For small parts that are difficult to secure. We will consider the holding methods and jigs for irregular holes, fine grooves, and complex contours.
At Hanshin Seiko Co., Ltd., we can discuss wire cut electrical discharge machining for small parts with irregular holes, fine grooves, and complex contours. We will consider processing methods according to the drawings for square holes, through holes with special contours, narrow slits, notches, and asymmetrical outer shapes. Since small parts have limited areas for fixation, we will confirm the reference surfaces, reference holes, machining positions, holding points, and the remaining wall thickness after machining. We will also take into account the state during processing and consider jigs, fixation and support methods, and the order of machining. For fine grooves and small radii, we will check the processing conditions based on wire diameter, discharge gap, plate thickness, and required tolerances. For closed irregular holes, we will also consider the position and preparation method of the starting hole. If you have cases such as "the machining position is close to the edge" or "I want to leave a thin part," please consult us with drawings or CAD data that indicate the dimensions.

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/
