CNC Milling of Aluminum Chassis for a Personal Rescue Device

A customer that makes personal rescue devices approached Kilgore to 5-Axis CNC machine 50 aluminum chassis. We first CNC milled the 14.734” long, 8.649” wide and 2.641” high component using our Hass VF-4SS machine, which featured 1,000 PSI thru spindle coolant and a TR210 trunnion, which provided the necessary 5-Axis simultaneous motion and positioning.

After each of the 3.5 lbs, 6061 aluminum chassis were milled, they were polished and anodized to MIL-A8625 type II, class 1 specifications. During the entire process, the experts at Kilgore were able to hold tightest tolerances of ±.001”.
