UNSPSC 23281702: Shot peening machine

Shot peening machines repeatedly hit the workpiece surface with a large number of cast steel, glass, or ceramic shot (small balls), making overlapping indentations on the surface. This process improves the fatigue life of the component and is used extensively on shafts, gears, springs, oil-well drilling equipment, and jet-engine parts.

UNSPSC 23281702 Shot peening machine, a Commodity code, does not see active state and local procurement under its nominal scope. Recent opportunities tagged with this code consist primarily of CNC machining equipment, wire electrical discharge machines, shearing machines, and related production-floor tooling solicitations. The mismatch between the code name (shot peening machine) and the actual work being bought suggests either miscategorization in state and local agency procurement systems or that shot peening is bundled within broader machine-tool procurements without separate specification. The issuing bodies across the identified opportunities are higher-education institutions (Texas A&M University System, Texas State Technical College, Polk County School Board), state agencies (Texas Department of Transportation, California), and one county utility authority (Hillsborough County). Educational institutions dominate the recent activity, particularly Texas A&M, which has posted multiple ITBs for CNC equipment, machining centers, machine shop equipment, and wire EDM systems within the past two months.

Recent opportunities cluster in Texas and California. Texas A&M University System issued ITBs for a CNC lathe and machining center (due July 23, 2026), machine shop and fabrication equipment (due July 15, 2026), and general CNC equipment (due July 13, 2026), all through the AggieBid platform; Texas State Technical College is procuring Wire EDM machines and transformers under RFP-315 (due March 11, 2026) with a contract value exceeding $100,000 and subcontracting plan requirements; and Texas Department of Transportation has solicited OEM replacement parts for Cincinnati Shear machines at its Austin Production Shop across multiple ITBs. California issued RFBs for a water table CNC hypertherm plasma cutter (due June 11, 2026) and a shearing machine (due March 10, 2026). Hillsborough County in Florida posted a sole-source notice of intent for composting equipment maintenance ($1,992,824.18 over five years), and Sourcewell (Minnesota) issued a cooperative purchasing RFP for law enforcement equipment on behalf of participating entities including Washington-state counties. The code shows no dedicated shot peening solicitations among recent state and local activity, suggesting the category is either dormant or systematically miscoded in these jurisdictions.
