What is a Deep Hole?
A deep hole is defined by its depth-to-diameter ratio (D:d), and typically holes greater than 10:1 are considered deep holes.
Deep hole works into metal has a range of applications across several industries, with its origins tracing back to the need for straighter, more accurate military gun barrels, and expanding as other industries integrated deep hole processes to improve their own applications.
Deep hole processes work by using special tools and setups to deliver high pressure coolant, evacuate chips cleanly, and achieve depth-to-diameter holes into metal beyond what a common CNC machine can reach. This allows manufacturers to achieve their manufacturing tolerances and production requirements reliably, accurately, and efficiently.
Deep hole working is generally performed on dedicated deep hole machines which are manufactured and assembled to optimize the processes for straightness and efficiency.
Profimach produces under OEM highly capable BTA and gundrilling machines, with applications exceeding 400:1 D:d ratios.
