Vervaardig van kwaliteit draad hoog, is elke deeltjie sny om 'n lengte oor gelyk aan sy deursnee. Indien nodig, word die deeltjies conditioning (afgerond) om die skerp hoeke wat tydens die snyproses te verwyder. Streng gehaltebeheer prosedures wat nodig is om in staat wees om te vervaardig gesny draad geskiet vergadering alle gemeenskaplike bedryf spesifikasies, sowel as baie individuele kliënt spesifikasies.
As-sny deeltjies is 'n doeltreffende skuur as gevolg van die skerp kante geskep in die snyproses. Maar as-sny geskiet is nie 'n gewenste geskiet peenen media. Die skerp kante, wat potensieel skadelik vir moegheid lewe, moet verwyder word in 'n proses genaamd "kondisionering".
Conditioning Sny Wire (CCW) geskiet word gewoonlik vervaardig in twee grade van kondisionering - Normale Conditioning wat die vereistes van SAEJ441 spesifikasie vorm aan, en die meer afgeronde Spesiale Conditioning wat voldoen aan die vereistes van Lugdiens spesifikasies soos AMS 2431.
Normale Conditioning

Spesiale Conditioning

Depending on application, various hardness ranges are available with cut wire media. Generally, the higher the hardness of the media, the lower the durability. However for shot peening applications, the shot used should be at least as hard as Almen strips or the part being peened, whichever is harder.Common Hardness Ranges in Carbon Steel Cut Wire Shot are: Blasting Applications – HRC 45-50; Shot Peening high strength parts such as carburized gears and springs HRC 55-60; and Shot Peening softer parts – HRC 50-55.
Versatility – One of the most important aspects of cut wire shot is its versatility. Cut Wire Shot can be made from many materials: Stainless Steels (Type 302, Type 304, Type 430 and others), 1070 Carbon steel of various hardness levels, Aluminum, Zinc and Nickel alloys. Size of media is not limited to the standards. Conditioning is offered in Standard degrees: As-cut, Normal and Special. Other degrees of Conditioning are, and can be supplied as well. Hardness ranges other than those discussed above can also be supplied.
