Industry Applications

Application Scope

Engineered for large precision molds, long machine guideways, and heavy-duty components. The spacious 500 x 1000 mm (19.7" x 39.4") grinding capacity ensures exceptional flatness for oversized workpieces even at maximum travel.
Workpiece Materials

Ideal for various high-hardness pre-hardened steels, tool steels, cast iron, and exotic alloys. Powered by a standard 10HP high-torque spindle motor, it maintains superior dimensional accuracy and surface finish (Ra) during heavy stock removal.
Industry Applications

Widely utilized in automotive stamping dies, aerospace structures, large semiconductor bases, and precision machine tool manufacturing. Perfect for high-intensity industrial environments requiring high material removal rates and long-term stability.
