We will introduce a case that achieved improvements in assembly accuracy, stable jig lifespan, and yield enhancement!

We would like to introduce a case study of deep hole machining on both sides of positioning shafts used in automotive molds and jigs. In this case, there were challenges such as the tendency for misalignment during dual-side machining and significant effects of thermal deformation. However, through our company's efforts, we were able to achieve improvements in assembly accuracy, stability of jig lifespan, and yield rate. Our company has many years of experience and advanced technology in the fields of deep hole machining and gun drilling. Utilizing our advanced gun drilling technology, which enables precise deep hole machining, we provide high-quality machining services tailored to our customers' requirements. 【Case Overview】 ■ Industry: Automotive molds/jig devices ■ Part Information: S45C, φ3×130mm dual-side machining, tolerance ±0.01 to 0.02mm ■ Challenges: Tendency for misalignment during dual-side machining / significant effects of thermal deformation ■ Provided Value: Established a stable machining process with eccentricity of 0.02 to 0.03mm and mass production capability ■ Technical Points: Multi-stage centering, optimization of dual-side machining sequence, warpage correction technology *For more details, please download the PDF or feel free to contact us.
