[Case Study] For those struggling with mass production processing of needle bearing retainers.
Reliable precision and shape guarantee system with NC machining! We have many years of diverse processing experience.
We received a request from the robot industry, stating that "there are no manufacturers capable of finishing to the exact shape as per the drawings." In this product, there is a deep groove on the inner diameter side, and tools capable of processing this are not available on the market. Therefore, our company manufactured a dedicated cutting tool to achieve the processing. We have received particular praise for our shape guarantee. If you have issues such as reducing defects in subsequent processes, please feel free to consult with us. 【Recommended for the following people】 ■ Those who frequently experience shape defects, leading to increased acceptance inspection workload. ■ Those whose accuracy is unstable, causing defects in subsequent processes and worsening direct delivery rates. ■ Those who want to strengthen their supply chain in response to BCP measures. ■ Those who urgently need to select an alternative supplier due to the current manufacturer going out of business. *For more details, please refer to the related link page or feel free to contact us.
