Bridge Type Machining Center - RB Series  

 

With more than 4000 machines installed worldwide, RB-Series is best selling model for Bridge type, Moving Cross-rail 5-Face machining Center. The 5-face machining attachment is automatically changed, and the tools are automatically changed.
In addition to the X, Y, and Z-Axes, the CNC controlled 4th axis for Moving Cross-Rail permits easy machining. In addition, a generous quill stroke allows easy access to cavities and  deep hole cutting.

Ideally suited for Die-Mold and Large component machining, RB-Series offers many advantages in terms of accuracy, less setup time and ease of Unmanned-operation.
 
Circular-section columns for high machining accuracy.

Increased productivity achieved by high-horsepower, high-speed cutting.

Model RB series can be provided with ATC, APC and all units for 5-suface machining use.

High-speed high-power spindle capable of doing a wide range work from roughing to finishing.

High-power (18kw) angular attachment available.
