[Production Example] Motor Core (φ110×0.2mm)

Motor core by wire cutting

This is a motor core (φ110×0.2mm). The material is 35A440, and it is primarily used as a component for power transmission devices. For this core, we processed it by sandwiching multiple stacked blank materials with thicker iron to reduce vibration during processing caused by the injection of cutting fluid. The processing steps were carried out in the order of "outer circumference rough machining → hole rough machining → outer circumference finishing → hole finishing." Additionally, for motor cores of this shape, having only one start hole on the outer circumference would cause the workpiece to move during processing, so we created two or more start holes for machining. Our company is capable of sourcing a wide range of materials, from general iron and SUS to amorphous products and special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. Therefore, we also propose cost reduction from the design stage based on past processing data. If you are facing challenges with the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.
