The NEW EXOPRO® AERO-HBC Herringbone Router

The OSG AeroHBC is a herringbone style router for high feed rates and excellent surface finishes in difficult to cut carbon fiber composites and Nomex honeycomb sandwich materials. It features a compression cutting mechanism to reduce the tendency of flagging in honeycomb materials.

Upshear, Downshear and Herringbones

We often get asked about the advantages of different types of cutters by machine shops who are starting to move from metals based machining to composites.  Here's a short explanation. Upcut or upshear routers will pull the chips up and out of the cut. Most standard end mills and routers operate this way.  Downshear routers leaves a crisper, cleaner edge on the top surface of the material because they push the chips downward into the material. Herringbone cutters, also called compression routers, combine the two for the cutting of laminates, honeycomb or any two sided material.  It virtually eliminates chipping, or flagging, on both sides for cleaner edge surface finishes. It also prevents the delimitation of the surface materials that sandwich the honeycomb together.  In a herringbone cutter the bottom portion is upshear and the top portion is downshear.
