Pitch Line Diaphragm (PLD)

The Forkardt PLD (Pitch Line Diaphragm) chuck is aimed primarily at gear families. This diaphragm chuck offers solutions in hard turning and grinding operations where repeatability, inter-changeability and roundness are a concern.

The key to the design of the Pitch Line Diaphragm (PLD) is the simplicity of the quick change system. A fixed length pin locates against the master jaw of the diaphragm and extends the distance to the pitch diameter. The pin is housed in a jaw that orients the unit and contains the “Quick Change” feature of a snap in place housing and retained screw system. Replacement of worn pin sets is as simple as sliding out the old and inserting the new. NO ADJUSTMENT is necessary.
