GFIS Floating Chuck for High Speed Cutting Reamers
ISCAR is introducing the GFIS ER32X70-ER32, a new floating chuck for high speed cutting reamers.
The GFIS ER32X70-ER32
floating chuck is designed to enable optimal reamer performance - especially ISCAR’s BAYOT-REAM
reamers that feature interchangeable reaming heads.
Floating chucks are used for high-precision hole making, to correct any misalignment between the reamer and hole centers. Precise alignment is essential for optimal performance and hole accuracy.
is an extension of the ST GFI floating chuck, which for many years has successfully served mainly hole making industry users of solid HSS and carbide reamers that run
at low cutting speeds.
The GFIS ER32X70-ER32 is unlike any other floating system in the market, with a unique technology that ensures the system remains completely rigid until it reaches a steady state of reaming.
This is achieved by a semi-clutch floating mechanism that only starts floating once the reamers penetrate into the bore and the cutting forces are applied.
This feature is especially important on horizontal machines where the reamer tends to wobble, which can damage the chuck and hole entry.
GFIS ER32X70-ER32 has an ER32 shank that can be attached to any standard tool holder with an ER32 connection.
No set-up time
No need for adjusting to μ micron runout accuracy
No need for expensive hydro chucks for each reamer
Suitable for all types of ER32 Collet Chucks
Built-in ER32 Collet Chuck
Featuring high precision and low runout, suitable for various standard toolholders with ER32 taper.
