Anniversary Multi-Lock Milling Chuck - Standard
It has been over 40 years since Nikken developed the multi-lock milling chuck. Our development team have developed the latest generation universal chuck which we refer to as a Nikken 'Anniversary Type' Multi-Lock Milling Chuck.
One key feature of the Multi-Lock is the -90°C 'Sub-Zero' ultra-low temperature treatment that the holder is subjected to after carburizing.
This treatment removes residual austenite to prevent deformation during many years use.
Features:
 | The Anniversary Multi-Lock Milling Chuck incorporates our exclusive multi-roller system incorporating 140% more needle rollers and therefore bearing surface area than imitations. The retainer is NOT made of phosphor bronze but rather a special steel which will never break |
Clamping at the nose is a key condition for precise milling. Surface finish and tool life are decided on clamping at the nose, rigidity and run-our accuracy. Only Nikken's mechanism performs true clamping at the nose. This makes the Anniversary Type Multi-Lock Milling Chuck ideal for heavy milling to fine finishing. |  |
 | With the Nikken Anniversary Multi-Lock Milling Chuck it is possible to obtain a run-out accuracy of 5µm (T.I.R) at a position of 100mm from the nose (3 x dia. on C32 size). The Multi-Lock holds the cutting tool shank by deforming the cylindrical part of the body with pressure from the needle roller bearings - this deformation is parallel and consistent for the entire length of the chuck bore. |
