Dovetail Workholding for Quick-Change Fixturing
A dovetail fixture locks the workpiece or sub-plate into a matching dovetail groove — so it seats to the same datums every time with a single pull-down. JIYAN dovetail workholding pairs dovetail zero-point clamps with dovetail-mount self-centering vises, giving you sub-minute changeover on the mill and full five-face reach on 5-axis. Every part is machined, heat-treated, ground and CMM-inspected in-house.

Pick the right dovetail workholding
Clamp vs vise
A dovetail zero-point clamp locates and holds a pre-machined sub-plate. A dovetail-mount self-centering vise grips raw stock while sitting in the same dovetail base — use both on one table for mixed work.
By station count
Single and 2-station clamps suit one-off and paired parts. 4-station cubes and towers multiply parts per setup for high-volume runs and lights-out cells.
By axis
Long and twin-base dovetail clamps reach five faces on 5-axis. Round dovetail clamps drop onto rotary and 4th-axis work without re-indicating.

Dovetail workholding questions
What is a dovetail fixture and when do I use one?
A dovetail fixture uses a matched dovetail groove to pull a workpiece or sub-plate down and lock it to fixed datums in one motion. You use it whenever you want to swap parts or pallets in seconds without re-indicating — most often on 5-axis and high-mix milling where setup time is the bottleneck.
How does dovetail workholding improve changeover?
Because the dovetail seats the part to the same datums every time, you stage work off the machine, drop it into the groove, and tighten. Changeover drops from minutes of indicating to seconds, which is what makes lights-out and robot-loaded cells practical.
Can dovetail clamps be used for 5-axis machining?
Yes. Long and twin-base dovetail clamps hold the part low and clear of the toolpath, so you can machine four or five faces in a single setup. The dovetail also resists the lifting forces of aggressive 5-axis toolpaths.
What is the difference between dovetail and zero-point clamping?
They are the same family: a zero-point clamp is the receiver, and the dovetail is the geometry that pulls the pallet down and locates it. JIYAN's dovetail zero-point clamps combine both — locate and clamp on one pallet face, repeatably.
