselage panels, spars, ribs, bulkheads, and frames.
  • Engine Components – Precision machining of housings, casings, and complex turbine parts.
  • Mold & Die – Large-format injection molds, stamping dies, and precision forming tools.
  • Energy & Transportation – Heavy-duty machining for wind turbine hubs, locomotive components, and industrial machinery bases.
  • Automotive – Large die sets, prototype tooling, and high-accuracy body structure components.

The APEC G Series is especially effective in aerospace machining of aluminum alloys and thin-wall structures, where accuracy, rigidity, and speed are critical to success.
