Processing results for a large SUS304 gear with a thickness of 300mm. Care is taken with the shape accuracy in the thickness direction and the alignment of the key groove to the outer peripheral tooth profile.
At Hanshin Seiko, we offer wire cut electrical discharge machining for thick stainless steel parts such as SUS304. The case presented involves the machining of key grooves for a large gear made of SUS304 with a plate thickness of 300mm. In addition to the shape accuracy in the thickness direction, "phase management" became important to align the angle and positional relationship of the key groove with respect to the outer circumference of the tooth profile. In thick material processing, we consider the deflection of the wire and the discharge of machining chips, and we examine wire tension, processing fluid pressure, and discharge conditions. We separate the roles of rough machining and finishing, and assemble the process while paying attention not only to the entrance and exit but also to the shape of the intermediate sections. We also take into account positioning based on the tooth profile and any changes in posture during fixation. Please consult us regarding key groove machining for thick parts and additional machining where the positional relationship with the tooth profile is specified. Along with the drawings, please provide the material, dimensions, weight, required tolerances, machining position, quantity, and desired delivery date.

Delivery Time
※We will confirm the drawings, quantities, setup conditions, and equipment operating status, and provide individual guidance. Please let us know the planned delivery date for materials and parts, as well as your desired delivery date.
Applications/Examples of results
【Processing Achievements】 Wire cut electrical discharge machining of a large gear made of SUS304 with a thickness of 300mm, focusing on the keyway for the shaft hole. This case required precision in the thickness direction and phase alignment with the outer circumference tooth profile. 【Processing Services Available】 - Wire cutting of thick stainless steel parts - Internal keyway machining for gears and mechanical parts - Processing that requires alignment based on the outer circumference tooth profile - Additional machining for large parts and supplied items - Processing that requires precision in the thickness direction *This is not standard gear sales, but a contract machining service based on drawings.
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/
