Ruby Tiped Coil Winding Nozzle

Ruby nozzle: The product is made of stainless steel and ruby by precise processing and combination. The rigidity of ruby is above than the level 9 and is just less than that of diamond. It is a single crystal and can be made with high brightness and cleanness. It can effectively protect paint film and long-term continual work to ensure the high insulation of wire coil suffers no hurt. Features: 1. High Wear Resistance This is assured by the choice of materials for wear elements possessing. Hardness Value: 1800 ~ 2200Vickers, or 3times that of case hardened steel. Body material is stainless steel for structural supports, not wear-bearing. 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. Specification: Measurements: Customize available by requested, outside diameter is governed by nozzle wall thickness. See the measurements drawing to confirm your nozzles measurements according to your winding machine and coil products. Processing limit: D1≥ 0.2mm, D1≥ 0.7mm. Sapphire Nozzles(Ruby nozzle) Outside diameter: 0.60 ~ 20.00mm, tolerance: 0.004 ~ 0.03mm Inner diameter: 0.04 ~ 12.00mm, tolerance: 0.003 ~ 0.10mm Length: 0.40 ~ 15.00mm, tolerance: 0.02 ~ 0.10mm Taper: Custom design, tolerance: +/-3° Surface roughness: Rz0.05~Rz0.2 We offer other specifications and special products according to your requirements.
