Leave the necessary dental parts of the ready-made product and cut it out to the specified shape. Determine the position based on the center hole and round hole, and accommodate additional processing with specified angles.
At Hanshin Seiko, we accept consultations for cutting and additional processing using off-the-shelf sprockets. The case presented involves cutting out the necessary tooth section from a standard sprocket and shaping it to the specified form using wire-cut electrical discharge machining. The rotational position was determined based on the center hole and round hole, and the processing was aligned to the specified angle. In additional processing of off-the-shelf products, the positional relationship between existing holes or teeth and the newly processed contour is crucial. The center position is captured from the center hole, and the direction of processing is determined based on its relationship with the round hole. Emphasis is placed on establishing a reference before processing, confirming the relationship between the existing shape and the processing position. For inquiries such as "I want to cut out part of an off-the-shelf product" or "I want to specify an angle relative to the reference hole," please send us the product specifications and processing drawings. We will confirm the material, dimensions, processing range, angle, tolerances, quantity, and desired delivery date to provide guidance.

Applications/Examples of results
【Processing Results】 Cutting out the specified shape while leaving the necessary tooth parts from a standard sprocket. This is an example of processing based on the center hole and round hole to determine the position in the direction of rotation. 【Additional Processing Consultations】 - I want to cut out a part of a standard sprocket. - I want to change the outer shape while leaving the necessary tooth parts. - I want to specify the processing angle relative to the reference hole. - I want to align the positional relationship between the existing holes and the processed contour. *This is not the sale of standard sprockets, but a contract additional processing service for existing products.*
Company information
Hansei Seiko Co., Ltd. is a precision metal processing company founded in 1948, based in Kobe City, Hyogo Prefecture. We offer integrated processing services centered around wire cut electrical discharge machining, shape electrical discharge machining, and fine hole electrical discharge machining, as well as machining, polishing, finishing, and measurement. We welcome inquiries for precision parts, mold components, jigs, test pieces, and more, whether for single items, prototypes, or small lots. In addition to processing hardened steel, carbide, and stainless steel, we also handle contour machining of thick parts, key grooves, fine slits, and complex shapes. We confirm material, shape, required precision, and application, and consider processing conditions and processes. This reduces the burden of arranging multiple processing locations and supports part manufacturing. Based on the principle of "making according to the drawings," we conduct inspections and measurements in-house to confirm the finish before shipping. Based in Kobe and Hyogo, we accept processing inquiries and quotation requests from across the country. If you have parts you are struggling to process or drawings for which you would like to consider methods and processes, please feel free to consult with us. https://www.hansei.co.jp/
