Coil winding wire guide nozzles, Hard Alloy Nozzle(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 .

Coil winding nozzle guides(Hard alloy nozzle)Tungste carbide wire guide nozzles 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.

Ruby tiped coil winding nozzle guides are used on coil winding machines and cable machines for wire guide.it is made of stainless stee and ruby by precise processing and combination.The rigidity of ruby is above than level 9 and is just less than that of diamond.Ruby tiped coil winding nozzle guide is a single crystal and can be made with high brightness and cleanness. It can effectively protect paint film and ling-term continual work.
