Smart vacuum optimisation for
CNC nesting machines
By Ralf Sundmaeker
Having worked in the woodworking industry since 1985 and lived in South East Asia for over 25 years, Ralf Sundmaeker is currently based in Bangkok and is responsible for the Machinery business unit at Steinert Co Ltd.
The state-of-the-art vacuum pumps enable high precision CNC machining with maximum grip of the workpieces. Any of the eight zones can be controlled independently from the others and are controlled according to the spindle position. The worktable area and the vacuum power can easily be optimised during machining according to the workpiece, spindle position and board size.
During the CNC cutting operation, the first pump always secures the proper vacuum for the area at which the spindle motor is actively working. The second pump distributes the vacuum power to the remaining areas to keep the boards firmly fixed on the CNC table. The divided and flexible vacuum distribution produces the strongest holding power where it is needed most – exactly where the cutting and routing takes place.
According to the spindle position, the system opens or closes the vacuum zones and by doing so reaches a vacuum power that is ten times stronger than a standard system. Vacuum reservoirs mounted under the CNC table hold additional air to easily transfer that to the working table once needed.
Steinert includes the Vacuboost system for the following AES CNC nesting machines: Raptor Ultra, Extreme Ultra and Super Nova models. All mentioned types are laid out for fastest operational speeds, with the Vacuboost holding even the smallest workpiece for perfect cutting results.
