6-Axis Deep Hole Drilling

The 6-axis dual-spindle deep hole drilling machine is a high-precision and high-efficiency machining system designed for deep hole processing. With a dual-spindle structure, it can drill simultaneously or independently to improve productivity and reduce cycle time. The six-axis control system provides excellent flexibility and positioning accuracy, enabling complex angle and multi-position drilling. Equipped with a high-pressure coolant and chip removal system, it improves tool life and hole quality, and is widely used in aerospace, automotive, mold, and energy equipment manufacturing.

• Maximum drilling depth: 1000 – 2500 mm (customizable)

• Travel range: X-axis 1000–3000 mm, Y-axis 800–1500 mm, Z-axis 1000–2500 mm

• Rotation axis: A axis ± 66 ° , B axis 360° continuous rotation

• Spindle speed: 100 – 8000 rpm

• Spindle power: 15 – 60 kW

• Positioning accuracy: ±0.0 15 mm

• Repeat positioning accuracy: ±0.0 1 5 mm

Application Areas

• Aerospace: integral blade disks, engine casings, complex deep holes in structural parts

• Energy equipment: gas turbines, nuclear power equipment, deep hole oil and gas drilling tools

• Mold manufacturing: injection mold, die casting mold cooling water channel and compound hole processing

• Construction machinery: hydraulic cylinders, main beam deep holes and reinforced structural parts

Product Features
