60 metres per minute: This speed sets the pace for the drilling stations integrated into the IMA Klessmann GmbH rigs. They have to drill at high speed, even if the components are manufactured according to specific orders and have different drilling patterns. The IMA Klessmann "Drilling Technology" business unit has developed the flexible IMAGIC flex drilling system for this application profile. The individually controllable drilling spindles enable horizontal and vertical drilling as well as dowelling, and promise minimum set-up times even for complex drilling patterns - and at a remarkably high speed. The systems, which are planned specifically according to customer requirements, are equipped with up to 50 axes, which must be positioned and coordinated in seconds. In order to prepare the IMAGIC flex for this task, the designers had to "upgrade" the drive and control technology appropriately and decided to use the latest servo technology. The new one-cable technology combines the power and feedback system in the same servo cable. The single-cable technology saves material as well as costs and installation effort, since depending on the position of the control cabinet - which is specified by the customer - up to four kilometres of cables are laid. At the same time, however, this brought with it the challenge that a hybrid cable was required that could guarantee a long service life and dependability at the same time, given the high dynamics. Another complicating factor is the very small bend radii, because leading control technology companies had rejected the single-cable concept in the past. IMA took these concerns seriously, especially since the mobility of the hybrid cables was added as an extra factor.
