Examples of yield improvement and cost reduction in metal processing due to changes to through holes.

By reducing the number of cutting tools used by one, it is possible to lower costs as processing time can also be shortened!

We will process a stop hole with a diameter of φ6H7 and an effective depth of 7mm in a thin plate with a thickness of 8mm. In this case, it is necessary to machine the hole as close to being through as possible and finish the bottom of the hole to a flat surface. Therefore, we will process in the following order: [φ5.0 drill → flat end mill → chamfering → φ5.9 end mill → φ6 reamer]. One issue is that reamers with larger cutting edge surfaces cannot be used, which can cause the entrance to become misaligned and larger, leading to reduced yield. If there is no problem with the pilot hole being through, we can omit the machining with the flat end mill by making it a through hole. As a result, the number of cutting tools used is reduced by one, and machining time is also shortened, which helps to lower costs. [Case Study] ■ Content: Improvement of yield and cost reduction in metal processing by changing to a through hole ■ Issue: The entrance becoming misaligned and larger, causing reduced yield ■ Proposal: Make it a through hole if there is no problem with the pilot hole being through ■ Application: Cost reduction, cutting processing, machining, lathe work, precision processing *For more details, please refer to the PDF document or feel free to contact us.
