影响抛(喷)丸强度的主要因素有：
(1)抛丸大小：抛丸越大，冲击动能越大，抛丸强度也越大，但抛丸的覆盖率降低。因此，在保证抛丸强度的同时，应尽量选用较小的抛丸。此外，喷丸尺寸还受零件形状限制。当零件上有沟槽时，抛丸直径应小于沟槽内圆半径的一半。抛丸粒度常在6—50目之间选用。
(2)抛丸的硬度：当抛丸硬度比零件硬度高时，它的硬度值的变化不影响抛丸强度；当抛丸比零件软时，若抛丸硬度值降低，抛丸强度也降低。
(3)抛丸速度：抛丸速度增加时，抛丸强度也增加，但速度过高时，抛丸破损量增加。
(4)喷射角度：抛丸射流与待喷表面垂直时，抛丸强度高，因此一般都应保持在这种状态下进行抛丸处理。若受零件的形状限制，必须用小角度喷丸时，应适当加大喷丸尺寸与速度。
(5)抛丸的破碎量 ：抛丸破片的动能低，破碎了的抛丸越多，喷丸强度降低，而且不规则的碎丸会划伤零件表面，因此应经常清除碎丸，保证喷丸完整率大于85%。抛丸设备基本相同，只需采用一些辅助装置来更严格的控制抛丸过程。

Effect of toss(spray)pill strength are the main factors:
(1) size: the larger shot blasting, shot blasting impact kinetic energy is big, but also higher strength, but the coverage rate reduce blasting. Therefore, in ensuring blasting strength while, should try to use smaller shot. In addition, shot size is also affected by the shape of parts limited. When the parts on which a groove, shot blasting diameter should be less than half of the trench within a circle of radius. Shot size in 6-50 between the head selection.
(2) when the shot blasting hardness hardness than the hardness of parts is high, its hardness change does not affect the impact strength; when the shot than parts of soft, if shot hardness value decreased, shot blasting strength also decreases.
(3) shot blasting velocity speed increases, shot blasting strength also increased, but the speed is too high, shot blasting damage increase.
(4) shot blasting jet and spray angle perpendicular to the surface to be sprayed, shot blasting intensity is highest, which generally should be maintained in this state for shot blasting. If the restrictions on the shape of parts, must use the small angle of shot peening, should be appropriately increased the size and speed of shot peening.
(5) a shot blasting crushing amount: shot blasting fragments of the kinetic energy is low, broken shot more, shot peening strength is reduced, and irregular broken pill will scratch the surface, therefore should always clear crushed pill, ensure the integrity rate of greater than 85% shot peening. Shot blasting equipment is basically the same, only need to use assistive devices to more strictly controlled blasting process.
