Composite materials based on natural fibers are currently trending. Their clean, post-processing-free milling presents a challenge, as the fibers are significantly harder to cut than conventional materials. Hufschmied presents the solution with T-REX (194/198). Thanks to its unique cutting geometry, this tool performs a compression cut that allows for smooth edges.
Two more tools are in the spotlight. 068ECO features a new milling cutter geometry developed in collaboration with aerospace users based on the proven HEXACUT geometry. Particularly for large components, the vibration behavior of the components has been significantly reduced, lowering the requirements for component clamping. The cutting pressure is particularly low with the 068ECO series. Also new: the 108 series of FIBER-LINE tools. The carbon milling cutters are available in various tooth types. In combination with wear-resistant hard metals and coatings, highly abrasive materials can also be processed.
Diamond coating DIP7
In addition to tool geometry, the coating also has a significant impact on the behavior of milling tools. For CFRP machining in aircraft construction, Hufschmied recommends its highly wear-resistant multilayer diamond coating DIP7. The gradient-free layer thickness ensures a homogeneous wear pattern and the high thermal conductivity allows for rapid heat dissipation. Thick-walled CFRP components can be processed reliably with tools coated with DIP7. The cutting edges are so sharp and the coating so smooth that the fibers do not snag and the components do not begin to vibrate. Uniform workpiece surfaces are produced without delamination or fiber protrusions.
Ultrasonic cutting
Co-exhibitor at Hufschmied's stand is SoniCut GmbH. Hufschmied's solid carbide monoblock blades enable the full potential of SoniCut's ultrasonic-assisted cutting systems to be utilized and are also sold together with them. This cutting method is particularly recommended for fragile honeycomb panels or fiber stacks.
