Wirtgen introduces precision grinding on X-Tier milling machine
At CONEXPO-CON/AGG 2026, Wirtgen revealed the W 210 XF, the first milling machine available with optional Wirtgen Precision Grinding (WPG) technology. In place of the milling drum, a WPG grinding shaft with more than 300 diamond grinding discs rapidly rotates to deliver a particularly high degree of surface evenness with a depth of 0 to 50 mm and width of 1,875 mm. Wirtgen says that WPG provides a smoother surface, lowering IRI. Operation of the W 210 XF with WPG is similar to traditional milling. The speed is slower, but the controls are the same, and slurry trucks are swapped instead of dump trucks.
