Processing the contours, through grooves, and notches of elongated parts. We will examine the fixing and supporting methods as well as the processing sequence from the drawings.
At Hanshin Seiko Co., Ltd., you can consult us about wire cut electrical discharge machining for the contours, through grooves, notches, and irregular holes of elongated parts. We will confirm the overall length, width, and thickness of the part, the dimensions of the thin sections that remain after machining, and the positional relationship with reference surfaces and reference holes. We will consider the machining process according to the shape and required precision, including special outer contours and through grooves in the longitudinal direction. As the machining progresses, the parts that can be held and the remaining wall thickness change, so we will also take into account the shape during machining and consider the methods of fixation and support as well as the machining sequence. We will confirm not only the contour dimensions but also the straightness and flatness of the entire part and the specifications of the measurement conditions. Even for additional machining on a specific part, please provide the drawings of the entire part. For special contours, please contact us with the CAD data attached.

basic information
■Main processing method: Wire cut electrical discharge machining ■Processed shapes: Special outer contour, notches, longitudinal through grooves, irregular through holes ■Dimension verification: Overall length, width, thickness, remaining wall thickness after processing ■Reference verification: Reference surfaces, reference holes, processing positions, fixing/support positions ■Quality verification: Dimensional tolerances, straightness, flatness, inner corner radius, surface roughness *Applicable dimensions and precision will be judged individually based on material, shape, and holding conditions. *For shapes that end in a bottom groove or in the thickness direction, alternative processing methods will be considered. *Deformation may occur even with wire cutting.
Price information
We will provide a customized estimate based on the material, overall dimensions, processing shape, required precision, holding method, and quantity. If additional processing is required, please also inform us of the current processing status.
Delivery Time
※The processing details, storage methods, quantity, and condition of the supplied materials may vary. Please consult us with the planned supply date and your desired delivery date.
Applications/Examples of results
【Uses and Consultation Examples】 ■Special outer contour processing of elongated parts ■Through groove processing provided in the longitudinal direction ■Notching and irregular through hole processing at specified positions ■Contour processing that leaves thin sections ■Processing of parts with specified straightness and flatness ■Additional processing on a portion of existing parts Please also inform us of the measurement conditions for confirming accuracy, such as when the fixture is removed or when supported at specified positions.
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/
