Punches and die are key components in motor core molds, facilitating the precise shaping and forming of laminations. They are made from tungsten carbide or high-quality steels and feature customized designs to meet the specific requirements of the motor core.
The punch and die need precision machining to achieve the final dimensions and surface finish. This may involve processes such as grinding, EDM (Electrical Discharge Machining), or wire cutting to create intricate features and precise contours on the parts.Quality control measures are essential to ensure the dimensional accuracy and functionality of the components. This includes inspection and measurement techniques such as coordinate measuring machines (CMM) or optical measurement systems, as well as the use of precision gauges and inspection tools.
