Composite CNC Deep Hole Gun Drilling & BTA Drilling Machine (ZSK2108F)

High-Precision Composite Deep Hole Drilling Machine for Gun Drilling & BTA Drilling

The ZSK2108F Composite CNC Deep Hole Drilling Machine is specially designed for precision deep hole machining of shaft-type components. One machine integrates both Gun Drilling and BTA Deep Hole Drilling processes, allowing manufacturers to cover a wide range of hole diameters with high efficiency and lower investment.

By simply changing the tooling, auxiliary fixtures and coolant circuit, the machine can quickly switch between Gun Drilling and BTA drilling, providing excellent flexibility for various production requirements.

Machine Advantages

Dual Drilling Capability

One spindle supports both Gun Drilling and BTA drilling, reducing equipment investment while expanding machining capability.

High Rigidity Structure

The machine bed and major structural components are manufactured from high-quality resin sand castings and undergo double aging treatment to ensure excellent rigidity, vibration resistance and machining stability.

Efficient Coolant System

Equipped with variable-frequency high-pressure pumps, constant-flow pumps, oil chiller, paper filter and chip conveyor to ensure reliable deep hole machining performance.

Precision Servo Feed

The servo-driven ball screw feed system provides smooth, accurate feeding for stable drilling quality and improved tool life.

Reliable Components

The machine adopts internationally recognized components including Siemens CNC system, NSK spindle bearings, TBI ball screws and high-quality electrical and hydraulic components.
