Top Use Cases
Aircraft Components (Landing Gear & Actuators): Deep hole drilling is critical for aerospace parts like landing gear struts, actuator cylinders, and piston rods, which require extremely straight, long bores in high-strength alloys. This ensures precise fitment, strength under heavy loads, and smooth hydraulic operation. Aerospace standards demand micron-level accuracy, making advanced deep hole drilling systems indispensable.
Heat Exchanger Tube Sheets: Power plants and petrochemical facilities use tube sheets with hundreds or thousands of holes to hold heat exchanger tubes. Deep hole drilling machines create these parallel holes with perfect alignment, ensuring efficient heat transfer and leak prevention. CNC-controlled BTA drilling handles the job quickly, maintaining both hole accuracy and productivity.
Fuel Injector Bodies: Automotive and industrial engines rely on fuel injectors with very small, highly precise holes for accurate fuel spray patterns. Deep hole drilling—often via multi-spindle gundrilling—produces these holes with perfect roundness and surface finish, ensuring optimal combustion efficiency and lower emissions. Even minor deviations can impact engine performance significantly.
Hydraulic Cylinder Bores: Hydraulic cylinders in construction, mining, and industrial machinery need smooth, straight bores for proper sealing and piston movement. Deep hole drilling is followed by skiving and burnishing to achieve mirror-like finishes, reducing wear, improving efficiency, and extending service life. The process supports large diameters and long cylinder lengths.
Automotive Engine & Transmission Parts: Engine blocks, crankshafts, and transmission shafts often require long, precise oil and cooling channels. Deep hole drilling enables lighter, more compact parts by allowing thinner walls without sacrificing strength. This boosts fuel efficiency and supports modern vehicle design goals. Automation ensures these components meet strict quality and production volume targets.
Oilfield Exploration Equipment: Drill collars, downhole motors, and other oilfield components must withstand extreme pressure while maintaining structural integrity. Deep hole drilling allows precise bore placement and wall thickness control, critical for safety and performance. Specialized BTA and trepanning methods handle very large diameters and lengths used in offshore and onshore drilling rigs.
