Advanced Turning System
Swiss-Style Turning Technology
The OTM-4800CT is a dedicated Swiss-style turning center, optimized for machining challenging materials like copper and alloy steels. Its four independent 2-axis tooling pods enable advanced techniques such as pinch turning and simultaneous rough and finish passes, ensuring tight control over chip load, heat distribution, and tool wear. This design eliminates deformation and chatter, delivering superior dimensional accuracy and surface finish for long, slender projectiles.
- Technology: Swiss-style turning with multi-axis tooling for complex geometries
- Outcome: Exceptional concentricity and repeatability for mission-critical components
- Applications: Solid copper bullets, hardened steel penetrators, and similar precision parts
FANUC 30i Control System
Powered by the FANUC 30i CNC control platform, the OTM-4800CT offers nano-resolution motion control, advanced toolpath optimization, and real-time diagnostics. This high-performance system supports complex multi-axis operations, custom macros, and seamless integration with automation, ensuring precision and reliability in 24/7 production environments. The user-friendly interface simplifies programming and operation, reducing setup times and enhancing productivity.
- Features: Ultra-fast processing, multichannel support, extensive programming flexibility
- Benefit: Enables high-speed, high-precision machining with minimal operator intervention
- Reliability: Built-in diagnostics and FANUC’s global reputation for durability
High-Pressure Coolant and Scrap Management
The OTM-4800CT features a 250 PSI high-pressure coolant system that delivers powerful, directed flow to the cutting zone, improving chip evacuation, maintaining temperature stability, and extending tool life, especially for tough materials like copper and steel. An industrial-grade chain-type conveyor efficiently removes chips and stringers, preventing buildup and ensuring a clean machining environment. The fully sealed enclosure contains coolant spray, while the coolant return system filters and recirculates for reduced maintenance.
- Coolant System: 250 PSI high-pressure flow for optimal chip evacuation and tool longevity
- Scrap Conveyor: Chain-type system handles ferrous and non-ferrous materials, directing scrap to a collection bin
- Benefit: Enhances machining performance and supports continuous operation
Automated Part Offload
The OTM-4800CT’s automated part offload system ensures gentle, reliable handling of finished components. A spinning pneumatic clamping sub-spindle grips the part during cut-off, preventing deflection or marring. After separation, the sub-spindle transfers the part to a discharge slide and exit conveyor belt, preserving orientation for downstream processes and enabling unattended, lights-out production.
- Mechanism: Pneumatic sub-spindle and conveyor for secure part handling
- Outcome: Eliminates damage and supports continuous, automated production
- Applications: Ideal for high-volume projectile manufacturing with minimal operator oversight
Key Features
