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.
