GFIS: Floating holder
GFIS holder has floating mechanism.Possible to attach to ER32 collet chuck.
Reaming: RM-BN6-16.000-H7SA IC908 (indexable reamer)
Workpiece clamping condition
Machine: Mitsui Seiki Kogyo
Tools for comparison
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.
Hole surface after reamer processing
GFIS holder has quite smooth surface.
Attach to collet chuck
You can use your own collet chuck.
Improve hole accuracy
In case not finished with intended hole diameter.
Improve surface damege
In case of poor surface after reaming.
Machining with internal coolant
Internal coolant is necessary.
