Ultra-hard deep groove processing | Investigating bottomed fine grooves using shape electric discharge machining.
Check not only the width of the groove but also the depth, length, and bottom surface. Consider the electrode and the discharge of machining chips as well.
This is a contract processing service by Hanshin Seiko. When you want to create fine grooves or deep grooves with a bottom left in cemented carbide, we consider using a method of shape cutting discharge. Even with the same groove width, the required electrode and processing conditions change with depth. We take into account the retention of long electrodes, discharge gap, electrode wear, and the discharge of machining chips, and separate rough processing and finishing processing as needed. Please let us know at the beginning whether you need a through slit or a groove with a bottom left.
Inquire About This Product
basic information
【Material】Super hard alloy. Check material type, manufacturer, and material code. 【Processing Method】Shape engraving electrical discharge machining. 【Shape Conditions】Groove width, depth, length, bottom step, corner radius, positional reference, tolerance, surface roughness. In deep grooves, the discharge debris removal and electrode wear can affect the shape of the bottom and sides. There is also a possibility of processing alteration layers and fine cracks, so confirm finishing and surface quality conditions according to the usage environment.
Price information
We will confirm the material type, groove cross-section, length, depth, bottom surface, finishing conditions, and quantity, and provide an individual estimate including electrode fabrication.
Delivery Time
※We will confirm the drawings, CAD data, material conditions, required quantities, and desired delivery dates, and provide you with guidance.
Applications/Examples of results
[Usage and Shape Examples] Bottom grooves of mold components, narrow recesses of wear-resistant parts, fine grooves for guiding materials, and concave shapes with multiple depths. This is a general example of inquiries and does not represent all of our manufacturing achievements. We will confirm the feasibility of processing based on drawings and material information.
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/
