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 (DHD) is a stress measurement technique used in engineering materials and components to measure locked-in and applied stresses. The process measures residual stresses at a microscopic level with penetration of over 750 millimeters (30 in), without destroying the original component.

Advances in engineering technology have given common CNC machining centres gun drilling ability up to a certain depth-diameter ratio. Roundness and surface finish are among considerations. Common applications of deep hole drilling and machining processes include

Multi-tasking is the “in” phrase in engineering circles these days. It makes eminent sense. Why use a variety of machines to fabricate a component if you don’t have to? Every time you have to break a machine down and re-set it, it results in down time, and down time is unproductive time. The longer that any piece of kit remains idle, the less efficient any company’s production process will be.

The Advantages of Multi-tasking

In addition to the actual down time of the machine, there’s also the physical act of moving components around the shop floor to be considered. It’s not only labour intensive. You also run the risk of losing or miscounting items within a batch, or of course misplacing the batch altogether. With a multi-tasking machine, (where all of the various operations are done on the same piece of kit), there’s far less down time. The risk of losing or misplacing items is completely eliminated.
