Deep-Bore Drilling
With deep-bore drilling, bore-holes up to 120 mm deep, with diameters of 3-12 mm can be drilled on our Swiss-type lathes. Here, it is important to minimize deviation of the drill head center from the central axis, as the drill shaft's flexural rigidity can decrease, depending on its length.
The gun drills that are predominantly used are designed to guide themselves along the wall of the pre-drilled hole. For precision deep-bore drilling, one of the crucial factors is a high oil pressure of 120 bar throughout the drill, for removal of borings from the bore-hole.
We typically use deep-bore drilling for soap dispenser outlets, but to an increasing extent also in the medical domain, e.g. for bone screws.
