CNC Milling of a Mylar Washer for the Aerospace Industry

Due to our expertise in manufacturing washers from all types of materials, Shimco was contracted to produce a Mylar® washer for a customer in the aerospace industry. After reviewing the customer supplied specifications, we chose a CNC milling operation, rather than stamping or laser cutting, to produce the highest quality part possible. Utilizing our VMX Hurco CNC milling machines, we were able to quickly and cost-effectively mill and drill 30 units of this 7.201" x 1.302" x .062" washer according to the tight tolerances required by the specification. All parts were marked with the part number and underwent a rigorous quality control inspection before shipment to the customer in Quebec.
