Coil Winding Machine Tungsten Carbide Nozzle -1

TungstenCarbide nozzle is used on coil winding machine. It is made precisely of hard alloy and enjoys the hardness up to HRA90. Two terminals andinnerle are all receive mirror surface treatment to ensure enameled wire makes no scrape. High hardness, resistance to flexure, block and impact. 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 Straightness and Stiffness are defined by the wire exit being concentric and inflexible with respect to the nozzle locating? . In plain terms, the wire should exit from the nozzle concentric to the locating? To within 0.02 mm, with or without load. A geometric characteristic presentation is shown at upper left. Concentricity to within 0.01mm. 4. Precise Exit Radii Because the coil winding nozzle's Exit Radii governs the angle of the wire exit from one coil to the next, it should be monitored to + / - 0.025 mm. This is done by digital measurement, shown at upper right.
