Flexure Resistance Tungsten Carbide Nozzle with Precision Grinding 

We supply high quality Tungsten carbide coil winding nozzle and Ruby tipped coil 

winding nozzle for Nittoku coil  winding machine, CNC Automatic coil winding machine

 and other brand coil winding machines,.     

There is description and features about the Tungsten Carbide Nozzle as following:

Tungsten Carbide nozzle is used on coil winding machine.it is made precisely of super 

hard alloy and enjoys the hardness over HRA90.degree while the anti bending degree 

reached over 2300N/mm.Two terminals and the inner and outlet are all receive mirror 

surface treatment to ensure enameled wire makes no scrape. High hardness, resistance 

to flexure, block and impact .

Key advantages of Tungsten Carbide 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 wireguiding 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 and description:

All size can be customized according to customer requirements 

The the measurements drawing as follow please confirm your nozzles size according

 to your winding machine and coil products.
