Composites play an important role not only in electrical engineering. In aircraft and vehicle construction, too, the materials with high glass or carbon fiber content ensure optimum energy efficiency thanks to their exceptional strength and low weight.

Milling composites for the highest requirements

Composites place the highest demands on the process and tool, both in terms of machining quality and tool life. New materials in composites such as ceramic-based fibers and other extremely resistant and inhomogeneous materials require modern, technically sophisticated machining techniques and tools. Components made of composites basically require exact dimensional accuracy and excellent surface quality.

Hufschmied has developed innovative special tools for the machining of fiber-reinforced plastics, which make machining much more reliable and economical. Through intensive research and development, Hufschmied has succeeded in achieving the balancing act between high wear resistance and high cutting edge retention of the machining tool and, at the same time, high efficiency in terms of tool life and machining speed in its Fiber-Line tools.

Milling tools specially designed for “cold” cutting

Hufschmied drilling and milling tools have as an outstanding feature a chip geometry specially designed for the needs of “cold” cutting and sharp homogeneous cutting edges. Due to this cutting edge geometry and its formation, the plastic matrix materials in which the respective fibers are embedded are not heated. As a result, they remain harder and can be cut through more easily. The fibers are cut flush with the matrix and delaminations, fiber protrusions or fraying are avoided. All tools feature special carbides that are optimized for the wear mechanisms of fiber materials, as they occur in fiber-reinforced plastics.

Special chipbreaker geometries for reduced cutting force minimize the occurring process forces and additionally the process heat. This in turn prevents delamination, fraying or fiber protrusions on the components.

Hufschmied offers you a wide range of standard tools in a wide variety of dimensions. Our team will also be happy to support you with individual solutions for the machining of composites. Optimized milling programs from our in-house CAD/CAM department in engineering also ensure cost-efficient machining in any industry.
