Achieving surface roughness that improves the durability of molds! Processing results from profile grinding after wire cutting.

We would like to introduce a case study of high-precision punches for gears used in fine blanking molds. Our company has established a high-precision processing room with thorough temperature control, and we carry out high-precision machining. We also achieve surface roughness that enhances the durability of the molds. The material used is HAP40, and the product size is φ60 x 60(mm). This is a machining achievement for the automotive industry. 【Case Overview】 ■ Case Study: High-precision punches for gears used in fine blanking molds ■ Industry: Automotive ■ Machining Method and Process: Profile grinding from wire cutting ■ Product Size: φ60 x 60(mm) ■ Material: HAP40 ■ Customer Feedback: "For the gear components, precision was of course important, but the durability of the mold during mass production was also crucial. There were no issues with breakage over long periods." *For more details, please download the PDF or feel free to contact us.
