Grinding spindles


SLF’s grinding spindles are employed in grinding machines and machining centers for external and internal machining of various workpieces made of a wide range of materials (including metals, ceramic, special alloys, glass, etc.). They offer precision machining, quiet running, easy maintenance, long life, and robust design.
SLF’s grinding spindles make it possible to machine precise parts in the µm range at a surface roughness up to Ra 0.1 µm (polish-grinding).

Drive types:
We can deliver our grinding spindles with external drive, such as a precision grinding spindle for high speeds with a belt drive, as well as with an integrated or flanged motor.
High quality engineering – made in Germany.
