长期以大口径弹丸的称重、分级、标记等完全由人工来完成，工作效率低，重量标记质量不高，易出现差错，改变这种传统的落后生产方法，提高工作质量和效率，其唯一的出路在于生产过程的自动化。该文从弹丸称重、分级、印符等工序从生产工艺的机械结构和控制原理都作了详细的介绍。 Long-term large-caliber projectile weighing, grading, marking, etc. Completely by the manual to complete, low efficiency, weight marking quality is not high, prone to error, change this traditional backward production methods, improve work quality and efficiency, the only The way out is to automate the production process. This article from the projectile weighing, grading, printed symbols and other processes from the production process of the mechanical structure and control principles are described in detail.
