Deep Hole Drilling: Precision Engineering for Aerospace, Automotive & Defence

The Future of Precision Manufacturing: Exploring Deep Hole Drilling

Deep hole drilling is at the heart of some of the most critical engineering advancements. Think about the performance of a jet engine, the dependability of an airbag deployment system, or the precision of a guided missile. All of these systems across the aerospace, automotive, and defence industries rely on components produced with exceptional accuracy. Deep hole drilling (DHD) is the process that makes this possible, handling high aspect ratios and strict tolerances that are vital for high-performance applications.

What Is Deep Hole Drilling And How Does It Work?

Deep hole drilling is a machining process that can produce holes up to ten times deeper than the diameter of the hole and is suitable for a variety of metals, including the strongest of superalloys. Deep hole drilling services require special tools and setups to deliver high-pressure coolant, cleanly evacuate chips and reach the depth-to-diameter. Deep hole drilling, also known as gun drilling, is a highly-specialised machining operation that only a few engineering companies can perform, including PRV Engineering. Here is a closer look at some of the processes, applications and pros and cons.

Deep Hole Drilling As A Manufacturing Technology

Deep hole drilling (DHD) – or deep hole machining (DHM) – is a residual stress measurement technique often referred to as gun drilling. It’s a prominent method in engineering materials and components used across numerous sectors, including automotive and vehicle construction, aerospace and renewable energy. Deep hole drilling is also used in die and mould making and hydraulics or pneumatic components.

Today, there’s a growing demand to put gun drilling into a multi-tasking format, just as you would with common machining techniques such as milling, turning and gear-cutting on one platform. With deep hole machining being a multi-task platform you can create opportunities to offer an incredibly high-quality finished product.

Deep Hole Drilling And Multi-Tasking Machining

Deep hole drilling, often referred to as gun-drilling, is a highly-specialised machining operation that only a select few engineering companies can perform. This method is used when high-precision round bores are vital to the operation. It produces holes that can be controlled within very tight tolerances, giving much greater accuracy compared to conventional drilling methods.
