High Radial Rigidity Turning

Heavy-Duty CNC Lathe & Turning Spindles

What Is a CNC Lathe & Turning Spindles?

A CNC lathe spindle is a robust turning cartridge assembly engineered for CNC lathes, turning centers, and Swiss-type machines. Capable of continuous 6,000 RPM operation with <0.002 mm radial runout, it utilizes A2-4, A2-5, A2-6, and A2-8 spindle noses with high-load double-row roller bearings for heavy metal turning.

Engineered for maximum radial cutting load capacity and precision concentricity, TriQuench India lathe spindles power turning centers, Swiss-type automatic lathes, and special-purpose facing machines.
