Crankshaft-Camshaft Grinding for Mass Production DU CNC

The Winona Van Norman DU Series Grinding Machines are engineered to deliver exceptional precision, productivity, and efficiency for demanding grinding applications. Designed with fully CNC-controlled movements, the DU Series combines advanced motion technology with rigid machine construction to produce superior surface finishes, maintain critical tolerances, and deliver highly repeatable results. Its intelligent automation makes it an ideal solution for high-precision engine rebuilding, industrial manufacturing, and production grinding environments.
At the core of the DU Series are closed-loop linear motors guided by high-precision external linear scales, providing exceptionally smooth, accurate, and repeatable motion throughout every grinding cycle. This advanced positioning system ensures precise control of machine movements, improves cycle times, and delivers consistent grinding performance across a wide range of applications. Fully CNC-controlled operation simplifies programming and setup while maximizing throughput and minimizing operator intervention.
The machine base is constructed from an advanced composite of steel and engineered concrete, carefully designed to optimize structural rigidity while controlling natural vibration frequencies. This innovative construction minimizes deformation, absorbs vibration, and maintains exceptional thermal stability, resulting in superior grinding accuracy and extended machine life. Combining advanced CNC technology, precision motion control, and an exceptionally rigid machine platform, the Winona Van Norman DU Series Grinding Machines provide the accuracy, durability, and long-term reliability professional manufacturers and machine shops depend on every day.
