Our recent project manufacturing custom pins showcased the attention to detail our team brings to complex machining tasks. To meet our client’s exact specifications, we went through three rounds of trials, each one refining our process to reach the highest standards. Here’s a breakdown of our journey to the perfect pins:

In Trial 1, we started with standard turning and used VMC (Vertical Machining Center) for angled faces, followed by heat treatment, cylindrical grinding, and wire-cutting for the dowel hole. While the initial stages went smoothly, we observed slight deviations in the angles during the final finishing stage.

For Trial 2, we made adjustments to the VMC process. However, the 4th-axis device posed repeatability issues, and the angles continued to show minor inaccuracies. This prompted us to consider a different approach for achieving the correct specifications.

In Trial 3, we switched to wire-cutting for the angle faces and used a specially designed indexing fixture. This change provided the control needed to hit the precise angle requirements, with no deviations in the final product.
