Stop six-sided hole shape engraving discharge machining | High hardness materials, bottomed holes
For hexagonal holes that cannot be penetrated. You can check the dimensions of opposite sides, depth, inner corner radius, and orientation, and we can also discuss additional processing after hardening.
At Hanshin Seiko Co., Ltd., we can discuss the processing of stop hexagonal holes with a remaining bottom, primarily focusing on shape-cutting electrical discharge machining. We consider machining hexagonal holes in shapes where the inner corner curvature interferes with the counterpart parts, as well as additional processing of hexagonal holes in high-hardness materials and parts after hardening. We manufacture electrodes tailored to the hexagonal shape, taking into account the discharge gap and electrode wear. We verify not only the dimensions of the opposite sides but also the required insertion depth, inner corner radius, bottom surface shape, orientation of the hexagon, and the positional relationship with reference surfaces and other holes. Please feel free to consult us about integrated processing that combines wire cutting, machining, and grinding according to the shape. For quotations, please provide a top view and cross-sectional view, along with material, hardness, tolerances, and quantities. For additional processing on existing parts, we will check the current processing state and standards to inform you of the feasibility.

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/
