Customer having issues with setting up a variety of products

The issue

With a high-mix small-lot production system, it is difficult to pass down adjustment and engineering techniques. Because it is not possible to quantify them, it is not possible to reduce time and stabilize production.

After implementation

By implementing our Centerless Grinder with automatic setup support function, it became easier to reproduce the setup and cut down setup time by 72%. With this, even a beginner can use the same setup as a highly skilled worker.
