Considering the advanced industries using gun drilling, it’s evident that production of certain parts requires a reliable, time-efficient and accurate process. Here’s what it all entails and why it’s so important when choosing the right engineering company.
The continued advances in technology have allowed common CNC machining centres equipped with high-pressure through-spindle coolant to be capable of deep hole drilling up to a certain depth-to-diameter ratio. Of course, other considerations include roundness and surface finish as well.
What Is Gun Drilling?
In laymen’s terms, gun drilling is a specialist machining operation that creates holes deeper than ten times the hole’s diameter. These holes can be controlled within very tight tolerances providing exceptional accuracy compared to conventional drilling methods. It is highly advantageous when a project requires high-precision round bores for high-performance end products.
Some of the more common applications for deep hole drilling is in oil and gas exploration equipment, armaments, aerospace equipment and engines. In each of these industries, the quality of the hole needs exact precision with extreme reliability. Examples of where gun drilling plays a major role include the following:
- landing gear
- steering columns
- hydraulic rams
- heated platens
- plate rolls
- injection mould tools
The Versatility Of Deep Hole Drilling
Gun drilling has been used for quite some time and it’s been perfected over the last few decades. It can produce highly flexible, accurate and reliable results and suitable for a number of materials, including steel, aluminium, titanium and alloys. Some projects may require custom features for the holes like threading or grooves.
Furthermore, gun drilling can also be used to increase streamlining while reducing the weight of engine parts. Of course, this is greatly beneficial in the aerospace sector to help build more efficient aircraft. Not only that, gun drilling plays a crucial part in oil and gas exploration and extraction. As you can imagine, this industry needs durable, high-capacity tubing that meets the most stringent machining requirements.
Deep hole drilling is a highly specialised field and not many engineering companies have the necessary knowledge, experience or machinery. Here’s what PRV Engineering can do for you.
