Cut wire shot and cast steel shot are two commonly used abrasives in shot blasting machines. In some cases, they can replace each other or be mixed in a certain proportion. The following are the differences and characteristics between them.

First, cut wire shot is cut from raw wire or cooked wire and is cylindrical. The model refers to the diameter of the wire cutting particles, not the length of the cut. This production is relatively simple, so the price is relatively cheap. The advantages of cut wire shot are low price and long service life, but the roughness of the cleaned workpiece is high, which is not suitable for processing some high-precision workpieces. The shape of cut wire shot is irregular, with less wear in the early stage, and powder can be exploded in the later stage. They cannot form a suitable proportion of small and large particles. Therefore, the shot blasting coverage is low, and the cleaning efficiency is not as high as that of steel shot.

Cast steel shot is first a round shot, which is a sphere. His production process is more complicated and the cost is relatively high. As a result, its price is more expensive than cut wire shot and its service life is shorter than cut wire shot. However, the surface of the workpiece he throws is smooth, and the surface roughness requirement of the workpiece can only be cast steel shot. The roundness of cast steel shot is very good. After hitting the ball, the stress points of the workpiece are regular, the stress is uniform, the hardness is moderate, and the resilience is good. The surface of the workpiece cleaned with steel shot is delicate and bright, the surface quality is good, and the grade of the workpiece is improved.

In summary, the cost-effectiveness of steel shot is less than that of wire cut shot.
