鍛件加工是金屬被施加壓力，經過過程塑性變形塑造哀求的形狀或得當的壓縮力的物件。這種力量典型的經過過程利用鐵錘或壓力來實現。鍛件過程制作了精致的顆粒結構，改進了金屬的物理屬性。在零部件的現實利用中，一個精確的籌劃能使顆粒流在主壓力的方向。需要每片都是一致的，沒有任何多孔性、多余空間、內含物或者其他的瑕疵。這種方法分娩的元件，強度和重量比有一個高的比率。這些元件通常被用在飛機結構中。鍛件的優點有可蔓延的長度、可壓縮的橫截面;可壓縮的長度、可蔓延的橫截面;可改變的長度、可改變的橫截面。清理的目的是去除套圈鍛件的毛刺和氧化鈹。有臥式滾筒清理和拋丸滾筒清理兩種：

　　Forging is an object in which the metal is applied to the pressure, and the plastic deformation is applied to shape the requested shape or the proper compressive force. This force typically passes through a hammer or pressure. The forging process makes a fine particle structure that improves the physical properties of the metal. In the practical use of parts, a precise planning allows the particles to flow in the direction of the main pressure. Each piece is required to be consistent without any porosity, excess space, inclusions, or other blemishes. This method of delivery has a high ratio of components, strength, and weight ratio. These elements are usually used in aircraft structures. Forgings have the advantages of a spread length, a compressible cross section, a compressible length, a spread cross section, a variable length, and a variable cross section. The purpose is to clean up and remove the burrs beryllium ring forging. There are two kinds of horizontal drum cleaning and shot blasting drum cleaning:

　　1.臥式滾筒清理：將尺寸大小不同的許多軸承套圈同時裝入以20～60r/min的轉速反轉展轉的臥式滾筒中遷徙改變和相互撞擊，使氧化鈹從鍛件表面寥落，同時還能把鍛件的毛刺和棱邊磨光，為了加速清理，有時在滾筒內放入一些廢鋼球。清理時間同樣平常為10～20min。此法大略易行，但清理質量差。

　　1. horizontal roller cleaning: many bearing rings of different sizes at the same time into 20 ~ 60r/min horizontal drum rotary speed of movement to change and mutual impact, the beryllium oxide from the forging surface scattered, while the edge burr and forging edge polishing, in order to speed up, sometimes in the drum into some scrap steel. The cleaning time is usually 10 to 20min. The method is simple, but the cleaning is poor.

　　2.拋丸滾筒清理：將鍛件裝入以低速(2.5～3r/min)遷徙改變的臥式密封滾筒內，粒度達0.8～1.2mm的鐵丸或鋼丸，從高速遷徙改變噴丸器葉片上拋出而沖到鍛件上，使氧化鈹因撞擊而寥落下來。鋼丸能自動循環，氧化鈹經過過程吸塵器吸出，鍛件撞擊噪聲小。

　　2. tumblast clean: the forging load at low speed (2.5 ~ 3r/min) horizontal movement to change the seal in the drum, the size of 0.8 ~ 1.2mm iron pellets or steel shot, from high-speed movement to change the blade and throw shot rushed to the forging, the beryllium oxide down due to impact and liaoluo. With automatic cycle, through the process of vacuum aspiration of beryllium oxide, the impact noise of small forgings.
