Shape engraving discharge machining after quenching | Additional processing and modification processing
Added deep grooves, small radii, and bottom-contact shapes to the heat-treated parts. Please consult us about shape-engraving electrical discharge machining before remaking.
At Hanshin Seiko Co., Ltd., we accept additional processing and modification of molds and precision parts after heat treatment. We will consider processing methods for high-hardness materials, focusing on shape-cutting electrical discharge machining, including deep grooves, small radii, and bottomed grooves and pockets, which are difficult for cutting tools to reach. We can accommodate design changes after heat treatment, finishing of rough-processed concave shapes, and processing of corners left from cutting. We will check the positional relationship with existing holes, outer shapes, and reference surfaces, as well as the remaining machining allowance and the parts that can be held, and guide you through the processes suited to the current work state. You can also consult us about integrated processing that combines wire cutting, machining, and grinding according to the shape. Please contact us with completed drawings, current processing conditions, and materials indicating additional or modified areas.

basic information
■Target: Conductive hardened materials, high hardness molds, precision parts ■Main processing method: Sinker EDM (Electrical Discharge Machining) ■Processing shapes: Deep grooves, fine grooves, small radii, bottomed concave shapes, pockets ■Processing content: Shape correction through additional processing and removal processing, finishing after rough machining ■Verification items: Material, hardness, heat treatment condition, depth, corner radius, processing standards, tolerances, surface roughness, remaining machining allowance *The feasibility of processing will also be confirmed considering the electrode entry direction, interference, and holding conditions. *Sinker EDM is a process that removes material. It is not possible to restore areas that have been excessively machined.
Price information
We will provide a customized estimate based on material, hardness, processing shape, required precision, electrode production, and quantity. Please provide materials that show the completed design and the current processing status.
Delivery Time
※The processing details, electrode production, quantity, and condition of the work will vary. Please let us know the scheduled delivery date and your desired delivery date.
Applications/Examples of results
【Uses and Consultation Examples】 ■ Additional processing due to design changes after heat treatment ■ Deep groove and bottom pocket machining on hardened molds ■ Finishing of rough-processed concave shapes ■ Processing of remaining inner corner areas from cutting ■ Addition of grooves to match existing holes and reference surfaces ■ Processing to remove or modify a part of the mold according to the drawing If there are drawings before and after the changes, please provide them as well. If there are specifications for the quality of the processing surface or the finishing of subsequent processes, we will confirm them in advance.
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/
