Key Features & Specifications

L-46SDY Turning-Milling Center is a high-precision, robust, and versatile machine tool platform. Its main structure features an integral flat bed and inclined saddle design, providing exceptional rigidity and dynamic stability under heavy cutting conditions. Configured with dual spindles, dual turrets, and dual control channels, the machine operates through a full closed-loop control system with precision linear encoders. This ensures high positioning accuracy and reliable repeatability for critical applications.

The synergy between its rigid mechanical foundation and advanced multi-channel control enables flexible integration of various power tools and turning attachments. This allows for complete machining operations—including turning, milling, drilling, and other processes—in a single setup, significantly enhancing production efficiency and process capability for complex components.

| Spindle System

Dual spindles enable automated loading/unloading for enhanced machining efficiency.

High Precision Synchronous Servo Spindle (maximum speed-6000rpm)
