Double Column Milling Machines

Features:
1. Bed, columns and travel tracks form a solid cast-iron frame structure for high rigidity under hard machining conditions and high table loads.
2. The gantry construction is fully integrated into the machine frame for maximum rigidity.
3. The traverse height is adjustable, ensuring high rigidity even with flat workpieces, since the throat size can be minimized.

Features:


1. Bed, columns and travel tracks form a solid cast-iron frame structure for high rigidity under hard machining conditions and high table loads.

2. The gantry construction is fully integrated into the machine frame for maximum rigidity.

3. The traverse height is adjustable, ensuring high rigidity even with flat workpieces, since the throat size can be minimized.

4. Rigid guides with ground surfaces support the table across the entire travel distance to ensure constant high geometric accuracy.

5. Large setup area with up to 4000mm (more length) in length.

6. Double column milling machines can process work pieces weights up to 8000kg.

7. Main spindle gears with 6 steps for vertical and horizontal operation.

8. Double column milling machines are equipped with weight balancing system for easy movement and precise positioning of the horizontal spindle head.

9. All guideways are protected by telescoping covers or bellows (Optional).

10. The control panel is mounted on a long arm, giving the user maximum positioning flexibility.


Vertical Mill Head and Horizontal Mill Head of Double Column Milling Machines


» Vertical spindle head on height-adjustable traverse can be moved across the entire machining width.
» Easy positioning of the  horizontal spindle on the right column guide on Y axis, and via a compact guideway slide 14 in on the Z-axis.
» Sided machining of the workpiece in vertical and horizontal direction with only one setup.
