UNSPSC 23281700: Mechanical surface treatment machines

Machines that mechanically improve the surface properties of finished components.

UNSPSC 23281700 Mechanical surface treatment machines is a Class code that encompasses CNC equipment, wire electrical discharge machining systems, and specialized fabrication machinery being procured by state universities, community colleges, state transportation agencies, and county governments. Recent solicitations show state and local bodies acquiring precision metalworking equipment including CNC lathes, machining centers, wire EDM systems, and shearing machines, typically bundled with installation, training, and multi-year parts and service warranties. The issuing bodies include research universities (Texas A&M University System), state technical colleges (Texas State Technical College, Polk County Schools), a state transportation department (Texas Department of Transportation), a county environmental agency (Hillsborough County), and the State of California—representing a mix of higher-education, K–12, state infrastructure, and local government procurement. The code also captures parts and maintenance procurement for existing equipment, as evidenced by Hillsborough County's five-year maintenance and parts contract for composting equipment.

Recent activity concentrates in Texas, California, and Florida. Texas A&M University System has posted three ITBs since late June 2026 for CNC equipment, a CNC lathe and machining center, and machine shop and welding equipment—all responses due within weeks of posting and managed through the AggieBid platform. TxDOT has issued multiple IFBs for OEM replacement parts for Cincinnati Shear machines, with firm fixed pricing and delivery to its Austin production facility. Texas State Technical College is procuring Wire EDM machines with a one-year base term and four optional renewals through an RFP posted in March 2026 with a contract value exceeding $100,000 and a mandatory Subcontracting Plan requirement. The Polk County School Board issued a preliminary Request for Vendor Response in March 2026 for comprehensive CNC training solutions including desktop mills, lathes, simulators, tooling, and two-year warranty coverage. California has posted RFBs for a Water Table CNC Hypertherm Plasma Cutter and a shearing machine, both with March 2026 closing dates. Hillsborough County in Florida announced a sole-source award to Powerscreen of Florida for maintenance, repairs, and parts covering composting equipment over five years at an estimated total value of $1,992,824.18.
