Tungsten carbide nozzle is to use precision machinery and carbide materials (superhard alloy) and elaboration. The bending curvature of 2300 n/mm, degree of hardness of HRA90. When machining carbide nozzle, we achieve the precision grinding and surface treatment, realize the hole roughness for Ra0.1 and R, roughness on both ends for Ra0.025.
At the entrance of the two There is a radius of curvature of the scientific design. This design can ensure the thread to go through. Due to the overall materials processing, there is no elevation in drilling, compared with the ruby nozzle, easy to bend and jams has improved. Tungsten carbide nozzle is made up of hot straight hole and QiuKong of hot pressing sintering. Because of its hardness, low density and excellent wear resistance and corrosion resistance, tungsten carbide nozzle has been widely used in sand blasting and shot peening equipment, guarantee the products in the best air and abrasive medium long time use.Tungsten carbide thread slot nozzle cross wrench for PDC.
tungsten carbide welded nozzle cross wrench series quality control
all raw material are tested in terms of density, hardness and T.R.S before use.
There are strict inspection on process and final products.
every batch of product can be traced.
