Lightweighting is the current trend in the aerospace sector, so materials that can be used to reduce the weight of airframes, such as carbon fibre and glass fibre composites, are more widely used in aerospace manufacturing. Carbon fibre materials are used for their light weight, fatigue strength and mechanical properties and can withstand extreme environmental conditions and arbitrary loads, while glass fibre is used as an aerospace reinforcement material for its light weight, high strength, impact resistance and flame retardancy.

The disadvantages of carbon and glass fibres are that they are brittle, difficult to machine and prone to delamination, tears and burrs during production processing. WSS PCD tools offer solutions for these difficult composites.

Milling processing is generally a production processing method for finished workpieces into production processing, processing accuracy requirements are high, is the complex workpiece rough machining after the repair of the milling process. In the processing process, in order to reduce and prevent the occurrence of delamination, tearing, burrs and other difficulties in the composite material, Weiss through the control of the production process control parameters, such as tangential walking speed, cutting speed, feed, etc., to produce more accurate parameters before carrying out milling production processing.

As a milling edge, PCD tools have good wear resistance and are based on carbide with high stiffness and dimensional accuracy to guarantee the production and processing quality of milling. The laser engraved chipbreaker grooves on the PCD edge enhance chip evacuation and chipbreaking capacity, thus improving the production and processing efficiency, which is crucial for the milling production and processing of composite materials and the drilling production and processing.
