Today, the Fässler gear-honing process with the HMX-400 is the most economical way for hard
finishing gears in mass production for the car, truck, motorcycle and aerospace industries.
Recently, the gear-honing process has become popular in the whole gear industry owing to
its technical and economic advantages.
The HMX-400 Gear-Honing Machines are exclusively intended for the green or hard finishing
of spur and helical gears, shaft type pinions, cluster gears and internal gears.
The 9-axis machine with the Siemens SINUMERIK 840D control system is particularly
distinguished by its compact design, outstanding productivity, and efficiency and
versatility, which allows for conventional double-flank honing, synchronous single- or
double-flank honing, as well as internal and combi honing. Longitudinal crowning and tapering
(conical honing) of the tooth flanks are also possible.

Comparison of Fässler's noise power spectrum vs. grinding
Decibel measurements have demonstrated that with a frequency of
3000 Hz, for instance, a noise reduction from 90 dBA to 55 dBA can be
achieved.

Axis concept – compact and rigid
|
A |
Swivels the honing stone
to the axis-crossing angle. |
| B1 |
Swivels the honing-stone
head (the pedestal on the
cross slide) for
longitudinal crowning and
tapering (conical honing). |
| B2 |
Swivels the turntable of
the headstock, i.e. the work
spindles, to honing or
loading/unloading position. |
| C1 |
Honing-stone drive:
positions and rotates the
honing stone. Positions and
rotates internal gears |
| C2/C3 |
Two work spindles
sitting on the turntable of
the headstock. They position
and synchronize the
workpiece or dressing tool
with the honing stone (C1
axis). |
| X |
Cross slide for the
radial movement (infeed) of
the honing stone towards the
workpiece or dressing tool. |
| Z1 |
Longitudinal slide for
the axial movement of the
honing stone (oscillation
movement). |
| Z2 |
Moves the headstock that
carries the 2 work spindles
to honing or
loading/unloading position. |
| Tailstock |
Supports the clamping
mandrel or shaft-type part
with rotating centre.
Normally, no axial movement
of the spring-loaded live
centre takes place. |
