Firstly, the shot blasting machine throws casting sand, steel shot, etc. It is sprayed on the surface of workpiece by high-speed rotating shot blasting machine to achieve the effect of cleaning and surface treatment. The working principle of shot blasting machine is similar to throwing an object hard, and the thrown object is projected to the target surface through the action of external force. In addition, the shot blasting machine has high working efficiency and can quickly process large workpieces. Suitable for surface treatment of steel, aluminum alloy, stainless steel and other materials.
Shot peening machine sprays high-speed abrasive or spraying agent to the surface of workpiece through spraying device, and cleans the surface through impact and friction. The working principle of shot peening machine is similar to that of water gun or air gun, which uses high-speed fluid to clean the target surface. The work efficiency of shot peening machine is low, which is suitable for small workpieces or workpieces with special shapes. At the same time, the shot peening machine is also more suitable for processing workpieces with soft materials or unable to withstand high-speed impact.
Generally speaking, shot blasting machine is suitable for surface treatment of large workpieces and different materials, with high working efficiency; The invention is suitable for surface treatment of small workpieces and special shapes, and the working efficiency is low. According to different workpiece and processing requirements, appropriate equipment can be selected to meet the requirements.
