|---|---|
The Three-Axis Composite Deep Hole Drilling Machine is a state-of-the-art solution designed to meet the extreme precision and productivity demands of deep hole machining. Combining Gun Drill and BTA (Boring Trepanning Association) technologies, this machine handles hole diameters from 3mm to 300mm and depths up to 5 meters, delivering unmatched straightness (≤0.1mm/m) and surface finish (Ra ≤1.6μm) in materials ranging from aluminum to hardened tool steel (55 HRC).
Dual Technology Integration:
Gun Drill Module: For small diameters (3-50mm), with high-pressure coolant (300 bar) and spindle speeds up to 15,000 RPM for deep holes in aerospace titanium components.
BTA Module: For large diameters (50-300mm), featuring a trepanning system that removes core material, reducing machining time by 40% for oil & gas pipeline valves.
Precision Motion Control:
Three-axis CNC (X/Y/Z) with linear scales (0.001mm resolution) and thermal compensation, ensuring hole positioning accuracy within ±0.02mm.
Hydrostatic guideways and backlash-free ball screws (C3 class) eliminate vibration during high-torque BTA operations (spindle power up to 50kW).
Advanced Chip Management:
Automated chip conveyor with 5μm filtration, preventing tool clogging and maintaining coolant purity for extended tool life (20% longer than standard systems).
Pressure-sensitive sensors detect chip buildup in real-time, triggering automatic retraction and flushing cycles.
Critical for industries requiring deep hole precision:
Oil & Gas Exploration: Drilling high-pressure boreholes in subsea wellheads, compliant with API 6A and NACE MR0175 standards for sour gas environments.
Heavy Machinery: Machining hydraulic cylinder bores and transmission shafts for construction equipment, ensuring leak-free performance at 3,500 PSI.
Aerospace Structures: Creating deep cooling channels in aircraft engine casings, supporting heat dissipation in high-temperature flight conditions.
Process Optimization: In-house application engineers develop custom drilling protocols (speed, feed, coolant pressure) for your specific material, reducing cycle times by 30%.
Quality Assurance: Integrated air gauge measurement system provides real-time hole diameter feedback, eliminating post-drilling inspections for critical components.
Global Service Network: 24/7 remote diagnostics and local technicians in 12 countries, ensuring minimal downtime for complex deep hole operations.
