Description

The Dead-Length Spider-Stop Step Chuck is designed to handle workpieces larger than the standard 16C Collet or Step Chuck. There is a spider stop which slides through oversize slots in the step chuck and locates against the collet seat in the machine's 16C spindle. A stop button screws into the spider stop and can be machined to locate against the reference location on the workpiece. This system requires a standard extra-depth step chuck closer.  Closer (16-2683-OC) is required with a 3" chuck, and closer (16-2684-OC) is required with a 4" chuck.

The Spider-Stop Step Chuck has only one moving part, the step chuck. This allows for much better concentricity than the standard dead-length collet system, even for smaller diameter workpieces.

The step chuck is first machined to the chucking diameter of the workpiece and to a depth to accommodate the stop button. The stop button is machined to the locating surface of the workpiece. The stop button is assembled. The unit is mounted into the spindle of the machine that already has the appropriate step chuck mounted. With the closer in the open position and the workpiece held against the stop button, the draw tube is turned until the step chuck just grips the workpiece and then backed off 1/2 a turn. The part should easily load into the step chuck. The closer is locked in this position. With the part firmly located against the stop button, the step chuck is closed.

It is important that the stop button be lightly faced after the unit is mounted in the spindle to ensure extremely precise perpendicularity with the locating surface.
