Narrow grooves and fine grooves shape carving electrical discharge machining | Deep grooves and bottomed grooves
We will consider additional processing for the bottomed grooves and high hardness materials from the drawings, where tools cannot fit and the depth cannot be reached.
At Hanshin Seiko Co., Ltd., we accept processing of narrow grooves, fine grooves, and deep grooves, primarily focusing on shape-cutting electrical discharge machining. You can consult us about grooves that are difficult for cutting tools to access, specified grooves with small inner corner radii, and additional processing for high-hardness materials after hardening. We will check not only the groove width but also the depth, length, bottom shape, and end shape. We will consider the production and retention of electrodes, interference with surrounding areas, electrode wear, and discharge of machining chips when determining the processing method. For through grooves, we select wire cutting, while for bottom grooves, we choose methods such as shape-cutting electrical discharge machining or machining, depending on the shape. We can also discuss integrated processing, including grinding, as needed. Please contact us with a cross-sectional diagram of the groove, material and hardness, required tolerances, surface roughness, and quantity. For additional processing on existing parts, we will also check the processing standards and the current work condition.

basic information
■Target shapes: Narrow grooves, fine grooves, deep grooves, bottomed grooves, grooves including small R ■Main processing method: Shape cutting electrical discharge machining ■Target materials: Conductive materials. High hardness materials and hardened materials can also be consulted ■Shape confirmation: Groove width, depth, length, bottom surface, end shape, step difference, corner R ■Accuracy confirmation: Groove position, tolerances of width and depth, surface roughness ■Multiple grooves: Check the spacing between grooves and the remaining thickness between grooves *Minimum groove width, maximum depth, and applicable accuracy will be determined individually based on material and electrode shape, etc. *It does not guarantee a complete inner corner R of zero.
Price information
We will provide a customized estimate based on the width, depth, length, material, required precision, electrode fabrication, and quantity. Please also provide a cross-sectional view that shows the shape of the bottom surface.
Delivery Time
※The processing content, electrode production, number of grooves, and quantity of parts may vary. Please consult us with the planned delivery date and your desired delivery date.
Applications/Examples of results
【Applications and Consultation Examples】 ■ Machining of narrow grooves where cutting tools cannot enter ■ Machining of fine grooves where tools cannot reach the required depth ■ Machining of stopped grooves that leave a bottom without penetrating ■ Adding grooves to parts after hardening ■ Machining of grooves with specified small inner corner radii ■ Machining of grooves with steps or special shapes on the bottom surface For additional processing on existing parts, we will provide guidance on the feasibility of machining after confirming the reference surfaces, reference holes, and the currently machined state, as well as the parts that can be held.
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/
