FEATURES

Compensates for synchronous error
 
It compensates for synchronous error not only axially, but also radially.
Infinitesimal radial error caused by machining can be corrected by the original mechanism.



Structure
 
Maintenance is not needed by using durable O-ring.
Since through-the-tool coolant and also along-side-th cutter coolant can be applicable, standard tap can be usable as well.

Maximum coolant pressure of
    SYFN : 7Mpa is applicable.
    SYFS : 5Mpa is applicable.


Tap holder for small diameter
 
Tap holder for small diameter doesn't clamp tap by collet, but clamps tap directly,
and this makes it possible to avoid breakage of M1, M1.6 and M2, too.

Machining Performance
 
Test cut with synchro tap holder and conventional collet chuck in the same program
The difference when resin material was tapped.
 
Left : Tapping with SYFN synchro tap holders leads to more accurate thread, reducing load on tap, and clear surface.
Right : Tapping with traditional collet chuck leads to rough thread and dim surface.
 
With the Synchro Tap infinitesimal float is used, increasing the degree of transparency, thereby illustrating the accurancy of threads are improved.
The difference at the time of the small diameter tapping
