DRILLSTAR CARBIDE TOOLS ARE WORKING IN MANY PLACES AROUND THE WORLD
Deep Hole Drilling And Boring Machines are specialized CNC machine tools designed to precision machine deep cylindrical holes—ranging from 3mm to 500mm in diameter and up to 20 meters in depth—with unmatched accuracy and efficiency. Combining robust mechanical construction with advanced control systems, these machines utilize technologies like BTA (Boring and Trepanning Association), gun drilling, and ejector drilling to handle the most challenging deep-hole applications in materials such as stainless steel, titanium, and nickel-based superalloys.
Engineered for heavy-duty industrial use, these machines feature rigid cast iron frames, high-precision spindle systems, and automated coolant management, ensuring stable operation and minimal vibration even at extreme depths. Their versatility across drilling, boring, and reaming operations makes them indispensable in industries where deep-hole quality directly impacts component performance and safety.
Heavy-Duty Construction:
Monolithic cast iron bed (weight 10–50 tons) with ribbed reinforcement to dampen vibrations and maintain positional accuracy (±0.05mm over 10 meters).
Hydrostatic or hydrodynamic spindle bearings capable of delivering up to 10,000 Nm torque for machining high-strength materials at low speeds (50–500 RPM).
Precision Control Systems:
CNC multi-axis control (X, Z, C axes) with absolute encoders (resolution 0.001mm) for programmable feed rates (0.01–50 mm/min) and depth positioning.
Laser alignment system for tool and workpiece setup, ensuring hole straightness within 0.1% of depth for ultra-deep bores.
Advanced Coolant Technology:
High-pressure coolant pump (200 bar max.) with filtration (5μm absolute) to ensure clean, high-velocity fluid flow for efficient chip evacuation.
Modular coolant tank systems (500–5,000 liters) with temperature control (±2°C) to prevent thermal expansion errors in long machining cycles.
Tooling Versatility:
Compatible with BTA, gun, and ejector drills, as well as boring bars and reamers, via quick-change tool holders (e.g., HSK-A100, Capto C6).
Automatic tool length and diameter measurement (via touch probes) for seamless tool changes and offset adjustments.
Safety & Automation:
Full enclosure with interlocked doors and chip conveyor systems for operator protection and continuous waste removal.
Integration with IoT sensors for real-time monitoring of spindle load, coolant pressure, and tool wear, enabling predictive maintenance and process optimization.
Aerospace Engine Manufacturing: Machining deep holes in titanium alloy fan disks and inconel combustor liners, ensuring dimensional accuracy for cooling channels and structural integrity.
Oil & Gas Exploration: Fabrication of deep-hole components for subsea pumps (stainless steel 15-5PH) and drill collars, resisting corrosion and high-pressure environments.
Power Generation: Drilling and boring steam turbine shafts (HSLA steel) and generator rotors, where hole straightness and surface finish are critical for balanced operation at 3,000 RPM.
Defense Industry: Production of gun barrels and missile guidance system tubes, requiring extreme precision (straightness ≤0.01mm/m) and surface roughness (Ra ≤0.4μm) for ballistic performance.
Q: What is the maximum depth-to-diameter ratio these machines can handle?
A: Standard models achieve 100x D, with specialized deep-hole versions capable of 200x D in stable setups, depending on workpiece material and rigidity.
Q: Can these machines perform both drilling and boring operations?
A: Yes, the spindle can accommodate drilling tools for hole creation and boring bars for diameter enlargement, with precision feed control for finishing operations (tolerance ±0.02mm).
Q: What maintenance is required for long-term accuracy?
A: Regularly calibrate the laser alignment system (monthly), replace coolant filters (every 200 hours), and lubricate linear guides (daily) to maintain positional accuracy and spindle performance.
Q: Do you offer machine customization for unique workpiece sizes?
A: Yes, we design custom machines for oversized workpieces (diameter >1,000mm, length >20 meters) with optional gantry-style structures and heavy-duty clamping systems.
