High-Precision CNC Grinding Spindles
What Is a CNC Grinding Spindles?
A CNC grinding spindle is an ultra-precision rotational shaft unit engineered for internal, external, cylindrical, and surface grinding operations. Operating at speeds up to 60,000 RPM with sub-0.002 mm runout accuracy, it features preloaded P4/P2 angular contact ceramic bearings for automotive, aerospace, and tool manufacturing.
Designed and manufactured in our precision facility in Ahmedabad, Gujarat, TriQuench India CNC grinding spindles deliver the highest rigidity, thermal stability, and vibration-free performance required for mirror-finish grinding.
