Proposal of a progressive die including reamer hole finishing through precision shearing processing! A case where secondary cutting could be eliminated.

This is a technical proposal case aimed at rationalizing reaming processes for products that underwent reaming finishing after press processing. In this case, the product required precise hole diameters, and reaming finishing was performed after pressing. However, there were challenges related to the lead time and machining costs associated with secondary cutting. By setting an appropriate production lot size based on production performance and regularly maintaining the cutting tools used for finishing the reamed holes, stable mass production was achieved. 【Case Overview】 ■Challenge: Lead time and machining costs associated with reaming finishing after pressing ■Proposal: Progressive die including reaming finishing through precision shearing processing *For more details, please refer to the related links or feel free to contact us.

We can provide consistent support from prototype development to mass production using molds. We can accommodate plates up to 6 mm and will create molds that combine the application of cold forging technology and precision shearing processing. While a certain level of initial investment is required, there is potential for significant cost reduction compared to existing methods. Please consider utilizing our services for transitioning from existing methods to pressing and for the development of new parts in your press production facility.
