Gantry Type 5-Axis Machining Center

CU is designed for complex and multi surface contour machining. The series has working capacity ideal for medium-size workpiece and offers superior performance in all aspects of milling - consistency, accuracy, and power, therefore serving as a critical asset to all industries. The upgraded gantry type design presents

compact structure with maximum working area reserved.

Brand New Design with Upgrade Performance brings high precision and high-speed 5-Axis machining

Gantry structure

• Spindle moves in linear axis XYZ, ensuring better machining rigidity

• Gantry moves fully supported in all Y-axis travel, for the best accuracy

• All body made of high- quality Meehanite casting, providing optimal damping of machining vibrations and homogeneous thermal behavior

• Excellent accessibility to working area

The gantry structure offers the best accuracy and rigidity for a 5-axis vertical machining center, allowing high-speed cutting process in complex parts with various materials.
