High Precision Wire Guide Needles Coil Winding Nozzle Motor Nozzle

Detailed Product Description:

Tungsten carbide nozzle also call wire guide tubes or wire guide needles.
Made by the precision machining with the tungsten carbide materials (super hard alloy). The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. We do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging has been improved comparing with the ruby nozzle.

Product Features:

1. High Wear Resistance This is assured by the choice of materials for wear elements possessing a minimum hardness in excess of Vickers 1, 000 (HRC 70).

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.
