CNC Horizontal Milling of Aluminum Mounting Block Component for the Defense Industry

PORTFOLIO: Mounting Block

Edgar Industries was asked to improve upon the manufacturing time and efficiency of a particular aluminum mounting block already in production for a DoD application. Our client manufactured 2 blocks at a time, the whole process taking 26 minutes. Through our own examination of customer-supplied print and 2D CAD drawing designs, we developed a production strategy that would speed production without sacrificing design quality.

By way of a MAZAK NEXUS 5000-II horizontal milling machine with a 160 too changer and a two-pallet loader, we were able to build the 6061-T6 aluminum blocks with perfect tolerance range. Using two Chick Work Holding Systems – one mounted on each of the pallets – we were able to machine 4 blocks in under 20 minutes. In addition, we were able to “keep the spindle turning” by loading and unloading one Chick Work Holding System, while the other pallet was in the machining chamber
