Diaphragm turning chuck

Northfield Precision offered a workholding solution for Chicago Dial Indicator, a leading American manufacturer of Electronic & Mechanical indicators. A Northfield 6-inch 10,000 rpm totally sealed 1-micron T.I.R. diaphragm chuck with special jaws and stop were used to enhance and increase production of machining the two bores that guide the indicator rod. These bores must be perfectly in line for an accurate indicator. Two fixtures are used to hold the brass indicator housing before the fixture/housing is placed in the chuck. One side is machined, the fixture is turned over, and the second side is machined. Alignment of 1/10,000 T.I.R. is achieved from bore to bore.
