This device is used for automatic balancing measurement and milling weight removal of brake discs. The measurement and weight removal can be performed simultaneously at two workstations. The equipment adopts an electromechanical integrated structure, so this series of automatic balancing milling and weight removal machines has a compact and highly automated structure. In addition to loading and unloading the workpiece, the entire process of "workpiece clamping - balance detection - de repositioning - milling correction - retesting (with adjustable interval frequency)" is automatically completed by the operator, which improves the production efficiency of the balancing process and can meet the production cycle requirements and consistency of balancing accuracy for large quantities of parts.
