The Davenport five-spindle chucking machine is adaptable to 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 drilling, cross tapping, thread rolling, milling, flycutting, and slotting are accommodated through the use of standard Davenport attachments.

Idle time is only .4 seconds. This idle time, teamed with unparalleled machining versatility, has allowed the Davenport to become the most economical chucking machine on the market today.

All tooling and attachments available for the Davenport Bar Machine can also be used on the Chucker.
