自动式抛丸机作为现代工业表面处理的核心设备，通过高速抛射弹丸实现工件表面的清理、强化及美化，其技术特性与实际应用效果呈现出鲜明的优劣对比。

　　As the core equipment for modern industrial surface treatment, the automatic shot blasting machine achieves cleaning, strengthening, and beautification of the workpiece surface through high-speed projectile ejection. Its technical characteristics and practical application effects show a clear comparison of advantages and disadvantages.

　　优势方面，自动化程度高是首要亮点。设备集成PLC控制系统，可预设抛丸强度、时间及弹丸流量参数，实现连续化作业，大幅减少人工干预，提升生产效率。以船舶制造为例，自动抛丸机单日处理钢板面积可达传统手工打磨的5倍以上。其表面处理质量稳定，弹丸以每秒50-80米的速度冲击工件，能有效去除氧化皮、焊渣及涂层，同时通过弹丸的冷作硬化作用提升工件疲劳强度，尤其适用于汽车齿轮、风电塔筒等高精度部件。此外，设备配备弹丸循环系统，通过螺旋输送器、分离器及斗式提升机实现95%以上的弹丸回收再利用，降低耗材成本。环保性能同样突出，全封闭舱体设计结合脉冲除尘装置，可将粉尘排放浓度控制在10mg/m³以下，符合国家环保标准。

　　In terms of advantages, a high degree of automation is the primary highlight. The equipment is integrated with a PLC control system, which can preset shot blasting intensity, time, and shot flow parameters to achieve continuous operation, greatly reducing manual intervention and improving production efficiency. Taking shipbuilding as an example, the daily processing area of steel plates by automatic shot blasting machines can reach more than 5 times that of traditional manual polishing. Its surface treatment quality is stable, and the projectile impacts the workpiece at a speed of 50-80 meters per second, effectively removing oxide scale, welding slag, and coatings. At the same time, the cold work hardening effect of the projectile improves the fatigue strength of the workpiece, especially suitable for high-precision components such as automotive gears and wind turbine towers. In addition, the equipment is equipped with a projectile circulation system, which achieves over 95% of projectile recycling and reuse through screw conveyors, separators, and bucket elevators, reducing consumable costs. The environmental performance is equally outstanding. The fully enclosed cabin design combined with pulse dust removal device can control the dust emission concentration at 10mg/m³ The following complies with national environmental standards.

　　局限性亦不容忽视。初始投资成本较高，一台中型自动抛丸机价格约在30-80万元之间，对于小微企业构成资金压力。设备对工件尺寸适应性有限，通常要求工件长度不超过3米、重量低于500公斤，超规格件需定制专用夹具或采用分段处理。维护要求严格，抛丸器叶片、定向套等易损件需每500小时更换，且弹丸材质选择直接影响处理效果，若使用含杂质弹丸将加速设备磨损。噪音控制难度较大，设备运行噪音通常在85-95分贝之间，需单独设置隔音机房或配备消音装置。

　　Limitations cannot be ignored either. The initial investment cost is relatively high, with a medium-sized automatic shot blasting machine priced between 300000 and 800000 yuan, which poses financial pressure for small and micro enterprises. The equipment has limited adaptability to the size of the workpiece, usually requiring a workpiece length of no more than 3 meters and a weight of less than 500 kilograms. For oversized parts, customized special fixtures or segmented processing are required. The maintenance requirements are strict, and vulnerable parts such as shot blasting blades and directional sleeves need to be replaced every 500 hours. The choice of shot material directly affects the treatment effect, and the use of impurity containing shot will accelerate equipment wear. The difficulty of noise control is relatively high, and the operating noise of equipment is usually between 85-95 decibels. It is necessary to set up a separate soundproof room or equip it with a silencing device.

　　自动式抛丸机以效率、质量及环保优势主导中高端制造领域，但其成本门槛、工件适应性及维护复杂性也限制了在小规模场景的普及。用户需根据产能需求、工件特性及环保要求综合评估，例如航空零部件企业可优先选用，而单件小批量加工场景则更适合手动或半自动设备。

　　Automatic shot blasting machines dominate the mid to high end manufacturing field with efficiency, quality, and environmental advantages, but their cost threshold, workpiece adaptability, and maintenance complexity also limit their popularity in small-scale scenarios. Users need to conduct a comprehensive evaluation based on production capacity requirements, workpiece characteristics, and environmental protection requirements. For example, aviation parts companies can give priority to using them, while single piece small batch processing scenarios are more suitable for manual or semi-automatic equipment.
