On average, the spindle run-out accuracy on a CNC machine tends to decrease after 2-3 years of continuous use by an average of 0.001mm~0.004mm@100mm. The implementation of a ZERO FIT tool holder allows adjusting the spindle run-out offset, improving the run-out by 0.001mm~0.002mm@100mm, allowing a rapid improvement in the finish and quality of the work surface and extending the useful life of the cutting element. Simple, fast and safe with a wide variety of adjustment ranges.

The "Multi-Cam" fine adjustment allows avoiding variations between the setting on the machine vs the setting on the preseter through an adjustment of up to 3 points * "Multi Cam" type (depending on the model); 2 points 'Fine Adjust Cam' and 1 point 'Master Cam'.

* Note: Not all ZERO FITs are 'Multi Cam' type.
