One speaks of deep hole drilling from a diameter-length ratio of 12xD – the challenge with this kind of machining is that the drilling depths are considerably greater than the diameter. Drills up to 40xD are commercially available. There are various processes that are used for deep hole drilling. Spiralised solid carbide deep-hole drills are often the most economical option, as they can be used on all machines without any problems – provided the machine has sufficient coolant pressure.
As it is so often the case in production, the shape and position tolerances are particularly in focus. Moreover, the required diameter and surface tolerances must be observed and, finally, the optimal evacuation of the chips plays an important role in achieving optimal results.
To ensure high process reliability in deep hole drilling, preparation is important. Above all, ideal chip transport prevents damage to the tool or workpiece. In this whitepaper, we highlight the various deep hole drilling processes and show you how process-reliable drilling with solid carbide tools can succeed. You will also learn:
But that’s not all: Are you also interested in the topics “More performance in threading“, “Trochoidal milling: reducing costs, optimising processes” and “Machine Deburring“? We have compiled the most important information on these two disciplines for you in our white papers so that you are optimally prepared.
