Higher Precision From the Start - The Deep Hole Drilling Process
Deep hole drilling is the process frequently used for initial hole generation in large-scale industrial parts. When combined with Sunnen’s industry-leading bore finishing operations, deep hole drilling delivers exemplary levels of precision and efficiency to a wide variety of manufacturing applications.
How Deep Hole Drilling Works
The deep hole drilling process was first developed in response to a growing demand for straight, accurate gun barrels. The process is now commonly used for machining any hole with a large diameter-to-depth ratio. Although many of the basic principles of drilling still apply, deep hole drilling employs various machine set-ups. The machines use ultra-high pressures to cut and remove chips evenly without damaging the workpiece.
The deep hole drilling processes are designed to:
Achieve tight diameter control and bore straightness
Allow easy setup and operation
Accept a wide variety of workpieces
Reduce changeover time and increase part production
