Zinc Die Cast Motor Housing
Weighing less than 1 lb., this zinc motor housing casting was designed to be used in an electric motor assembly and sent to us for finish machining. Our experienced staff worked with the client to create a custom fixture to fit multiple parts on our vertical CNC milling machine, which is equipped with an indexer, so that the parts could run in a single setup without stopping for changeovers. By utilizing CNC milling processes of drilling, tapping, and precision boring, we finished the 3.50" x 3.50" x 1.50" part and applied a 63Ra finish. Our manufacturing tolerances were maintained to .005" for flatness and .0005" on bores. CMM inspection of each part ensured that the job was completed to our highest standards.
