The shot peening process is being used extensively to produce better quality products in different industries including aerospace, aircraft, heavy equipment, automotive, energy industries. Shot peening is a cold metal working processing that is used over the metals for surface quality improvement. The metal parts come across several processes like milling, turning, severe grinding, drilling, welding, heat treatment, bending, forming etc that often leave tensile stress on the surface resulting in quick corrosion, cracking and short life properties. The shot peening machines improve the surface by eliminating the left out tensile stress.
The peening hammers were used even the centuries before but the process started drawing attention of large scale manufacturers only in late 20th century; and, more industries started to incorporate peening shot and strength controlled impacting processes. The leading shot peening machine manufacturers are doing focus on the variety and quality both; therefore, the users have more than before options today.
The more in demand shot peening machine models are table type with classifier, robotic peening shot machine, special purpose peening machine, peening shot for coil spring, leaf- spring peening machine, rods peening machine etc. The key buying parameters include direction & velocity of shots, quantity of shots, distribution of shots, required power, required space etc. In standard shot peening machine, the shots of higher hardness (2 HRC and above) are used. Indexing table type peening machine with classifier is designed to match with all the essentials in shot peening operations according to international standards; it has shot classifier, shot measurement device/ controller, shot speed & direction controller.
Parting Note:
All the reputed shot peening machines manufacturers offer on the site service under different models; therefore, looking into the maintenance aspect is also important, while comparing the proposals for shot peening machines.
