毛刺，在塑膠件和金屬加工過程中無處不在。不論你采用多么高級的精密設備，它都會伴隨產品一起誕生。主要是材料的塑性變形而在被加工材料加工邊緣生成的一種多余的鐵屑，尤其是延展性或者韌性較好的材質，特別容易出現毛刺。

　　Burrs are ubiquitous in plastic parts and metal processing. No matter how advanced precision equipment you use, it will be born with the product. It is mainly a type of excess iron filings generated at the processing edge of the processed material due to plastic deformation of the material, especially for materials with good ductility or toughness, which are particularly prone to burrs.

　　毛刺類型主要有飛邊毛刺、尖角毛刺、飛濺等不符合產品設計要求的一種突出的多余的金屬殘余部分。對于這個問題，到目前為止還沒有一種有效的方法能夠在生產過程中將其杜絕，所以為了保證產品的設計要求，工程師們只有在后道的去除方面下功夫，到目前為止針對不同產品不同的去除毛刺的方法和設備已經有很多種了。

　　The types of burrs mainly include flying edge burrs, sharp corner burrs, splashes, and other protruding excess metal residues that do not meet product design requirements. So far, there is no effective method to eliminate this problem in the production process. Therefore, in order to ensure the design requirements of the product, engineers can only focus on removing burrs in the later stage. So far, there are many different methods and equipment for removing burrs for different products.

　　一般情況下， 可將去除毛刺的方法分為四大類：

　　In general, the methods of removing burrs can be divided into four categories:

　　1. 粗級（硬接觸）：屬于這一類的有切削、磨削、銼刀及刮刀加工等。

　　1. Coarse grade (hard contact): This category includes cutting, grinding, filing, and scraping.

　　2. 普通級（柔軟接觸）：屬于這一類的有砂帶磨、研磨、彈性砂輪磨削及拋光等。

　　2. Ordinary level (soft contact): This category includes sanding, grinding, elastic grinding wheel grinding, and polishing.

　　3. 精密級（柔性接觸）：屬于這一類的有沖洗加工、電化學加工、電解磨削及滾動加工等。

　　3. Precision grade (flexible contact): This category includes flushing machining, electrochemical machining, electrolytic grinding, and rolling machining.

　　4. 超精密級（精密接觸）：屬于這一類的有磨粒流去毛刺、磁力研磨去毛刺、電解去毛刺、熱能去毛刺以及密鐳強力超聲波去毛刺等， 這類去毛刺方法可獲得足夠的零件加工精度。

　　4. Ultra precision level (precision contact): This category includes abrasive flow deburring, magnetic grinding deburring, electrolytic deburring, thermal deburring, and strong ultrasonic deburring with radium. These deburring methods can achieve sufficient machining accuracy for parts.

　　當我們在選擇去毛刺方法時，要考慮多方面的因素，例如零件材料特性、結構形狀、尺寸的大小和精密程度，尤其要注意表面粗糙度、尺寸公差、變形以及殘余應力等變化。

　　When choosing a deburring method, we need to consider various factors such as the material properties of the parts, structural shape, size and precision, especially paying attention to changes in surface roughness, dimensional tolerances, deformation, and residual stress.

　　可以用高壓去毛刺清洗機

　　High pressure deburring and cleaning machine can be used

　　高壓去毛刺清洗機借助高壓水流的沖擊力與特殊的流場設計，實現對工件表面毛刺的清除和污漬的清洗，其核心原理是通過能量集中的流體作用，高效處理傳統手工難以觸及的細微毛刺和復雜結構區域。

　　The high-pressure deburring cleaning machine utilizes the impact force of high-pressure water flow and special flow field design to remove burrs and stains on the surface of workpieces. Its core principle is to efficiently process fine burrs and complex structural areas that are difficult to reach by traditional manual labor through the concentrated fluid action of energy.

　　設備的核心動力來自高壓泵組，它能將普通自來水或專用清洗液加壓至數十到數百兆帕，形成高壓水流。水流經特制噴嘴噴出時，速度可達每秒數十米，這種高速流體具有強大的動能，接觸工件表面的毛刺時，會產生瞬間沖擊力，使毛刺在超過其承受強度的力的作用下斷裂脫落。噴嘴的設計是關鍵，根據工件的形狀和毛刺分布，可選用扇形、錐形或旋轉式噴嘴，扇形噴嘴適合大面積平面去毛刺，錐形噴嘴則能精準作用于孔道、凹槽等狹窄部位，旋轉式噴嘴通過水流的旋轉形成螺旋狀沖擊力，提升復雜曲面的處理效果。

　　The core power of the equipment comes from the high-pressure pump unit, which can pressurize ordinary tap water or specialized cleaning solution to tens to hundreds of megapascals, forming a high-pressure water flow. When water is sprayed out through a specially designed nozzle, its speed can reach tens of meters per second. This high-speed fluid has strong kinetic energy, and when it comes into contact with burrs on the surface of the workpiece, it will generate instantaneous impact force, causing the burrs to break and fall off under the force exceeding their bearing strength. The design of the nozzle is crucial. Depending on the shape and burr distribution of the workpiece, fan-shaped, conical, or rotary nozzles can be selected. Fan shaped nozzles are suitable for large-scale flat deburring, while conical nozzles can accurately act on narrow areas such as ducts and grooves. Rotary nozzles generate a spiral impact force through the rotation of water flow, improving the processing effect of complex surfaces.

　　除了沖擊力，水流的空化效應也輔助增強去毛刺效果。當高壓水流與工件表面接觸時，水流速度驟變會產生微小氣泡，這些氣泡在高壓環境下迅速破裂，釋放出局部高壓能量，對毛刺形成二次沖擊，尤其對細小毛刺（如直徑小于 0.1 毫米）的清除效果顯著。這種空化作用還能滲透到工件的縫隙和盲孔中，將藏匿其中的碎屑和油污帶出，實現清洗與去毛刺的同步進行。

　　In addition to the impact force, the cavitation effect of water flow also assists in enhancing the deburring effect. When high-pressure water comes into contact with the surface of the workpiece, a sudden change in water flow velocity will produce tiny bubbles. These bubbles quickly rupture in high-pressure environments, releasing local high-pressure energy and causing secondary impact on burrs, especially for small burrs (such as those with a diameter less than 0.1 millimeters), with significant removal effects. This cavitation effect can also penetrate into the gaps and blind holes of the workpiece, bringing out the hidden debris and oil stains, achieving synchronous cleaning and deburring.
