Product Information

This machine tool is a three‑axis CNC gun drilling machine, primarily used for machining cylindrical holes via the external chip‑removal (gun‑drilling) method. It is a deep‑hole machining device in which the cutting tool and tool holder rotate while simultaneously performing feed motion. The machine is characterized by its ability to achieve excellent dimensional accuracy and surface finish in a single pass. In addition to through‑holes, it can also machine stepped holes, blind holes, tapered holes, semi‑circular holes, interrupted holes, and holes in laminated plates.
The worktable’s horizontal movement, the crossbeam’s vertical movement, and the tool feed are all driven by servo‑driven systems that provide stepless speed regulation. The spindle also features stepless speed control, ensuring precise and reliable motion. Workpiece clamping is accomplished with a hydraulic clamping device, which is operated by a dedicated hydraulic power unit. This machine tool represents the optimal choice for modern deep‑hole machining and is widely employed in the precision machining of shallow holes and specialized hole‑forming operations.
The machine tool bed is made of high-quality cast iron, offering excellent rigidity. It employs high-precision ball‑type linear guides and ball screws for transmission, ensuring superior accuracy retention. All operations are controlled via CNC with digital display, enabling safe, quick, and stable workpiece clamping and operation. It is primarily used for deep‑hole machining of large diameters in industries such as mold making, automotive, defense, aerospace, and mining machinery.
This series of machine tools can be customized to meet customer requirements.
