Tungsten carbide wire guide nozzles(motor coil windingnozzles)used in coil winding machines to guide the wire to wind inthe bobbin, pins and etc. For the stators and rotors in Series,cooling fans, micro-motor and the motor industries.

Features:
1. High Wear Resistance.
This is assured by the choice of materials for wear elementspossessing a minimum hardness in excess of Vickers 1, 000 (HRC70).

2. Scratch-Proofing
Eliminate wire insulation film damage, low friction resistance,stable wire tension. The wire-guiding surfaces are mirror finishedby diamond lapping to a surface roughness of 2 -4 micro inches Raor better, material permit.

3. Straightness and Stiffness
Straightness and Stiffness are defined by the wire exit beingconcentric and inflexible with respect to the nozzle locating? . Inplain terms, the wire should exit from the nozzle concentric to thelocating? To within 0.02 mm, with or without load. A geometriccharacteristic presentation is shown at upper left. Concentricityto within 0.01mm.

4. Precise Exit Radii
Because the coil winding nozzle's Exit Radii governs the angle ofthe wire exit from one coil to the next, it should be monitored to/ - 0.025 mm. This is done by digital measurement, shown at upperright.

Measurements:
Customize available by requested, outside diameter is governed bynozzle wall thickness. Confirm your nozzles measurements accordingto your winding machine and coil products.
