A customer in the pump manufacturing industry identified an application with a keyway that was milled into a treaded bore located above a smaller through bore without a relief hole. This keyseat miller would be designed with a long pilot passing through the threaded bore and bearing into the lower smaller bore. We then milled a slot in threads without breaking into the smaller bore with finished dimensions of .625” in width and .310” in depth. Dimensional, visual, and functional inspections were completed to ensure manufactured tolerances within +/- .0002”. At National Machine Tool, our lead time for stock items is 2-3 days and custom items in 2-3 weeks. For more information on this project see the table below or contact us directly.
