Balancing Machines for Automotive Wheels
  • Modular machine design, optimally adapted to the job location
  • Semi or fully automatic sequence, flexible application through optional mixed-mode operation, short cycle times
  • Unbalance correction independent of the correction weight form; knock-on, clipmounted or self-adhesive are possible

Sequence of operations

  • Feed the wheel into the measuring station, center by the outside diameter, lower the wheel onto the balancing unit and clamp.
  • Measuring run to determine the unbalance amounts and angles, index the wheel and mark the correction angles.
  • Unclamp, lift and advance the wheel to the correction station.
  • Depending on the correction method in the correction station(s), knock-on, self-adhesive, clip-on weights or clamps can be attached manually or automatically. Sometimes the wheel is rotated to facilitate correction in the lower plane.
  • Move the wheel out of the machine and transfer it to the following station.

Range of application

Measurement and correction of unbalance in two planes in automotive wheel and tire sets. Processing of steel and/or light metal alloy rims of various dimensions and tire mounting. Unbalance correction by classified lead weights with integrated or separate clip or graded self-adhesive weights. Use in production environment in mixed operation. With the appropriate conveying system, the machine can be linked with other lines: valve insertion, tire-mounting, inflation and matching, tire stabilization, additional residual unbalance checking, final assembly.


Machine design for modular, building-block approach. Number of stations dependent on the function and required production rate.

Expandable from a manual, single-station machine to a transfer machine with automatic operating sequence. Loading and unloading either by operator or automatically. Simple handling, easy change over and fast faultfinding through modular concept.

Measured data processing by microprocessor based measuring unit CAB 850 with software package for calculating the optimum correction, statistics, self-test, etc.

Integrated unbalance correction change over from manual knock-on to automatic adhesion of correction weights.
