Hofmann’s vertical hard-bearing balancing machines are used to precisely balance a variety of sizes and types of rotors which do not have their own bearing journals. In these type of applications, rotors are mounted to a vertical precision spindle using a suitable tooling adapter.
Vertical hard-bearing balancing machines from HOFMANN are used to balance mostly disc-shaped rotors without their own bearing journals, such as impellers from fans, compressors and pumps, coupling and transmission parts or pulleys. The core of a vertical hard-bearing balancing machine is a precision vertical spindle. Rotor mounts or adaptors are attached to the spindle’s interfacing flange. The rotor mounts clamp the rotor securely during balancing.
Hofmann’s vertical hard-bearing balancing machines are characterized by their exceptional availability. Their permanent calibration enables simple machine operation. The special Hofmann force measuring principle provides high measuring accuracy.
The balancing process can be improved by adding expansion options like unbalance correction systems. Flexible concepts for protective equipment improve machine safety.
Hofmann’s V-1 vertical, hard-bearing balancing machine is used for high-precision balancing of very small disk-shaped rotors up to a max. weight of 250 g (single plane) or 1 kg (dual plane) – like small fan impellers. The V-1 can be upgraded to a fully automatic balancing solution.
Type V-10 to V-300
Hofmann’s type V-10 through V-300 vertical, hard-bearing balancing machines are used for high-precision balancing of various small to large disk-shaped rotors without own journals and with a max. weight up to 1,000 kg. These machines can be upgraded to semi- or fully automatic balancing solutions using available options.
