工件上的毛刺危害有多大？

　　How harmful are burrs on workpieces?

　　毛刺，在金屬制品加工過程中無處不在的“壞小子”，無論是沖孔、激光切割還是等離子切割，加工工序都會在工件表面形成鋒利的邊緣和毛刺，特別是等離子切割時，熔渣（氧化物和金屬殘留物的混合物）會頑固沉積在零件邊緣。表面若存在毛刺會增加人員受傷的風險，危及產品質量、影響設備使用甚至縮短設備的使用壽命。比如液壓閥體和氣動零件上的毛刺和脫落的金屬粉末，一旦進入液壓或風動系統(tǒng)中將會產生嚴重的紊流或非層流，導致過濾器或管道堵塞。據統(tǒng)計，在精密零件加工中，去毛刺的成本約占10%~25%，若精密零件上有深孔和切槽，將使去毛刺成本大大增加。

　　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.

　　高壓水去毛刺技術特點

　　Characteristics of high-pressure water deburring technology

　　去毛刺技術為不同制品的精密加工而生，適用于航天航空、汽車機車、半導體、儀器儀表、工程機械、軍工、高分子材料等高精度要求的元件除毛刺，大幅提高生產效率，降低不良品流入市場的概率，降低人工受傷的風險，提升企業(yè)產品生產質量。下面為大家簡單介紹高壓水去毛刺技術高壓水去毛刺是利用專用泵把水或水溶性油的水加壓后，從特殊設計的噴嘴以一定的形狀如扇形、錐形等噴射出去，產生巨大的沖擊能量對零件進行沖擊，達到去除毛刺的目的。可有效去除零件內部的交叉孔、斜孔、螺紋孔以及盲孔的毛刺、切屑及油污雜質，特別適用于復雜零件在機械加工后形成的多種毛刺。由于介質是水，不會對環(huán)境造成污染。適用于汽車發(fā)動機、變速箱、制冷壓縮機、船舶、飛機發(fā)動機、軍工產品、模具等各種球墨鑄鐵、灰口鑄鐵、粉末冶金、鑄造鋁合金、鋅合金、不銹鋼零件的去毛刺清洗。

　　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.
