Main differences between shot blasting and shot peening:

• The angle of attack, the abrasive (spheres) release position against the workpiece.
• The volume of abrasive launched.
• Abrasive launching speed.
• Abrasive rating (size, roundness).


Benefits of shot peening machine

Forming (deforming or straightening workpieces, also known as peen forming).

Improves the resistance to mechanical and thermal fatigues.
Improves the corrosion and friction resistance.
• Allows reducing the size and weight without compromising the mechanical resistance.
Eliminates the directional risk of machining or micro-cracks, inhibiting crack propagation.


Shot peening machine applications

Automotive industry: springs, gears, torsion bars, rods, crankshafts, axles and suspension arms.
Metalworking industry: cutting tools, stamping, forging (mostly cold).

Aerospace industry: which is the one that mainly uses shot peening, lots of the components of aircraft are treated with shot peening, including various components of turbines, structural and landing gear.


We can provide not only the equipment but a complete solution for many different applications of shot peening. Beyond producing shot peening equipment systems, by blast wheel, pressure, suction, wet (in cases where severe restrictions on roughness exist) or a combination of two or more of these systems are equipped with the most efficient systems to monitor all process variables.


CMV® has the means to specify the parameters of shot peening and train operators, create process routines, inspection plans, and train shot peening inspectors. The shot peening equipment we produce meets the process, or productivity needs an integrated system with CN, CNC or robotics, both in handling the parts treated as for movement of the nozzles or shot peening guns.
