CNC Machining and Anodizing of Mounting Plate for an Electronic Control Box

This project exemplifies EMD Controls & Fabrication’s ability to produce precision machined parts. The part shown was designed for mounting PC boards and other components in a NEMA 4X electronic control box in the weighing industry. Composed of only 6061 aluminum plate, the customer supplied drawings called out an overall size of 8.59″ x 8.59″, with a height of 1/4″.

Manufacturing of this component required extreme precision to create the intricate features. At EMD we pride ourselves in ability to machine these parts to a tolerance of only one thousandth of an inch.

Each finished plate was also finished to round the edges and various holes were tapped for 5-40 threads. The plates were then anodized by our subcontractor and metal inserts were driven into the appropriate locations. We manufactured this plate in quantities of 25 to 250, with lead times of 2-1/2 weeks.
