Metal wire drawing process for deep wire drawing

The invention discloses a metal wire drawing process for deep wire drawing, and belongs to the field of metal wire drawing. The metal wire drawing process for deep wire drawing comprises the following steps: S1, performing wire drawing by adopting a flat pressing type abrasive belt: firstly, fixing a workpiece on a die, rotating a grinding abrasive belt at a high speed, pressing a pressing block on the back surface of the abrasive belt downwards to polish the workpiece, and spraying a polishing solution and polishing particles while polishing. According to the process, the wire drawing effect is improved by adding the polishing particles, the texture depth is increased so that the texture can be clearer, weld joints, residues and scratches on the surface of the workpiece are effectively removed through the polishing auxiliary aggregate, the uniformity of the surface of the workpiece is improved, and the texture depth is effectively increased through the texture friction aggregate; and meanwhile, in the wire d
