Benefits for Metal Cutting Manufacturers

The APEC GM Series provides manufacturers with the ideal balance of high rigidity and high-speed precision, ensuring performance and repeatability in machining large dies, molds, and heavy structural components. Its advanced thermal management, low center of gravity, and direct drive head allow shops to maintain both productivity and quality, even on complex 5-axis machining tasks.

  • Rigidity & Stability: Box-in-box design and casting-made base ensure rigidity for large stamping dies and molds.
  • High Accuracy: Linear motor drives minimize backlash and ensure smooth axis motion for precision cuts.
  • Surface Finish Quality: Direct drive head and advanced coolant systems produce ultra-fine finishes on mold cavities and die surfaces.
  • Cycle Time Reduction: Rapid feed rates up to 60 m/min improve throughput for large parts and tooling.
  • Reliability in Production: Hollow water-cooled ball screws and thermal compensation keep accuracy stable during extended operations.

For die & mold, automotive, energy, and aerospace shops, the GM Series delivers long-term value by reducing scrap, extending tool life, and ensuring parts meet the highest industry standards.

Key Features

  • Box-in-Box Symmetrical Gantry Design – Balances cutting forces, reduces deflection, and maintains high rigidity.
  • Linear Motor Drives (X/Y/Z) – Provides ultra-fast axis motion up to 60 m/min with high acceleration and smooth contouring.
  • Dual Ball Screws with Hollow Water Cooling (Z-Axis) – Ensures concentric motion and thermal stability during vertical machining.
  • Casting-Made Saddle, Ram, and Base – Enhances vibration damping and long-term structural accuracy.
  • Direct Drive 2-Axis Head – High torque, compact design ideal for complex 5-axis mold and die contouring.
  • Closed-Loop Counterbalance System – Maintains rigidity by offsetting gravitational load on vertical axes.
  • Heightened Column with Extended Z Travel – Accommodates large stamping dies, molds, and tall aerospace structures.
  • Efficient Chip Evacuation & Coolant Systems – Keeps cutting zones clear, ideal for long cutting cycles in die & mold machining.
  • Fully Enclosed Work Zone – Improves safety, chip containment, and clean operation.

Ideal Cutting Applications

  • Large Stamping Dies & Tooling – Automotive and appliance dies, precision forming tools, and press dies.
  • Injection & Compression Molds – Large plastic injection molds, die-casting molds, and rubber compression molds.
  • Precision Machining for Energy & Transportation – Oversized turbine hubs, locomotive components, and heavy industrial castings.
  • Aerospace Structures – Thin-wall aluminum structures such as bulkheads, ribs, fuselage frames, and engine housings.
  • Complex 5-Axis Contouring – High-speed machining of mold cavities, curved surfaces, and high-precision contours.
