Crankshaft Grinding Machine CGX270-2000

The Winona Van Norman CGX Crankshaft Grinder is an entry-level precision grinding machine engineered for engine rebuilding, repair facilities, and low-volume crankshaft production. Designed to deliver exceptional accuracy and repeatability, the CGX combines advanced CNC technology with a rigid machine platform to produce precise journal finishes while maintaining critical dimensional tolerances. Its compact footprint and user-friendly operation make it an ideal solution for professional machine shops seeking dependable crankshaft grinding performance without sacrificing precision.
At the heart of the CGX is a PLC-controlled system with X- and Z-axis movements driven by precision ballscrews, linear guideways, and high-resolution linear encoders to ensure smooth, accurate positioning throughout every grinding cycle. A centralized automatic lubrication system promotes long-term reliability while reducing maintenance requirements, and the automatic wheel dressing cycle with automatic wheel positioning maintains consistent grinding accuracy and surface finish quality. A fully automatic wheel balancing system, integrated vibration monitoring, and a 3D touch probe mounted on the grinding wheel head further enhance precision by simplifying wheel setup and optimizing grinding performance.
Designed for productivity and long-term durability, the Winona Van Norman CGX features a generous 2,550 mm Z-axis travel, 315 mm X-axis travel, and a 710 mm grinding wheel, providing the versatility to accommodate a wide range of crankshaft applications. Combining intelligent automation, precision engineering, and rugged construction, the CGX delivers the accuracy, repeatability, and reliable performance professional engine rebuilding and manufacturing facilities depend on every day.
