A deep hole drilling and boring machine is a specialized industrial tool engineered to create and refine deep internal holes with high depth-to-diameter ratios (often exceeding 10:1 up to 400:1) while maintaining tight straightness, concentricity, and surface finish tolerances.
Key Characteristics and Components
Rigid Bed & Structure: Built with heavy-duty dampening beds to minimize tool deflection and vibration over long lengths.
High-Pressure Coolant System: Delivers high-volume fluid to cool the cutting edge and flush out chips via specialized internal or external channels.
Workpiece & Tool Support: Uses steady rests, vibration dampers, and guide bushings to keep long drill tubes or boring bars aligned.
