Coil Winding Nozzles - Ruby Tipped 

Ruby is the hardest among the materials selected for

coil winding nozzle entrance and exit.

Their single crystal (mono crystalline) structure allows diamond polishing to a mirror finish unmatched by other material,

reducing friction and protecting the wire.Shown at left is a

photomicrograph of a ruby exit orifice.

Issues with Ruby Tipped Nozzle
 

The body of a ruby tipped nozzle is usually made of a stainless steel tube that retains the longitudinal grains inherent to all hard drawn steel tubes, which will form a bulge in the bore when bent then straightened. Upon impact, the ruby tip either will be broken or fractured which may not be visible to the naked eyes but which nevertheless will damage the wire. Therefore, a ruby nozzle after impact should be discarded.

Key advantages of Ruby Tipped Coil Winding Nozzle:

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.
