Please consult us regarding the cutting, shaping, and V-notch processing of Charpy impact test specimens. We will take into consideration specified shapes such as a tip radius of 0.25mm and the processing surfaces.
At Hanshin Seiko, we accept wire-cut electrical discharge machining of Charpy impact test specimens based on provided drawings. We will consider the manufacturing method according to your desired processing range, including cutting from the material, contour machining, and V-notch processing. For specified shapes such as a V-notch with a tip radius of 0.25mm, we take into account the notch depth, angle, tip radius, and the contour connecting the slope to the tip radius. We combine wire diameter, discharge gap correction, feed, tension, and processing fluid conditions to perform finishing cuts according to your requirements. We confirm the sampling position of the test specimen, material direction, and the surface where the notch will be created, processing while inheriting the identification information of the supplied material. If necessary, we will also consider preparing reference surfaces through cutting or grinding. Along with the drawings, please provide information on material, heat treatment condition, applicable standards and versions, surface roughness, inspection requirements, quantity, and desired delivery date. We will check the scope of processing, finishing, and inspection and provide guidance accordingly.

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/
