A deep hole is defined by the depth-to-diameter ratio and every hole larger than a ratio of 10:1 is considered deep. There are lots of applications for deep hole drilling across many industries, with the origins tracing back to gun barrels. Deep hole drilling is used in different materials and can help achieve a tight diameter, straightness, and a perfect surface finish.
Tubular based components are used in tens of thousands of applications by manufacturers in a wide range of sectors. These components vary enormously in size, capacity and use, but the method by which each is made is broadly similar.
The precision engineering methods used to make industrial tubes and shafts include deep hole drilling, deep hole boring, gun drilling, CNC turning and CNC honing.
