what do shot peening and shot blasting do?

What does shot peening do?
Peening causes the material in the surface zone to yield by literally shaking the metal grains into a more relaxed state. 

Thus, a thin layer of the surface is placed in uniform compression. This compressively-stressed "skin" counteracts tensile stresses and effectively prevents cracking.
What does shot blasting do?
Shot blsating directly converts electric motor energy into kinetic abrasive energy by rotating a turbine wheel. 
The capacity of each wheel goes from approximately 60 kg per minute up to 1200kg/min. With these large amounts of accelerated abrasive, wheelblast machines are used where big parts or large areas of parts have to be derusted, descaled, deburred, desanded or cleaned in some form.

Daily maintenance procedures for shot blasting machines

图片
1. Whether the fixing bolts on all the blasting machine and the blasting machine motor are loose, and it is found that the loosening is immediately tightened. 2. The wear of the wear-resistant parts and the shot blasting inside the shot blasting machine, and replace the worn parts in time. 3. Check the blades and replace them when they are half worn. 4. Check if the position of the directional sleeve pointer is correct.   5. Whether the shot blasting machine inspection door is closed. 6. Whether there is air leakage in the dust removal pipe, whether the filter bag in the dust collector is dusty or damaged. 7. There are no accumulations and other debris on the spiral shell and filter screen of the separator and remove it in time. 8. Check that the flow screen of the separator is uniform and forms a full curtain. 9. Is the electronically controlled pill gate closed? 10. Check whether the status of each limit switch and proximity switch is norma...

What is sand blasting machine ? Sand blasting   is the technique of mechanical surface cleaning which uses compressed air as its power shots the high speed abrasive sand stream to the surface of work piece. Due to the impacting and cutting effect of the abrasive sand, the work piece surface is completely cleaned. At the same time, the surface quality and mechanical performance is greatly improved. It is widely used in a variety of different industries with many diverse purposes. Sand blasting is also used in refurnishing sports part of car, motorcycle, electro mechanical device, etc. It helps in removing surface marks of metal/non-metal items, dumb face and fog treatment processing to enhance the product grade. Sand blasting   is also known as abrasive blasting. It is a process where fine granular sand is applied high pressure against a rough surface keeping in mind the end goal to smooth that surface out. In this process, the abrasive material is pushed,...

What are the different types of blasting?

Blasting is the techniques of removing dust, coating, polishing of different surfaces. There are many types of blasting process available according to the requirement like shot peening blasting. It puts small dents on the surface to give a finish where required and helps in wear resistance of the surface. The different types of blasting: Soda blasting Shot Grit Blasting Steel sandblasting Glass Bead blasting Bristle blasting Water blasting Air Blasting Sand abrasive blasting There is most common way of blasting and we called it sand blasting. It uses small grains of garnet for removing coating or polishing a surface. It is composed with the stream of compressed air that helps in acceleration of the particles while water blasting uses high pressure water guns to clean surfaces. They are available in both big and small sizes so they used in home as well as in industry also. Mayflay High Pressure Manual Abrasive Blast Cabinet Sandblasting Machine: ...
