Product Details:

carbide tungsten steel needle (nozzle) processing instructions
1), the precision machining product selects the high quality tungsten carbide material.High hardness over HRA90, bending strength is as high as more than 2300 n/mm.Adopt the special process equipment for the product on both ends of the inner hole and into the outlet into the mirror grinding processing, inner hole surface roughness for Ra0.1, both ends curved surface roughness is as high as Ra0.025.Our technology to ensure the inner hole and into the outlet radian of natural transition, according to the aperture size to choose the radian of the scientific and reasonable, and maintain consistency, so as to ensure the smooth line.
2), the processing limit: d1 acuity 0.15 mm, thickness 0.10 mm or more.My company's tungsten steel needle (nozzle) are complete in specifications, can also be designed according to user's special requirements for customization.
carbide tungsten steel needle (nozzle) product advantages: inner hole and arc portion of grinding and polishing by coarse fine in ultrafine grinding, finally the simulation of the enameled wire winding process, to ensure its arc and roughness of surface, the last 100% full inspection through an electron microscope.
