5.5.5 - Automatic minimization of static unbalance ►
Balancing of steel or light alloy rims with application of clip-on weights on the rim edges
The STATIC mode is necessary for motorcycle wheels or when it is not possible to
place the counterweights on both sides of the rim.
Balancing of light alloy rims with application of adhesive weights on the rim shoulders.
Combined balancing: adhesive weight on the outside, clip-on weight
inside.
Combined balancing: clip-on weight outside and adhesive weight inside.
Balancing of alloy rims with hidden application of the adhesive weight on the outside.
Combined balancing: clip-on weight inside and adhesive hiddenweight outside
(Mercedes).
This program is designed to improve the quality
of balancing without any mental effort or loss
of time by the operator. In fact by using the
normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two
counterweights which a conventional wheel
balancer rounds to the nearest value, there
could be a residual static unbalance of up to
4 g. The damage of such approximation is
emphasized by the fact that static unbalance is
cause of most of disturbances on the vehicle.
This new function, resident in the machine,
automatically indicates the optimum entity of the
weights to be applied by approximating them in
an “intelligent” way according to their position in
order to minimize residual static unbalance.
