What is Shot Peening?
A process widely used in manufacturing mechanical parts, shot peening is known for hardening the surface of metal components to prepare them for use. As the life of these parts will often be repetitive & stressful, fractures and breaks are liable. Shot peening is used to reinforce the surface of the metal, strengthening the fatigue resistance.
Shot peening is a cold work process when a media in the form of small circular objects is shot at a metal subject with enough force that results in a small dent to the surface. The media can be metal, glass or ceramic, with multiple of the small ball-bearing sized objects used to create multiple tiny indentations to the surface. As each impact indents the surface, the directly targeted area will cave in with surrounding (softer) material pushing to the sides into the compression range. Because lots of media is aimed at the area, the compression range will be repetitively hit causing the overall area to be compressed & encased in a compressively stressed layer.
Benefits of Shot Peening
- Strengthens the surface of the metal.
- Increase fatigue resistance, increasing the functional longevity of the item.
- Reduces the possibility of cracking.
- Remove unwanted tension in the material (from previous processes).
- Fills out surface pores.
- Produces a ‘pebbly’ surface which is desirable with certain components.
- Dislodge small debris.
Due to the compression, shot peening can marginally distort the surface of the metal which could be problematic for parts that require precision. For these circumstances particle shot peening would be used, as it uses a smaller medium that could be more carefully controlled.
Who Uses Shot Peening?
Commonly used in the medical, aerospace & automotive industries, shot peening is used for an extensive range of items such as gears, springs, rods, crankshafts, pistons, drill bits, propeller shafts, turbine blades, epidural gear & much more.
Machines for Application
When it comes to shot peening there are two types of machines that can achieve the desired effect, air blasting machines & centrifugal wheelblast machines. As each has its advantages, it is common that specific components are more suitable to be hardened by one machine rather than the other.
Air Blasting
Utilizing compressed air to shoot media at the surface, air blasting machines are precise and efficient, firing the media via a nozzle. Requiring to be connected to an air supply, these machines can accurately control the speed the media is fired at. Their design can vary, frequently seen as self-contained blast rooms, abrasive blast cabinets or portable equipment, potentially containing multiple nozzle guns for increased coverage.
Centrifugal Wheelblast
To shoot its media and implied by its name wheelblast, these machines use a high-speed paddle wheel to fire their media. These machines are often called airless blasting machines to differentiate the pending technology from air blast machinery. Able to fire at a speedy rate, the movement of the wheel is directly driven or belt driven. All this takes place inside a closed chamber, the centrifugal force allowing for even coverage to the surface of all the parts inside.
Comparison
Upon comparison, both these machines are very efficient at shot peening so deciding on which to use for different components is dependent on their strengths.
