Dezhou Guanlu CNC BTA & Gun Drilling Combination Machine

Main Features of the Machine

This machine is a combined CNC deep hole drilling machine integrating gun drilling and BTA drilling in one unit. It is designed for efficient and precise machining of deep, coaxial holes in shaft-type workpieces, offering high versatility and excellent cost performance.

The machine adopts a single-spindle structure, with both gun drilling and BTA drilling processes sharing the same spindle. This design ensures high coaxial accuracy and stable machining performance while simplifying the overall structure of the machine.

Gun drilling is used for small- and medium-diameter deep holes, while BTA drilling is applied to medium- and large-diameter deep holes, allowing the machine to cover a wide range of hole sizes. Switching between the two drilling methods is realized through manual tool change and oil circuit switching, providing flexible process selection according to different machining requirements.

By combining two deep hole drilling processes into a single machine, this solution effectively reduces equipment quantity, factory floor space, and overall investment, while lowering production costs and improving production efficiency. It is an ideal choice for manufacturers seeking high efficiency, flexibility, and economical deep hole machining solutions.
