Non-penetrating square holes and stepped holes. We will consider the electrode and process based on the type of carbide material, depth, and inner corner radius.
This is a contract processing service from Hanshin Seiko. We will consider processing methods using shape-cutting discharge for square holes with a flat bottom and stepped irregular holes in cemented carbide. Since the information "cemented carbide" alone is not sufficient to determine the conditions, we will also check the material type, material code, pre-processing state, and whether surface treatment is applied. Cross-sectional views and CAD data that show not only the outline from above but also the hole depth and bottom shape are important. The image is an illustration to explain the processing content and is not a photo of individual production achievements.

basic information
【Material】Super hard alloy. Check conditions for each material type. 【Processing Method】Sinking electrical discharge machining. 【Shape】Consultation for bottomed square holes, polygonal holes, stepped irregular holes, etc. 【Conditions】Inner corner radius, depth, bottom surface, positional reference, tolerances, surface roughness. Consider the discharge gap and electrode wear. Shapes that are wider inside than at the entrance require consideration for electrode entry and exit, and are not assumed to be feasible. Depending on the usage conditions, it is also necessary to confirm the processing altered layer and finishing conditions.
Price information
We will provide a detailed estimate including the production of electrodes based on the type of superhard material, contour and cross-sectional shape, depth, finishing conditions, and quantity.
Delivery Time
※We will confirm the material type, drawings, quantity, pre-processing condition, and desired delivery date before providing guidance.
Applications/Examples of results
[Example of Use] Bottomed concave shapes or positioning shapes for mold parts and wear-resistant parts. This is a description of the application and does not indicate production results for all listed shapes. First, confirm whether it is a through hole or a hole that leaves a bottom surface, and then consider the feasibility of processing for each drawing.
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/
