BT tool holder MDSK

DINMorse tapercollet

Since the early days, originally to accommodate automatic work holding for the CNC Rotary Tables used on our production lines (with our ‘New Century’ Arbor), Nikken have always strived to provide solutions to counter the effects of vibration for both the workpiece and tool holding. Vibration is unfortunately experienced during the majority of machining processes. Should it become excessive then workpiece accuracy, surface finish and tool life can and is ultimately be compromised. The design and build of many Nikken tool solutions in fact do provide anti-vibration and dampening characteristics as standard. The Multi-Lock (with its internal guide cage and rollers) and indeed all our collet based systems can effectively reduce, to a degree, some of these potential issues – after all the itself collet could actually be considered as a hardened spring! NIKKEN's Major Dream is different. Its internals and construction are focussed solely to reduce and ultimately eliminate in-process vibration. Within the MDSK assembly is a pre-loaded split taper cone which, during manufacture, is forced forwards into a recess within the front body containing disk type springs. This means that the entire assembly is under pre-load the result of which being that cone and springs can effectively absorb any vibration from the cutting edge as it is transmitted up through the tool holder. The key benefits to in-process dampening are that the machine spindle is protected along with both the life of the cutting tool and workpiece surface finish being drastically improved.
