Oil-air lubricated, 9,000 to 150,000 RPM
Internal Grinding & Milling Spindles
Engineered for high-frequency operations, our internal grinding spindles run from 9,000 to 150,000 RPM across 30 configurations. Precision angular contact bearings deliver thermal stability and low vibration, from PCB micro drilling through to engine block roughing. Several models are offered with two bearing and interface options so the spindle can drop into an existing machine without reworking the mount.
