External Grinding Spindles
External grinding spindles are precision-engineered rotary spindles used for OD grinding (outer diameter) and surface grinding of components. These spindles ensure high RPM, low runout, and consistent grinding quality, whether you’re using a CNC grinding machine or a manual surface grinder.
Our external grinding spindles are available in belt-driven or motorized formats, and come with multiple mounting, clamping, and cooling options.
