Since entering the plant in 1987, it has been micro-shaping gunpowder for missile solid fuel engines. In the gunpowder, a slight accidentally rub the spark, it may cause a burning explosion. At present, gunpowder shaping is a problem all over the world and can not be completely replaced by a machine. Under the knife force, completely depends on the workers themselves to determine whether the drug face accuracy, directly determines the missile’s precision range. 0.5 mm is a solid engineered face powder
