Deep Hole Drilling FAQ
What makes deep hole drilling different from conventional drilling?
Deep hole drilling requires specialized equipment and techniques to maintain precision over long distances. Unlike conventional drilling, it uses high-pressure coolant systems, specially designed tooling, and precise guiding mechanisms to achieve straightness and surface finish requirements. The length-to-diameter ratio in deep hole drilling typically exceeds 10:1, requiring entirely different approaches to chip evacuation and heat dissipation.
How do you ensure accuracy in deep hole drilling operations?
We employ multiple precision-enhancing techniques including vibration-damped tool holders, high-stiffness machine structures, and real-time monitoring systems. Our machines feature laser-guided alignment systems and automatic tool compensation to maintain straightness throughout the drilling process. Coolant pressure and flow are precisely controlled to ensure optimal chip removal and minimize tool deflection.
What materials are suitable for deep hole drilling?
Deep hole drilling can process virtually all machinable materials including various grades of steel (up to 65 HRC), stainless steels, titanium alloys, nickel-based superalloys, and non-ferrous metals. The key is selecting appropriate cutting parameters, tool geometries, and coolant formulations for each specific material. We provide material-specific machining recommendations with each of our deep hole drilling systems.
