Hard materials, long chips, high process forces: In mechanical and plant engineering, challenges like these can slow down production. VibroCut, based in Chemnitz, addresses these issues with vibration-assisted processes. 

In manufacturing, every micrometer counts—especially when machining quartz glass, silicon carbide, or ceramics. These materials are hard, brittle, and delicate, and their unique properties make high-tech applications possible. At the same time, they pose enormous challenges for machine tools.This is exactly where VibroCut comes in. The Chemnitz-based (Germany) company develops solutions for what is known as hybrid machining. It supplements traditional machining processes with targeted ultrasonic or oscillatory movements. The idea behind this is that the additional movement alters the contact between the tool and the workpiece—and can thus reduce forces, improve chip formation, or enhance machining quality.For designers and developers, one question is particularly crucial: What benefits does the technology offer in a specific process? The answer depends on the material, the geometry, the tool, and the required quality characteristics. VibroCut offers applications for drilling, grinding, turning, and friction stir welding. According to the company, the systems can be integrated into new machines or used with existing equipment.
