Chucker Machines

The Davenport five-spindle chucking machine is designed for medium- and high-volume secondary operation work on parts up to 2 1/4” diameter.

Significantly progressive in its adaptability to specific jobs, the Chucker version of the Davenport machine is used for secondary operations.

Optimum machining flexibility is provided through 9 tooling positions, while common operations such as; cross drill, cross tap, thread roll, mill, and slot can be complete using standard Davenport attachments.

Index time is as little as 0.4 seconds. Quick index & cycle time teamed with unparalleled machining…has allowed Davenport to be the most economical chucking machine available today.

Most tooling and attachments used on the Davenport Model B Bar Machine can also be used on the Chucker.

When cutting steel the threading spindle revolves in the same direction as the work spindle at a ratio of 3 to 4 while threading tool is running to work and 3 to 2 while running off.

When threading on brass work the threading spindle is stopped when tool is running on but revolves twice the speed of the work spindle to run off.
