Product catalog summary
Description
The document describes a soft-bearing vertical balancing machine designed for measuring and correcting the unbalance of disc-shaped rotors. It can perform measuring, machining, and auditing in one to three stations based on cycle time requirements. The workpiece is clamped using a high precision holder for measuring and a swivelling chuck for unbalance correction. Swarf is extracted via an exhaust hood, and a measuring computer handles sequencing, unbalance measurement, and compensation calculation.
Applications
The machine is used for balancing automotive brake discs and drums. It can be configured as a manual single machine or integrated into a production line. Loading options include manual, interlinking with lift swivel transport, robot, or gantry loader. Unbalance correction is performed radially on the external disc diameter with a side-milling cutter, and workpieces can be fed in batch or mixed operation.
Advantages
The machine features a space-saving, compact modular design and offers fully automatic balancing with unbalance correction by milling. It includes a measuring computer with touch screen operation and can be integrated into production lines. The handling system is designed for a large tool range with reduced changeover time. An optional automatic calibration system with remount check is available.
Technical Data
The BVW11 model is available in three configurations (F1, F2, F3) with the following specifications: rotor weight up to 25 kg, maximum outer diameter of 410 mm, machine dimensions of 2000 x 3700 x 2000 mm, balancing speed of 600-800 rpm, measuring uncertainty of less than 10 gmm, cutter diameter of 125 mm, cycle time ranging from 12 to 30 seconds, cutter drive power of 7.5 to 14 kW, and power consumption of 27 to 36 kVA. The number of stations varies from 1 to 3.
Options
The machine offers various options including sleeve, lamella, or segmented mandrel holders for unbalance measuring, hydraulic or pneumatic axial clamping chuck or radial chuck for unbalance compensation, hole scanning for rotor type detection, displacement measuring system in the gripper, cut detection, cutter set for up to 3 cutters, vertical NC cutter head positioning, test rotor with calibration weight, automatic calibration system with remount check, report printer, and additional software for statistics and production checking.
Scope of Supply
The machine comes with a rigid housing, measuring unit with workpiece holder, compensation unit with swivelling chuck, milling unit with NC feed, swarf extraction unit with exhaust hood, protection device class B per ISO 7475 with access doors, and a control cabinet with automatic control and measuring computer.
