🛠 Machine Structure & Working Principle

This CNC deep hole drilling machine adopts a gun drilling process, where both the tool and workpiece rotate relative to each other while the tool performs axial feed.

The hydraulic clamping system automatically centers and clamps the workpiece

The guide bush system ensures high accuracy in deep hole drilling

The linear guideways provide smooth and precise movement

The servo feed system with ball screw enables stepless speed control

❄️ High-Pressure Cooling System for Gun Drilling

The machine is equipped with a professional high-pressure coolant system, essential for stable gun drilling operations:

High-pressure pump system (up to 10 MPa)

Efficient chip removal system

Oil cooling unit

Precision filtration system (20μm)

This ensures excellent surface finish and extends tool life during deep hole drilling.
