Features
While siblings handle bulkier tasks, the TC640 thrives in the microcosmos – where 0.5mm end mills dance at 20,000-24,000 RPM to craft:
- Medical Miracles: 200+ titanium bone screws/hour, Ra 0.2μm finishes (no polishing)
- Electronics Euphoria: 5G heatsinks with 0.015mm slot tolerances – 37% faster than “high-speed” rivals
- Automotive Agility: EV battery plates swapped from aluminum to copper in 8s (tool #23 ↔ #17)
Why Machinists Cheat on Their Old Machines
- Speed Without Tears: 0.8s tool swaps (tested 2.1M cycles) + collision sensors that save $3k/month in broken tools
- Space Whisperer: 2.1m² footprint – smaller than a Tesla Model 3, outputs like a Hummer
- Material Polyglot: From aerogel molds to zirconium implants, it speaks 50+ alloys fluently
Optional
Application
