Speed Meets Precision: How the VMC855 Vertical Machining Center Conquers Complex Molds & Aerospace Parts


Overview
The VMC855 vertical machining center redefines efficiency with its 800×550×550mm tri-axis travel and 600kg table load. Powered by a 10,000rpm BT40 spindle and 48m/min rapid feeds, this 11kW powerhouse achieves ±0.005mm repeatability while milling hardened steel (HRC52) at 8m/min. From aluminum aircraft brackets to titanium medical implants, its 24-tool ATC and FANUC control deliver 5-axis readiness—proving that high-speed machining needs no compromise on rigidity or precision.

Core Applications

  1. Aerospace Bracket Mega-Milling
    Machine 7075-T6 aluminum brackets at 16m/min feed rates. The 35mm HIWIN roller guides absorb vibration during deep-pocketing, while C3-grade ballscrews ensure 0.008mm positioning accuracy—critical for Boeing 787 subcontractors .

  2. Medical Implant Micro-Finishing
    Achieve Ra 0.2μm on spinal fusion cages. Direct-drive spindle + oil-cooling limit thermal drift to 3μm/m during 18-hour runs—Swiss medtech firms report 98% first-pass yield .

  3. Automotive Die Resurrection
    Revive HRC52 stamping dies with 0.3mm stepover precision. Y-axis quad-rail design prevents deflection during trochoidal milling, extending tool life by 40% in EV battery projects .

Engineering Superiority

  • Rigidity Redefined: Monolithic Meehanite casting (5,500kg) with cross-ribbed column boosts natural frequency by 35%, suppressing chatter in 300mm-deep slots .

  • Zero-Downtime Automation: 24-tool ATC exchanges cutters in 2.2 seconds (T-T). Spiral chip conveyors handle 120kg/hr swarf .

  • Thermal Warfare: Pre-tensioned screws + NSK P4 bearings reduce heat-induced error to 2.5μm/m—Vietnamese coastal factories log 12,000 hours without recalibration .
