Solid milling cutter

glass fiber-reinforced composite

LMT Onsrud’s GRP Mill for Glass-Reinforced Plastic Applications Fiberglass or glass-reinforced plastic is a composite material composed of glass fibers acting as a reinforcing agent when combined with a plastic or polymer resin. This material can be designed in layers oriented in various directions, in a chopped strand mat or through a pultrusion process; all to achieve the desired stiffness and strength needed for the application. Cutting these various lay-ups can be difficult in that the cutting geometry must include both a shearing of the glass fibers while creating a chip which removes heat from the cut to avoid melting of the material.
