Tool spindles from SEMA Machine Tools

For drilling, milling, sawing and lathing!

SEMA components: tool spindle SE70

The externally driven SEMA tool spindles are characterised by the ability to sustain high radial or axial forces.

The precision spindle bearings used guarantee high spindle stiffness and maximum radial and axial run-out quality. SEMA tool spindles also feature a robust design.

SEMA tool spindles have lifetime lubrication, meaning less maintenance work and a minimised error risk. With the aid of sealing air, the tool spindles satisfy protection class IP64.
