We pride ourselves in our ability to tackle challenging parts, and this is one of our proudest accomplishments. We have developed a relatioship with the a high profile research institute at a major university and they have turned to us for several complex molybdenum projects, including this collector housing. This molybdenum housing is about 2.75" in diameter and about .75" deep.
The inner diameters were turned on a CNC lathe and required more intense programming than may be apparent in pictures. The depth of the bottom surface includes a taper on both its inside and outside surfaces which required careful machining from both sides.
The outside diameter of the house could not be turned because of the flat mounting pads that protrude beyond the major diameter of the rest of the housing. A special fixture had to be built to hold the delicate housing for circle milling. The groove visible in the side of housing has a complex profile as well which added more challenges where it meets the mouting pads. This was machined in our 4 axis CNC machine. The outer rings each have 2-56 tap holes and the 4 hole pattern on the flat pad on the side of the housing are 0-80 tap holes.
The flex ring is a scaled down version of a similar project we have built for the same customer in the past. Though it appears simple it is a very delicate operation on the 4th axis machine with another special fixture created to hold it. This is especially necessary since the piece does not leave any easy way by which to hold it.
