APEC G-800T & TR Compact 5-Axis Gantry Vertical Machining Centers

The APEC G-Series, including the G-800T and G-800TR, is engineered for workpieces that demand full 5-axis simultaneous machining across industries such as aerospace, mold and die, and automotive. These compact gantry machining centers deliver high rigidity, accuracy, and efficiency in one streamlined platform. The “T” designation indicates a tilting table for maximum 5-axis machining flexibility, while the “TR” designation adds rotary capability, enabling continuous 5-axis contouring of complex geometries in a single setup.

Benefits of the G-800T for Metal Cutting Manufacturers

  • Combines 5-axis milling and turning in a single setup with C-axis speeds up to 1,000 rpm.
  • Shortens cycle times on parts requiring both rotational contouring and precision surface finishing.
  • Delivers high rigidity and ultra-fine surface finishes, ideal for aerospace impellers, blisks, and engine blades.
  • Reduces workholding complexity and setup changes, improving throughput and reliability.

Benefits of the G-800TR for Metal Cutting Manufacturers

  • Dual-supported rotary tilt table ensures maximum stability and accuracy in heavy or long-cycle machining.
  • Seamless integration with Multi-Pallet Pool (MPP) automation for extended unmanned operation (up to 18 pallets).
  • Optimized for complex molds, stamping dies, and large structural aerospace components where repeatability is critical.
  • High precision in 5-axis contouring enables superior profile accuracy and dimensional consistency.

Key Features of the G-800T

  • 20,000 rpm HSK63T spindle with up to 123 Nm torque for high-speed aluminum or titanium machining.
  • Direct-drive torque motors powering the A/C axes for fast tilting and continuous rotation.
  • Integrated turning on the C-axis for hybrid part production.
  • Compact gantry U-frame design eliminates workpiece weight influence and maximizes rigidity.
  • BLUM tool and workpiece probing for reduced setup time and process reliability.

Key Features of the G-800TR

  • 20,000 rpm HSK63A spindle with 55 Nm torque, cooled by independent chiller for thermal stability.
  • Symmetrical dual-support rotary tilt table for enhanced force distribution.
  • ±120° A-axis tilt and continuous C-axis rotation for simultaneous 5-axis machining.
  • Automation-ready design with optional MPP pallet pool.
  • Heidenhain iTNC640 control with TCPM, 3D compensation, and advanced 5-axis contouring functions.
