Surface texture can unlock the key to higher performance. A popular secondary operation to Accelerated Surface Finishing / micro polishing can be micro peening. 


Micro peening can be confused with standard bead blasting or a glass bead finish quite easily if you are looking at the visuals only. Glass bead produces a beautiful satin finish, however, can lack the necessary requirements to modify the mechanical properties of the substrate you are blasting.


A true micro peened surface will have a uniform dimpled appearance due to true elastically deformed surface material

EQUIPMENT plays a major role in the effectiveness of this process and blast machines are continuously neglected and unmaintained because of how many wear-parts are actually in them. Filters - nozzles - jets - hoses - metering valves - pressure gauges - 4way valves - the list goes on and on. If the machine does not have a reclamation and dust collection system, it is nearly impossible to maintain proper media condition to effectively reproduce this finish.

Direct Pressure vs. Suction 


Most common blast cabinets on the market are consumer grade suction blast cabinets. Suction cabinets rely on the principal of venturi and are hindered with how much kinetic energy each blast particle can deliver. When compared to an industrial direct pressure machine, Almen strip testing shows 4x the energy per particle can be delivered. Because this process relies on the ability for surface deformation - most hardened steel components will not have a true elastically deformed surface when processed in a suction blast machine.
