NIKKEN’s Zero-Fit Tool Holders align Precision and Efficiency.
Designed for increased precision and accuracy, NIKKEN’s Zero-Fit Solutions, guarantee sub-5µm run-out accuracy, even under demanding conditions where such precision was once considered unrealistic.
At extended lengths, achieving fine tolerances can become a serious challenge. However, NIKKEN’s Zero-Fit tool holders feature a uniquely designed adjustment system that is integrated seamlessly into the Multi-Lock Milling Chuck (CZF) and Slim Chuck 8-degree Collet Chuck (SZF). Both of these advanced tool holders are equipped with a highly precise adjustment ring featuring an internal cam system, which allows machinists to adjust tool rotation error, by up to 50 microns on diameter, with unparalleled accuracy.
How Zero-Fit Technology Works
By utilizing our unique adjustment ring the run-out can be physically tuned, either on a tool presetter or directly within the machine spindle, simply and accurately. This design not only offers an straightforward adjustment solution but also ensures that tool life and component finish quality are optimized.
The Zero-Fit technology is incredibly user-friendly: an operator can use a simple wrench to adjust the internal cam, which then “intensifies” or minimizes the run-out error (Zero-Fit is also available with a triple cam option to provide additional fine tuning). This adjustment process enables more efficient setups whilst providing lasting improvements in accuracy, minimized downtime due to tool wear and elimination of poor surface finishes.
High-Performance Applications in Motorsport
In the motorsport industry, where every component must meet exceptionally high standards of precision, NIKKEN’s Zero-Fit technology has quickly become a game-changer. Motorsport teams demand parts with tight tolerances to ensure top performance under intense conditions, where even minor inaccuracies can impact vehicle speed, handling, and safety.
With Zero-Fit’s exacting control, engineers can now machine critical components such as engine parts, drive systems, and aerodynamic fittings with unparalleled accuracy. The solutions not only ensure optimal performance but also reduce the chance of operator error, provide an ability to hit tolerances first time every time whilst ultimately allowing the potential for reduced consumable costs related to premature tool wear! All key factors in motorsport manufacturing where speed and efficiency are paramount.
For motorsport manufacturers and precision engineers alike, NIKKEN’s Zero-Fit offers a vital tool for consistently achieving the highest standards in component quality.
