The DST series is an indexable work-holding tombstone. Designed to be mounted on the pallet of machining centers, the DST allows versatile maching without rechucking. The drive uses a roller gear cam mechanism for smooth rotation and self-locking in any position. The output shaft is held rigid enough for heavy grinding and finishing work. Furthermore, the unit is self contained and can be mounted on pallets in multiple places, each without sensors or other means of drive sources. To turn, attach the special bar to the main spindle and use the arc interpolation feature of the NC to rotate the cam follower on the disc.

•Allows machining to five different surfaces with tour horizontal machining center.
•Mechanism's zero backlash design provides high accuracy indexing motion.
•Does not require an independent input drive source, signal wire or control cable.
