| To reduce
unsprung vehicle mass, a lighter wheel with good stiffness, is the aim
in the case of steel wheels too. At the same time, a lower material content
generates cost savings. |
 |
| Wheel centre
discs are economically cold formed in one hit on flow formers in the ST
and AFM series. The effects of blank thickness and mechanical strength
variations within a batch of material are eliminated by the use of thickness
gauging and hardness testing systems. Both units interpolate with the
CNC to select the appropriate programme. |

| Until
some years ago, tapered bead seat truck wheel rims were mainly produced
from rolled sections. Today it is possible to form such rims from
flat strip in just three steps. |
|
 |
| Special techniques
and machines have been developed for the production of tapered bead seat
rims of constant thickness e.g. for industrial applications and fork lift
trucks etc. as well as for drop centre and wide bed rims, enabling such
rims to be produced economically in relatively few steps. |
 |
| Machines from
the AFM 600 series are employed for the production of tapered bead seat
rims and for drop centre and wide bed rims, the TF series. |
