It is over 50 years since Nikken first developed the Multi-Lock Milling Chuck. Though much copied but never bettered we have again stayed ahead of the game and re-developed our technology to launch our very latest version of the 'Anniversary' type multi-lock milling chuck.
Our latest generation Multi-Lock has a completely re-designed internal taper and external nut mechanism. These extensive revisions also feature an all new roller retainer containing a multitude more bearings, at a much higher density, than the previous version.
The new multi-roller system far exceeds the original specification of 140% more needle rollers than any comparable chuck. Also, to allow for a more consistent and permanent gripping force when clamped the rollers are arranged differently in more rows than ever before. The new internal construction and design also provides a greater degree of dampening during any cut.
The original internal slots within the chuck bore are combined with a thickened body wall and improved taper design to ensure there is no distortion even when heavy milling. So our latest generation product provides extremely smooth milling without any vibration or chatter.
For precision milling we have always maintained that it is essential to clamp the tool at the chuck nose. The new Multi-Lock, as it always has, incorporates such a mechanism within its design. This has a direct beneficial effect on the resulting surface finish as well as extending the life of any tool. Our Multi-Lock milling chuck clamps perfectly even at a mere 3mm from the chuck's nose.
