Wire-Running Lead Screw


The wire-running lead screw is a key transmission component of the reciprocating drive system for the wire spool drum on WEDM machines, controlling uniform wire winding and stable tension on the drum. Common specifications include M20×1.25×415 and M18×2×420. Made of high-strength alloy steel with tempering treatment and precision thread machining, it offers high lead accuracy and good surface finish. With proper clearance between the screw and nut pair, the reciprocating motion is smooth and free of stick-slip, ensuring the molybdenum wire winds neatly in orderly layers on the drum to prevent overlapping and jamming. Wear of the wire-running lead screw directly affects winding quality, wire tension and machining stability — an important component requiring regular inspection and maintenance.
