GFIS ER32X70-ER32
Collet chuck holder with floating system
(Testing with ER32 collet chuck and GFIS holder)
HSK-A63 HYDRO 16X95
Iscar HYDRO Chuck
We got the same result: GFIS holder with misaligned 0.075mm from the center and HYDRO chuck without offset.
Expected machining is possible by floating holder even the machine is misaligned.
