Processing achievements of bevel gears with a 45° upper and lower irregular shape. We tackle the machining of complex tooth profiles through shape verification in CAD and innovative special jigs and processes.
At Hanshin Seiko, we accept consultations for the machining of bevel gears and upper and lower differently shaped parts using wire cut electrical discharge machining. The case presented involves the machining of a bevel gear with a 45° upper and lower different shape. We considered not only the different tooth profiles on the upper and lower sides but also the tooth surfaces connecting them, while examining the shape in CAD and developing the machining program. For complex shapes, in addition to creating the machining path, it is crucial to set up the holding of the product. In this case, we used a special jig and assembled the machining process to fit the product shape. Considering the machining program, holding method, and process as a whole is a key point of our approach. Please feel free to consult us about parts that have "a large inclination and unclear machining methods" or "different shapes on the upper and lower sides that make setup difficult." Along with the drawings and CAD data, please provide the material, dimensions, required precision, quantity, and desired delivery date.

basic information
【Processing Details of the Case Study】 Processing Target: Bevel Gear Processing Method: Wire Cut Electrical Discharge Machining Shape: Upper and lower asymmetric shapes at 45° Preliminary Consideration: Shape confirmation using CAD, creation of processing program considering upper and lower contours and tooth surfaces Setup: Holding with special jigs and process design tailored to the product shape *The 45° refers to the shape condition of this case study. It does not indicate the standard taper capability of the machine or its applicability to all materials and dimensions. The feasibility and accuracy of processing will be confirmed based on the drawings and holding conditions.

Delivery Time
※We will confirm the shape, create the processing program, prepare the jigs, check the processing process, and verify the equipment's operating status, and provide individual guidance. Please consult us with your desired delivery date.
Applications/Examples of results
【Processing Achievements】 Umbrella gears with upper and lower different shapes at a 45° angle were produced using wire cut electrical discharge machining. This is an example that combines shape verification in CAD, complex machining programs, and innovative special jigs and processes. 【Processing Consultations Available】 - Tooth profile machining for umbrella gears - Parts with different contours on the upper and lower sides - Special shapes with large inclinations - Parts requiring consideration of machining paths and holding methods - Complex shapes that are difficult to process with standard setups *This is a contract processing service based on drawings, not the sale of standard gears.
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/
