Project of the week is a 7075-aluminum adapter plate we designed and machined for a client to convert an original diesel engine transmission to an electric vehicle. Picture on the far left was an original hand sketch that the customer provided to us for modeling. The next 2 photos are the first concepts we developed for approval, 3rd photo is the system connected and complete to validate size and fit for mounting. Last photo is the first prototype sample for trail fit and function testing. Part is roughly 14-1/2" x 11-3/4" x 4" machined from a solid billet 7075 and 6061 aluminum plate.
End Mills, Ball Mills and Chamfer Mills were solid carbide from IMCO with standard High-Speed Drills and taps for the small bores and tapped holes. Large bore was done on a CNC Lathe with a carbide tipped boring bar. No special fixturing is required to hold this. Part tolerance except the large bore is +/- 0.020 and a machine finish with chamfer edges is fine for this part. The large bore is used to align the mating components with a +0.010/-0.000 tolerance. Nice project to start this week of 06/23/13. If you have similar projects like this and would like to receive a quote from us, please reach out to us for further information.
