NIKKEN's Mini-Mini Advanced Alpha is the latest generation of our Mini-Mini chuck. Recently completely redesigned the system, as with the Slim Chuck and Major Dream Holder, is based around an 8 degree collet system. The Mini-Mini differs is in its construction by adopting a collet which is extended and uses a precise ‘pilot’ location diameter with a threaded bore at the rear. Once loaded into the holder the collet engages with an internal drawbar which is actuated from the side using precision internal gears effectively pulling the collet backwards to clamp. This concept completely negates the requirement for an external clamping nut and allows Mini-Mini to be one of the most effective and compact collet systems on the market. The key advantage, and ultimate benefit of this design, is that because the external nut and it’s associated thread are eliminated the front nose diameter can be considerably more compact. This provides the customer excellent access and clearance for demanding and tight to hit areas around parts and components.
