Various types of multiple-spindle vertical, automatic chucking machines are available. The machines include a carrier with six or eight equally spaced vertical columns encircling a stationary column. On the column over each spindle (except at the loading station) are combination (multiple-tool) heads.

Each spindle and head comprises a station or machining unit having independent feed and speed controls for maximum flexibility and efficiency. Each station is set up to perform specific operations in sequence with the next station, so that one carrier cycle around the column produces a finished workpiece.
