Large-Part CNC Machining Solutions
CNC Double Column Machining Centers
Double-column CNC machining centers for milling large, long and heavy components, with configurations selected according to the workpiece and machining requirements.
A CNC double-column machining center uses two vertical columns connected by a crossrail above the worktable. This bridge-style structure provides the working envelope required for machining large components, dies, moulds and machine frames.
Machine selection depends on the workpiece dimensions, weight, material, required accuracy, machining operations and tool-access directions. Explore more CNC machine solutions or send your part drawing for technical review.
What is a CNC double-column machining center?
A double-column machining center is a bridge-style CNC milling machine designed around two columns and a crossrail. Depending on its configuration, the table, bridge or machining head moves along the controlled axes to machine large workpieces.

Installation and lifecycle requirements
The foundation, floor loading, electrical supply, compressed air, lifting equipment, coolant, chip management, tooling, workholding, training, maintenance and spare-parts requirements must be confirmed from the official documentation for the selected model.
Send the workpiece drawing, material, dimensions, weight, machining operations, tolerances and production quantity to SAKKARY MACHINERY for technical machine selection.
Questions we are asked
What parts can a CNC double-column machine process?
It is commonly used for large dies, moulds, machine structures, plates and heavy engineering components within the verified capacity of the selected model.
What dimensions are important when selecting the machine?
The workpiece length, width, height and weight must be compared with the table size, load capacity, distance between columns and axis travels.
Can the machine perform multi-face machining?
Some configurations support angular, universal or interchangeable heads for multi-face machining. This capability must be verified for the selected model.
What site preparations are required?
Requirements may include a reinforced foundation, suitable floor loading, electrical power, compressed air, lifting equipment and sufficient installation and maintenance space.
