Tungsten Carbide Alloy Coill Winding Machine Wire Tube Nozzle Wire Guide Needle
Material: It is made by the precision machining with the tungsten carbide materials (super hard alloy).
Feature: The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm.
Surface finishing: 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.
Good for winding: 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.
