Ruby Tipped Coil Winding Nozzle/coil winding needles

Detailed description

Ruby Nozzle is made of two main parts, stainless steel and the processed ruby. It has been widely used in CNC automatic winding machine.
The Ruby Material has the characteristics of extremely hard and wear-resistant by precise processing and combination. The rigidity of ruby is above than level 9 and is just less than that of diamond. Ruby 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.
Product 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
Application:
Wire coiling of fine coil and thin coil of various automatic winding machines.
Work Limit: D1>0.2mm D1>0.7mm
