Burhoe Machine Works produces products ranging from large aerospace and submarine components that are man rated and 100% inspected, to minuscule medical components used in the construction of devices that will be inspected by a microscope and implanted in human bodies to help perform tasks necessary for life.

Magnet Outer Casing

Burhoe Machine Works was contacted by our customer to manufacture a small run of magnet casings used in an undersea microwave application. The project was put to bid to several machine shops and Burhoe Machine works was awarded the contract. The part manufacture included a multiple step heat treat process in an inert gas environment. Roundness on a 14” diameter thin wall part was held to less than .001”. Burhoe Machine works completed the work on time, in less than three weeks.

Machining took place at our modern 9,000 square foot facility, and was subjected to our rigorous testing and quality controls including dimensional inspection, visual inspection, and first article inspection reporting. This part was also RoHS compliant. Typical turnaround time for a project of this magnitude is 3 – 5 weeks.
