Johnford FBMC Series CNC Boring Mills

Built-to-Order Ultra-Heavy Floor-Type CNC Boring Mills Engineered for Unlimited Travel, Extreme Rigidity & Application-Specific Customization

The Johnford FBMC Series represents the pinnacle of floor-type CNC boring mill engineering — purpose-built for manufacturers machining extremely large, heavy, and complex components that demand absolute rigidity and accuracy over long distances. Constructed from massive Meehanite castings (up to 350,000 lbs for large configurations ) and using moving-column X-axis architecture, these boring milling machines deliver exceptional stability for precision machining of aerospace structures, energy components, industrial equipment bases, heavy machinery frames, wind turbine structures, and multi-surface machining applications involving extremely long travel requirements.

Unlike standard production boring mills, every FBMC machine is custom-engineered to the buyer’s exact application—from X-axis travels as short as 236″ to more than 590″ (15 meters) , to custom floor plates, hydrostatic or roller-bearing rotary tables, extended-travel rams, and full automatic attachment changers. This flexibility positions the FBMC Series as a world-class alternative to much more expensive systems from Fermat, TOS Varnsdorf, and Giddings & Lewis, while delivering equal or greater rigidity and long-term accuracy at a more competitive investment level.

Key Features

• Massive Moving-Column Floor-Type Design
  One-piece X-axis base casting with dual rack-and-pinion drive ensures stable movement across travels up to 590″+ (15 meters) while eliminating table overhang.
• Hydrostatic Box-Way or Roller-Way Systems
  Hydrostatic ways in X/Y/Z/B for ultra-smooth motion, zero metal-to-metal contact, and exceptional long-term accuracy (hydrostatic standard on many large configurations) .
• Heavy-Duty 6.3″ Spindle Bar + Massive Ram Construction
  Chrome-moly quill and 20.5″ × 17.7″+ ram cross-sections deliver superior rigidity for deep boring and extended-reach cutting at full spindle power.
• 100 HP Three-Speed Geared Spindles
  High torque at low RPM enables heavy-cut milling, deep boring, and high-load drilling applications.
• Customizable Table Configurations
  • Fixed floor plates of 6m, 10m, 14m, or 15m length
  • Roller-bearing rotary tables up to 55,000 lbs
  • Hydrostatic rotary tables up to 110,000 lbs with V-axis travel
  • Combination fixed + rotary table systems
    (All configurations documented across supplied quotations.)
• Automatic Attachment Changer (Optional)
  Supports 1–4 heads including right-angle, 2-axis indexing, extension heads, and more for complex multi-directional machining.
• 60–120 Tool ATC with Column-Mounted Design
  Heavy-duty arm-type ATC travels with the column for fast tool changes and maintenance access.
• Advanced Axis Control and Feedback
  Heidenhain linear scales on all axes (XYZWV) ensure long-travel accuracy and thermal stability across massive machine structures.
• Fanuc 31iM-B Plus Control System
  High-performance CNC with Manual Guide i, AICC-II contouring, 1,000,000-pulse encoders, and multi-axis simultaneous control for mold-and-die and complex surfacing.
• Integrated Chip & Coolant Management
  Caterpillar conveyors, 250–500 gallon coolant capacity, programmable air blast, and 300 PSI TSC maintain stable cutting conditions for long-cycle operations.
• Operator-Friendly Elevated Cabin
  Operator platforms provide clear line-of-sight to machining zones on machines of this magnitude.
