CNC clamp

The utility model discloses a CNC (Computer Numerical Control) clamp, relates to the technical field of numerical control machining, and can realize rapid clamping of a longer workpiece and improve the production efficiency. A CNC clamp comprises a rack, a clamping table, a clamping mechanism and a workpiece detection mechanism. The clamping table is arranged on the rack. And a mounting groove is formed in the clamping table. And the mounting groove is matched with a bulge on the workpiece. And a plurality of magnetic blocks are inserted into the clamping table. The multiple magnetic blocks are used for attracting workpieces. The clamping mechanism is arranged on one side of the clamping table and used for pushing the workpiece to abut against the clamping table. The workpiece detection mechanism is arranged on the rack and located at one end of the clamping table. Rapid positioning of the workpiece and the clamping table can be achieved through the mounting groove, the workpiece can be rapidly attracted to t
