Additional processing on shafts after lathe machining, hardening, and polishing. We will check the reference positions and angles for key grooves, D-cuts, and cross holes, and consider the holding methods.
At Hanshin Seiko, we accept special additional processing on supplied shafts that have been lathe-turned, heat-treated, and polished. Please consult us about key grooves, D-cuts, two-sided widths, notches, slits, lateral holes, small diameter holes, and irregular holes on end faces. We consider suitable methods for wire cutting, shape electric discharge, fine hole electric discharge, and machining based on material, hardness, and processing shape. We differentiate processing methods according to conditions such as through shapes, bottom shapes, and small diameter holes. For additional processing at multiple locations, we check the axis center, end faces, existing key grooves, and reference holes, taking into account the angular relationship between key grooves and lateral holes, as well as the phase of end face shapes. The polished outer diameter is considered for scratch prevention, and for elongated shafts, we examine the setup based on total length, diameter, processing position, and points that can be held. Please also consult us about additional processing due to design changes or outsourcing only the electric discharge processing steps. Along with a drawing that shows the entire shaft, please inform us of the current processing state, additional processing details, quantity, and desired delivery date.

basic information
Processing target: Supplied shafts that have been lathe-processed, hardened, and polished, etc. Processing shapes: Key grooves, D-cuts, two-sided widths, notches, slits, lateral holes, small diameter holes, and irregular holes on end faces, etc. Processing methods: Selected from wire cutting, shape electric discharge machining, fine hole electric discharge machining, and machining. Verification items: Material, hardness, total length, outer diameter/step diameter, processing position, angle/phase, tolerances, reference surfaces, polished areas, and the range that can be held. *The feasibility of processing is determined not only by the additional shapes but also by checking the overall dimensions of the shaft and the installation/holding conditions.
Price information
This is an individual estimate for each drawing. We will confirm the material, hardness, shaft dimensions, additional shapes, number of processing locations, angle specifications, required tolerances, quantity, and the preparation details for jigs and electrodes to provide the estimate.
Delivery Time
※We will check the condition of the supplied items, additional shapes, setup conditions, quantity, and equipment operating status, and provide you with information. Please let us know the scheduled supply date and your desired delivery date.
Applications/Examples of results
【Applications and Consultation Examples】 - Adding keyways to shafts for motors, gears, pulleys, and couplings - D-cuts and dual surface width machining for preventing rotation and component installation - Machining of lateral holes and small diameter holes for pin insertion, lubrication, and fluid pathways - Adjusting the angle relationship between keyways and lateral holes - Adding special shapes to shafts after hardening and polishing - Machining of square holes, irregular holes, and bottomed shapes on end faces - Additional machining due to design changes after trial runs *This is a contract additional machining service for supplied items, not the sale of standard shafts.
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/
