High-Accuracy Gun Drilling Machines for Deep Hole Fabrication

Overview

The CNC Dual Axis Gun Drilling Machine is a specialized solution designed for precision deep hole drilling in workpieces requiring extreme accuracy and surface finish. Engineered for hole diameters from 3mm to 50mm and depths up to 2,000mm, this machine combines advanced CNC controls with a rigid mechanical structure to achieve straightness within 0.1mm/100mm and surface roughness ≤Ra 0.4μm.

Features

Dual Axis Synchronization: Independent X/Z axis motion with high-resolution linear scales (0.001mm feedback), ensuring precise hole positioning and depth control.

High-Pressure Coolant System: 200-bar coolant pump with filtration (5μm absolute rating), efficiently flushing chips and cooling the cutting edge during deep penetration.

Vibration-Damping Design: Mineral cast base and anti-resonance spindle housing reduce machining vibrations by 60%, critical for maintaining hole quality in long-depth drilling.

Advanced Tool Monitoring: Load cell-based torque sensor and spindle speed feedback, detecting tool wear and breakage in real-time to prevent workpiece damage.

User-Friendly Interface: Fanuc 0i-MF control with 3D drilling path visualization, supporting both G-code programming and conversational setup for complex hole patterns.

Application

Ideal for industries demanding precision deep hole fabrication:

Firearms Production: Drilling rifle barrels and shotgun bores with consistent diameter and twist rate, meeting SAAMI and CIP ballistic standards.

Hydraulic Systems: Machining high-pressure lines in servo valves and cylinder blocks, ensuring leak-free performance under 3,000 PSI operating pressure.

Aerospace Components: Drilling cooling holes in turbine blades and structural titanium alloys, compliant with AS9100D aerospace quality requirements.

Mold & Die Making: Creating ejector pin holes and conformal cooling channels in injection molds, improving cycle times and part quality.The machine supports both single-spindle and twin-spindle configurations, enabling parallel drilling for increased productivity in multi-hole workpieces.
