Description
Multi-Diameter CNC Grinding Flexibility

The Okamoto OGM-NCIII Series is capable of grinding up to ten different diameters within a single programmed cycle sequence. This capability significantly reduces setup time while maintaining consistent dimensional accuracy. As a result, productivity increases without sacrificing precision across complex component profiles. The flexible cycle configuration allows manufacturers to optimize throughput in both short- and long-run production environments.

 

Rigid Construction and Structural Stability

The OGM-NCIII Series features a rigid machine design engineered for optimal grinding performance. Its T-shaped main casting enhances structural integrity and load distribution. In addition, the fully supported table minimizes deflection and ensures vibration-free operation. This stability is critical for maintaining tight tolerances and achieving high-quality surface finishes during precision grinding applications.

 

Precision Slideways and Spindle Performance

Double V slideways provide exceptional straightness and smooth axis travel throughout the grinding process. Moreover, the extremely rigid spindle design delivers the stability required for high-precision cylindrical grinding. Together, these features ensure consistent geometry, repeatable accuracy, and superior surface integrity across demanding workloads. The Okamoto OGM-NCIII Series reflects advanced CNC cylindrical grinding technology engineered for automotive components, aerospace parts, and intricate precision tooling. It delivers a balanced combination of precision, flexibility, and operational efficiency for modern manufacturing environments.
