Car-shot blasting machine is the use of steel balls sent to the high-speed rotation of the disc, using centrifugal force, so that high-speed crash parts thrown Abrasive surface, to achieve the purpose of polishing, shot blasting machine can produce parts of the surface stress, and no silicon powder, environmental pollution. 
 Car-shot blasting machine is mainly used as follows: 

 ① shot blasting machines to produce parts of the surface compressive stress can increase their fatigue strength and tensile stress corrosion; 

 ② Abrator twisted thin-walled parts can be corrected; 

 ③ shot blasting machine process instead of a general cold and hot forming process, the large thin-walled aluminum parts forming, not only can avoid the parts surface residual tensile stress, and obtain favorable compressive stress on the parts. It should be noted: shot blasting machine processed part temperature not too high, otherwise stress will disappear at high temperatures, thus losing the desired effect. They used the temperature determined by the material parts, iron and steel parts for the average is about 260-290 ℃, aluminum parts only 170 ℃.
