Honing to Swiss perfection
Die Firma Fässler AG ist ein mittelständisches Schweizer Famili
enunternehmen, welches als Erfinder des Zahnradhonens gilt.
Als das Unternehmen im Jahre 1970 gegründet wurde, stand
das ehrgeizige Ziel des Firmengründers Albert Fässler, Zahnräder wirtschaftlicher herzustellen und die bis anhin erreichte
Zahnräderqualität zu verbessern.
Seither steht der Name Fässler für Qualität und Zuverlässigkeit.
Seit mehr als 40 Jahren produziert die Fässier AG
Werkzeugmaschinen in der Schweiz.
Durch das langjährige Know-how und innovative
Ideen hat sich die Firma als Marktführer für
Zahnradhonmaschinen etabliert. Angepasst an
die Kundenbedürfnisse liefert das Schweizer
Unternehmen schlüsselfertige wie auch kundenspezifische Lösungen von derWerkzeugmaschine
bis zum After-Sales Service.

ANALYSE
Das Honen von Aussen- und Innenverzahnungen wird weltweit von führenden Getriebeherstellern zur Hart-Feinbearbei
tung eingesetzt. Der Prozess bietet bei Klein- wie auch Grossserienproduktion überragende Qualität und hervorragende
Produktivitätsgewinne. Zahnradhonen ist bei vielzähligen
Anwendungen unerlässlich, um die geforderte Qualität, Laufruhe und Energieeffizienz zu erreichen. Im Vergleich zu anderen
Prozessen sind die lnvestitions- und Werkzeugkosten gering.

GEAR HON ING
MACHINE
Kl N EMATICS
The honing machine model used is based on
various factors such as component dimensions, gear
geometry and desired production numbers. The
Fässier HMX family provides flexible solutions for
honing ofa multitude ofexternal and internal gears,
crankshafts, cluster gears on shafts and many more.
With the use of a variety of automated part loading
solutions, honing is one ofthe most economical and
fastest hard gear finishing processes.
In a typical application, an internally toothed honing stone
makes rolling contact with the work piece and is combined
with an oscillating movement of the honing stone. Cutting
forces are also generated in the radial as weil as axial direc
tion via a crossed-axes angle between the honing stone and
the work piece. Cutting speeds vary across the tooth flank and
thereby result in a high surface finish and compressive stresses
to the surface structure, which is best known for good running
properties, noise reduction and durability.

THE PERFECT COMBINATION OF
TECHNOLOGY,TOOL AND MACHINE
The necessary tools for external honing are composed of a
ceramic bonded abrasive the honing stone and a diamond
coated master and dressing wheel.

MAXIMUM
EFFICI ENCY
The long intervals between dressing in honing inheritably result
in very bw tooling costs. Combined with bw cycle times, high
productivity at a bw investment is ach ieved.
MAXIMUM QUALITY
AND PROCESS RELIABILITY
Highly accurate Profile and Lead forms, as weil as pitch and run out
results, can be improved by 2 to 4 DIN classes depending on the
work piece. The high repeatability of Honing provides a highest
degree of process reliability.
MAXIMUM TRANSMISSION
SMOOTH N ESS
The honing process provides a fine finish with an also highly
diffused surface structure on the tooth surface. This is characterized
by many small pockets, which contain the lubrication oils and provide
additional dampening and bw noise emission. Furthermore, the
diffused machining marks provide an excellent surface quality
resulting in a smooth rolling contact of mating gear teeth.
MAXIMUM
DURABILITY
By process-related introduction of compressive residual surface
stresses, the wear resistance and durability ofthe tooth surfaces are
significantly increased.
NO THERMAL
STRESS
The bw cutting speeds of the honing process have no nega
tive thermal impact and no structural changes during processing.
Consequently, the risk of surface burns and annealing resulting in
possible gearbox failure is virtually eliminated.
FREEDOM IN
GEAR DESIGN
Lead modifications such as bias, anti-twist or tapers can be easily
produced when manufacturing the dressing tools. These correc
tions are reliably transmitted via the dressing gear and the honing
stone to the work piece.
