Description

Product description
The Forceturn series offers a cycle-controlled flat-bed CNC lathe platform for machining large and heavy workpieces. The machine design supports long parts (series up to 5,000 mm) with high geometric stability. The intuitive Fagor control provides teach-in and cycle programming; two electronic handwheels enable manual-style operation and fast setup. A range of options (steady rests, tailstock variants, chip conveyors, turret options) allows configuration to specific production or maintenance tasks.

Highlights
  • Cycle-controlled CNC operation for single-part and batch production
  • 4-station servo-driven tool changer for programmed tool changes
  • Two electronic handwheels for manual operation and fine positioning
  • Infinitely variable spindle speeds with automatic 3-step main gear

Product details
  • Fagor control with intuitive cycle programming and Profile Editor for complex parts
  • Graphical simulation to verify programs prior to machining
  • Large hardened, ground and counter-laminated guides in a massive flat bed
  • Main drive motor rated for heavy workpieces (peak 22 kW, continuous 15 kW)
  • High-performance coolant system and automatic central lubrication included
  • Spindle bore: 85 mm (models 630) or 105 mm (models 800)
  • Heavy automatic 4-station servo tool holder for reliable tool changes
  • Two electronic handwheels on the control panel for quick setup and manual interventions
