[0002] Currently, CNC machining centers use vises to clamp workpieces.

[0003] Chinese Patent Publication No. CN205147853U discloses a CNC machine tool machining fixture, comprising: a base; a positioning plate for placing the product to be processed, the positioning plate being fixedly mounted on the base, and an electromagnet disposed within the positioning plate; and a clamping member located on the positioning plate, the clamping member cooperating with the electromagnet to fix the product to be processed on the positioning plate. This CNC machine tool machining fixture utilizes the attraction force between the electromagnet and the clamping member to fix the product to be processed. Because the attraction force generated by the electromagnet is large and stable, it can firmly fix the product to be processed, thereby helping to improve the stability of CNC machine tool machining and increase production yield. Furthermore, since the attraction force generated by the electromagnet is not affected by the structural characteristics of the product to be processed, the CNC machine tool machining fixture can be applied to different types of products.

[0004] The CNC machine tool fixture mentioned above first places the workpiece on the fixture's placement platform and uses magnetic force to fix the workpiece when clamping it. However, when cutting ferrous workpieces, iron filings will be attracted to the fixture. As processing continues, the filings will accumulate on the fixture, which may affect normal processing.
