The circular base of precision flat pliers is a key functional accessory, mainly used to provide 360 ° horizontal rotation capability for traditional flat pliers (especially precision combination flat pliers), enabling the workpiece to be positioned at any angle in the horizontal plane, thereby reducing secondary clamping and improving multi-faceted machining efficiency. The following is its technical analysis and application guide:

1, Core functions and values
1. Free angle adjustment
-Realize stepless rotation through the bottom worm gear or gear mechanism (commonly manual type), or use a servo motor to achieve CNC indexing (automated type).
-Division accuracy: manual type can reach ± 0.05 °, CNC type can reach ± 0.001 °.
2. Reduce the number of clamping times
-Multiple milling, drilling and other processes can be completed in one clamping of the workpiece, avoiding repeated positioning errors.
3. Strong compatibility
-Can install various types of pliers (including combination), three jaw chucks, and even customized fixtures.
