Nazdar,

Vedel by mi niekto poradit, ako je to s pouzitim HSK A alebo C upinacov s vretenom, ktory ma automaticku vymenu (HSK F)? Kuzel by mal sediet, skor vidim problem v tom, ze forma F nema tie unasace, kym A,C maju.

Napisal na www.hskworld.com, odpisali mi toto, snad sa niekomu zide toto info:

It can be done, but caution have to be used.
Size of HSK shanks is defined by diameter of the flange.
A and C will always have larger taper than F for the same flange diameter.
So, depending on how big is ground flange on spindle you can conclude in it will fit.

Second consideration is tolerance for taper.
F style is done slightly larger (a few microns) than A and C to have more interference with spindle taper and as a result tighter grip.
It does not have drive keys, so torque is transmitted by friction.
A and C transmit torque by drive keys.

Last thing to consider is speed of rotation.
F style is symmetric and balance by design.
A and C are not, so they have to be balanced additionally.
