Tungsten carbide cutting nozzle is a way of using high-pressure water cutting, it has block cutting speed, high cutting precision, long uninterrupted cutting, long life, predictability of a series of excellent performance. Widely used in metal, ceramics, stone, glass and cutting other materials. Tungsten carbide cutting nozzle working principle is to change the cross-section through the nozzle of the fan within the fan-shaped nozzle hole by shrinkage of the high-pressure section of the pressure of the water can be gathered together and converted into kinetic energy, and finally discharged to the outside in the form of a high pressure water jet material for cutting. Water cut is a cut way in the world's highest production capacity, it is superior to other processing techniques such as flame cutting, plasma processing, laser machining, edm, milling and processing car. Meanwhile, the water cutting does not produce harmful gases or liquids in the surface does not generate heat, it is truly multi-functional, high efficiency, cold cutting. Water cutting is a cold cutting state, the direct use of the kinetic energy applied to the abrasive water jet cutting metals to achieve the purpose of cutting, the cutting process without chemical change has no effect on the physical and chemical properties of material to be cut, no heat deformation, high narrow kerf, precision , cut smooth, clean pollution, etc., can be processed traditional processing and other processing methods can not be processed or difficult to machine materials, such as glass, ceramics, composite materials, reflective materials, chemical fiber, heat-sensitive materials.
