Product Example 4: Diameter

The Dow-Gage pictured above checks the outside diameter of a small shaft with an adjacent shoulder.  The Special Stage Set locates the part in a precision ground "V" while the shoulder of the part stops against the outside face of the "V" block. The Dow-Gage is set to "0" with the Set Master which is pictured in the foreground.  The outside diameter of the production parts is then compared to the master setting. Checking rates in excess of several hundred parts an hour are possible.
