Small Pathway and Deep Hole Fine Hole Discharge Machining | Consideration Based on Hole Diameter and Depth
Concerned about the breakage of thin drills in deep holes. Check the feasibility of processing by combining hole diameter, depth, and material.
We can discuss contract processing for small-diameter, high-aspect-ratio deep holes using fine hole discharge machining. We will consider methods for machining holes that are difficult to process with cutting tools after hardening, using thin pipe-shaped electrodes. Even with the same hole diameter, conditions vary based on depth, machining direction, wall thickness to the end face, and the presence of intersecting holes. Please provide drawings that indicate the finished hole diameter and tolerance, depth, whether it is through or blind, and hole position. We will confirm the flow of processing fluid, discharge of chips, and the required hole quality. The electrode diameter and finished hole diameter, as well as the Z-stroke of the equipment and the possible hole depth, are not the same. We do not guarantee a uniform combination of specific hole diameters and depths. The image is for explanatory purposes related to the original article.

basic information
【Method】Fine Hole Electrical Discharge Machining 【Confirmation Conditions】Material, heat treatment, finished hole diameter and tolerance, hole depth, through/stop, number of holes, hole position, machining direction, workpiece shape, thickness to the end face, intersecting holes 【Quality Confirmation】Confirm the required hole diameter accuracy, straightness, and internal surface condition in advance It is not sufficient to determine feasibility based solely on whether the electrode can reach. The hole diameter and depth, supply and discharge of machining fluid, and surrounding shape must be confirmed to consider the machining method.
Price information
We will confirm the hole diameter, depth, material, number of holes, position, direction, required quality, and quantity of parts, and provide a quotation for each drawing.
Delivery Time
※We will confirm the drawings, number of holes and parts, condition of materials and supplied items, and desired delivery date, and provide guidance accordingly.
Applications/Examples of results
【Application and Processing Consultation Examples】 Small holes in mold components, precision nozzles, parts for fluid and air passage, cooling holes, and small diameter holes in long parts. These are application examples and do not indicate delivery performance for individual cases. For flow path applications, it is confirmed whether the necessary hole quality can be met in addition to the holes being created.
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/
