Straightness Tungsten Carbide Nozzle / Grinding Carbide Needles for Bobbin Winding Machine

Coil Winding Nozzles / Wire Guide Tubes With Precision Grinding

Coil winding wire guide Nozzles(TungstenCarbide nozzle)also call wire guide tubes,

wire guide eyelets, wire guide needles, it 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.

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:

Above is just for example all size can be customized according to customer’s special dimensins drawing requirements .

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

to your winding machine and coil products.
