Machining record for a worm gear with an outer diameter of φ860mm. We will machine precision keyways, taking into consideration the alignment of the rotation direction and the protection of existing surfaces.
At Hanshin Seiko, we process key grooves for large gears and worm gears using wire cut electrical discharge machining. We welcome inquiries about additional processing for parts with internal face key grooves or those requiring positional alignment in the direction of rotation. The example featured is the processing of face key grooves on a large worm gear with an outer diameter of φ860mm, an inner diameter of φ620mm, and a thickness of 100mm. In addition to the specified dimension of 41.95±0.01mm, we undertook processing that required alignment in the direction of rotation. We pay attention to fine rotational adjustments of large workpieces, position verification after fixing, and prevention of scratches on tooth surfaces and finishing surfaces. We manage the dimensions of the grooves and the processing positions separately, emphasizing setups that protect the existing shapes. We accommodate single items, prototypes, small lots, and additional processing for supplied materials. Based in Kobe, we accept processing inquiries from across the country. Please provide us with the drawings along with material, weight, condition of the workpiece, quantity, and desired delivery date.

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/
