Product Description
1. Multi-Functional Compound Machining Capability
Integrated Turning & Milling: Combines CNC lathe and milling functions in a single machine, enabling complex operations like contouring, threading, drilling, and 3D surface machining without repositioning the workpiece.
X/Z/Y-Axis Configuration: Supports multi-axis contour control for intricate geometries, ideal for aerospace, automotive, and precision mold components.
BMT55 Power Turret: 12+ tool stations with rapid indexing (<0.3 sec), ensuring seamless transitions between turning, milling, and drilling operations.
2. High-Rigidity Structure for Heavy-Duty Applications
Roller Guide Rails: Enhanced rigidity and vibration damping for high-speed machining (up to 6,000 RPM spindle) while maintaining ±0.005 mm positioning accuracy .
Swing Over Bed: 600 mm | Max Turning Diameter: 460 mm: Accommodates large-diameter workpieces, suitable for shafts, flanges, and hydraulic components.
A2-8 Belt-Type Mechanical Spindle: 72 mm bar through-hole supports long-bar machining with minimal deflection.
3. Precision-Optimized Design
Taiwan/Japan/German Precision Components: High-quality bearings, ball screws, and servo motors ensure repeatability (±0.003 mm) and extended machine lifespan .
Hydraulic Tailstock: Stabilizes long workpieces during heavy cutting, reducing deformation risks.
4.Flexible CNC System Compatibility
Multi-Brand Support: Optional FANUC, SIEMENS (SINUMERIK), SYNTEC, KND, GSK systems cater to diverse client preferences, from high-speed 5-axis machining (SIEMENS 840D) to cost-effective solutions (GSK) .
User-Friendly Interface: Supports advanced interpolation algorithms (e.g., linear/circular) for smooth toolpath execution .
5. Industry-Specific Advantages
Automotive & Aerospace: Capable of machining hardened materials (e.g., titanium, Inconel) with Y-axis milling for slots/keyways.
Energy Sector: Efficient for large valve bodies and turbine components due to 320 mm swing over carriage.
6. Customizable Configurations
Modular Design: Optional add-ons include chip conveyors, coolant systems, and C-axis for live tooling.
Energy Efficiency: Optimized servo drives reduce power consumption by 15-20% compared to traditional models.
