¡¡¡¡Burrs are ubiquitous "bad guys" in the processing of metal products. Whether it is punching, laser cutting, or plasma cutting, the processing process will form sharp edges and burrs on the surface of the workpiece. Especially during plasma cutting, slag (a mixture of oxides and metal residues) will stubbornly deposit on the edge of the workpiece. If there are burrs on the surface, it will increase the risk of personal injury, endanger product quality, affect equipment use, and even shorten the service life of the equipment. For example, burrs and falling metal powder on hydraulic valve bodies and pneumatic parts can cause severe turbulence or non laminar flow once they enter hydraulic or pneumatic systems, leading to filter or pipeline blockage. According to statistics, the cost of deburring in precision parts processing accounts for about 10% to 25%. If there are deep holes and grooves on precision parts, it will greatly increase the cost of deburring.

¡¡¡¡Deburring technology is developed for precision machining of different products and is suitable for deburring high-precision components such as aerospace, automotive locomotives, semiconductors, instruments and meters, engineering machinery, military industry, polymer materials, etc. It greatly improves production efficiency, reduces the probability of defective products entering the market, reduces the risk of manual injury, and enhances the production quality of enterprise products. Below is a brief introduction to high-pressure water deburring technology. High pressure water deburring uses a dedicated pump to pressurize water or water-soluble oil, and then sprays it out from a specially designed nozzle in a certain shape such as a fan or cone, generating huge impact energy to impact the parts and achieve the purpose of deburring. It can effectively remove burrs, chips, and oil impurities from cross holes, oblique holes, threaded holes, and blind holes inside the parts, especially suitable for various burrs formed after mechanical processing of complex parts. Due to the medium being water, it will not cause pollution to the environment. Suitable for deburring and cleaning various ductile iron, grey cast iron, powder metallurgy, cast aluminum alloy, zinc alloy, stainless steel parts such as automotive engines, transmissions, refrigeration compressors, marine and aircraft engines, military products, molds, etc.
