Repair of SKD11 vacuum heat-treated male and female blades. Check the condition of the damage and allowable dimensions, and consider reprocessing the blade tips while minimizing the amount of material removed.
At Hanshin Seiko, we accept repairs for cutter blades made of SKD11 vacuum hardening material. The case presented involves the repair of male and female blades used in ceiling panel molding machines. The focus was on removing scratches as much as possible while minimizing the amount of blade edge material removed. We assessed the depth of the scratches and the wear condition to determine whether repairs could be made with an additional removal of approximately 0.05 to 0.1 mm, and decided on the necessary processing amount. The blade edges were finished in multiple stages using wire cut electrical discharge machining, taking into account the required dimensional accuracy and surface roughness. For scratches other than on the blade edges, we combine hand finishing and polishing processes according to the condition. We welcome inquiries such as "I want to remove scratches from the blade edge" or "I want to minimize dimensional changes due to excessive grinding." Please provide us with drawings, photos showing the condition of the scratches, acceptable dimensional changes, quantity, and desired delivery date. *The additional removal amount is based on the conditions considered in this case. The feasibility of repairs and processing amounts will be provided after checking the condition of the actual item and the required specifications.

basic information
[Repair Conditions for Published Case Studies] Target: Cutter blades for ceiling panel molding machines Material: SKD11 Heat Treatment: Vacuum hardening Compatible Parts: Male blade and female blade Edge Processing: Multiple processing using wire cut electrical discharge machining Finishing Other Than the Edge: Manual finishing and polishing Consideration of Infeed Amount: Determine if it can be repaired with an infeed amount of approximately 0.05 to 0.1 mm *The infeed amount is not a machining tolerance. The required machining amount varies depending on the depth of scratches, wear, and allowable dimensional changes. Hardness, compatible dimensions, and finishing accuracy will be confirmed individually.
Price information

Delivery Time
※We will check the condition of damage and wear, necessary processing steps, quantity, and equipment operating status, and provide guidance. Please let us know the expected delivery date of the actual item and your desired delivery date.
Applications/Examples of results
【Repair Achievements】 This is a case of a cutter blade made from SKD11 vacuum heat-treated material used in ceiling board molding machines. The cutting edges of the male and female blades were refined using wire cut electrical discharge machining, and other damages were finished with manual polishing and grinding. 【Issues You Can Consult About】 - I want to repair scratches and wear on heat-treated cutter blades. - I want to reprocess while minimizing the amount taken off the cutting edge. - I would like to consult about the repair of both male and female blades together. - I want to request processing of the cutting edges and polishing and finishing of various parts. *This is not a standard product sale of cutter blades, but a repair and reprocessing service for supplied items.*
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/
