Conventional Crankshaft Grinding Machine CGA

Category: Conventional Crankshaft Grinding

The Winona Van Norman CGA Crankshaft Grinder is engineered to deliver exceptional precision, efficiency, and reliability through an advanced moving-wheelhead design. Unlike traditional crankshaft grinders, the CGA moves the grinding head while the crankshaft remains securely clamped between a fixed headstock and an air-assisted tailstock. This innovative configuration reduces the overall machine footprint while maintaining exceptional grinding accuracy, making it an ideal solution for engine rebuilding, remanufacturing, and precision crankshaft production.

At the heart of the CGA is a precision grinding wheel carriage that travels smoothly along the X and Z axes using high-accuracy ballscrews and hardened linear guideways. This advanced motion system provides precise wheel positioning, superior surface finishes, and repeatable dimensional accuracy throughout every grinding cycle. The machine base is constructed from COMPOSITAL®, an innovative resin-granite composite reinforced with a welded steel structure that significantly reduces vibration, improves thermal stability, and increases overall machine rigidity for consistently accurate grinding performance.

Designed for maximum productivity and operator convenience, the CGA features an air-suspension tailstock that glides effortlessly into position without metal-to-metal contact between the tailstock base and the table surface. This design minimizes wear, simplifies setup, and ensures smooth, reliable workpiece positioning throughout the grinding process. Combining innovative engineering, advanced materials, and precision motion control, the Winona Van Norman CGA Crankshaft Grinder delivers the accuracy, durability, and long-term performance professional machine shops and manufacturers depend on every day.
