Tungsten carbide wire guide nozzles(Coil winding nozzles)used in coil winding machines to guide the wire to wind in the bobbin, pins and etc. For the manufacture of coils, motors, transformers, relays, inductance and sensors in automotive, telecoms, electric and electronic applications. Features: 1. High Wear Resistance This is assured by the choice of materials for wear elements possessing a minimum hardness in excess of Vickers 1, 000 (HRC 70). 2. Scratch-Proofing Eliminate wire insulation film damage, low friction resistance, stable wire tension. The wire-guiding surfaces are mirror finished by diamond lapping to a surface roughness of 2 -4 micro inches Ra or better, material permit. 3. Straightness and Stiffness
