I. Introduction 

A deep hole boring machine is a metal-cutting machine tool, designed to produce very deep, precision holes into virtually any metal. Deep hole drilling machines enable the performance of specific tools such as BTA and gundrills, to optimize the deep hole drilling process for manufacturers. Machines are engineered to integrate the technology used by these tools, and optimize all aspects of the process, to drill deep holes with accuracy, reliability, and efficiency.

Deep hole boring machines are ideal for a variety of sizes of deep holes and production levels, and are necessary for holes that are approximately 20:1 depth-to-diameter or greater in ratio. Dedicated deep hole drilling machines provide the tooling support, coolant delivery, and process feedback that allow manufacturers to achieve their deep hole drilling goals. These features optimize the process and prioritize deep hole drilling methods, by reducing cycle time, stabilizing tooling, evacuate chips, and preventing tool breakage and process failures, when compared to CNC machining centers.
