We will organize the entrance and exit positions and fixing methods, and examine the small diameter holes in the diagonal direction in the drawings.
This is a contract processing service from Hanshin Seiko. For small diameter holes at an angle, we will consider the processing method by checking not only the hole diameter but also the angle reference, entrance and exit positions, and the path through which the electrode passes. The thickness of the plate and the processing length along the axis of the hole are not the same. We will check the drawings, including any steps or intersecting holes, the surfaces that can be held, and the direction of approach for the electrode. If additional processing is required on supplied items where you want to preserve the finished surface, please inform us of any areas that need protection.

basic information
【Processing Method】 Fine Hole Electrical Discharge Machining 【Confirmation Items】 Material and hardness, hole diameter and tolerance, axial length of the hole, through/stop, reference for measuring angles, entrance/exit positions 【Setup Conditions】 Surfaces that can hold the parts, direction of electrode approach, interference with surrounding shapes, protection of processed surfaces This does not indicate a uniform upper limit for angles or depths. Individual feasibility will be confirmed based on the drawings and the condition of supplied items.
Price information
We will check the drawings, materials, hole diameter, angle, hole path, quantity, and holding conditions, and provide individual estimates.
Delivery Time
※We will confirm the drawings, quantities, condition of materials and supplied items, and desired delivery date, and provide you with guidance.
Applications/Examples of results
[Example of Processing Consultation] Consideration of the position of small diameter holes at an angle, additional holes for existing parts, and start hole for wire cutting. Please also indicate whether the holes will be used as finished holes or for subsequent processes. These are examples of consultation topics and do not guarantee individual manufacturing results or processing 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/
