Hello Machine1. I am in the Tulsa area, Claremore. There are several possibilities to improve and or eliminate the chatter problem you are having. Possibly giving you up to 30% improved machining time. Anywhere from using a solid carbide shanked cutter, maximize your holder type or just plain going after chatter by frequency analysis with your existing setup. These are just a few idea's. We devise special cutters along with dynamic optimization methods. If your interested just email me. Thanks. Randy |
