锻件加工是金属被施加压力，经过过程塑性变形塑造哀求的形状或得当的压缩力的物件。这种力量典型的经过过程利用铁锤或压力来实现。锻件过程制作了精致的颗粒结构，改进了金属的物理属性。在零部件的现实利用中，一个精确的筹划能使颗粒流在主压力的方向。需要每片都是一致的，没有任何多孔性、多余空间、内含物或者其他的瑕疵。这种方法分娩的元件，强度和重量比有一个高的比率。这些元件通常被用在飞机结构中。锻件的优点有可蔓延的长度、可压缩的横截面;可压缩的长度、可蔓延的横截面;可改变的长度、可改变的横截面。清理的目的是去除套圈锻件的毛刺和氧化铍。有卧式滚筒清理和抛丸滚筒清理两种：

　　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.卧式滚筒清理：将尺寸大小不同的许多轴承套圈同时装入以20～60r/min的转速反转展转的卧式滚筒中迁徙改变和相互撞击，使氧化铍从锻件表面寥落，同时还能把锻件的毛刺和棱边磨光，为了加速清理，有时在滚筒内放入一些废钢球。清理时间同样平常为10～20min。此法大略易行，但清理质量差。

　　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.抛丸滚筒清理：将锻件装入以低速(2.5～3r/min)迁徙改变的卧式密封滚筒内，粒度达0.8～1.2mm的铁丸或钢丸，从高速迁徙改变喷丸器叶片上抛出而冲到锻件上，使氧化铍因撞击而寥落下来。钢丸能自动循环，氧化铍经过过程吸尘器吸出，锻件撞击噪声小。

　　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.
