Higher Precision From the Start - The Deep Hole Drilling Process

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
