Several recent processing instance for aviation manufacturing cutting tool performance improvements:

(1) Processing Example 1: a commercial aircraft parts suppliers in the processing of a fiber-reinforced composite material workpiece with a solid carbide cone drill at a thickness of 0.200 "(5mm) material on drilling, each Drilling number substantial support drill only drilling 150 to 200 wells, you will have to replace the failed fiber tear tool the suppliers to switch to a new type of CVD diamond coated carbide drill to 2200 holes. despite the cost of the new bit old-fashioned drill 15 times longer bit life, reduced the number of tool changes, increased processing time, so still a 80% reduction in processing costs per hole.abrasive disc

(2) processing instance: Lockheed composite wing skins for the F-35 Joint Strike Fighter the seams dressing machining, cutting tool life and cutting edge quality is far from satisfactory. To this end, the development of a new type of CVD diamond coated tools, tool life (processed straight length) from 9 feet (only 1/3 of the cutting material thickness) to 57 feet (cutting material thickness), which available 2 equipped with a 24mm blade knife to processing a wing skins. Thus, the cost-effectiveness of $ 80,000 for each aircraft, is expected to save money (to reduce costs) amounted to $ 222.6 million for the 2783 F-35 fighter manufacturing plans for the U.S. market.cut off wheel
