A CNC Double Column Machining Center is a type of computer numerical control (CNC) machine tool that is specifically designed for high-precision machining of large workpieces. These machines are characterized by their large work envelopes and high rigidity, which allow them to machine large and heavy parts with precision and accuracy. The name “double column” refers to the two large vertical columns that support the spindle and the table of the machine.

A double column machining center typically features a spindle that moves in the Z-axis direction and a table that moves in the X and Y axes. The machine can handle a wide range of materials such as metals, plastics, and composites, and can be used for drilling, milling, boring, tapping and other machining operations.

CNC double column machining centers are used in a variety of industries such as aerospace, automotive, construction equipment, and energy, where large and heavy parts need to be machined with precision and high productivity. They are also used for manufacturing of molds, dies and many more.

The double column design of the machine provides higher stability, rigidity and precision as compared to single column machining center. With high precision and high speed, this machine can complete large workpieces in a short time, also it can work on both large and small parts. They are also equipped with advanced CNC control system, which allows for complex, multi-axis machining operations and automatic tool change.
