CNC Routing Extruded Grade Nylon: Techno HD CNC Router Time Study
Techno CNC Systems completed a CNC time study on an HD Model 4896 CNC Router using a 4 HP HSD spindle and an upcut spiral O'flute Onsrud 63 Series cutter. The piece machined is extruded grade nylon made by Invista with sections of an adhesive coating (green areas) used in the automotive industry. This application required extra attention toward the adhesive material as it tends to flake or deform if not cut correctly. Techno's engineers ran several tests finding the optimum speed for the cut while achieving a desired edge finish the customer was seeking. It was determined during this study custom fixturing would be required to support the extrude grade nylon on it's top profiled cross section to minimize the extrusions tendency to vibrate. With this custom fixture a high rate of speed can be achieved to cut this material in a production environment.
