Hollow Spindles from A.MANNESMANN

Perfected in quality and accuracy - Spindles from A.MANNESMANN

Overview of A.MANNESMANN Hollow Spindles

As a specialist in geometrically sophisticated, long, slim machine components, we produce a wide range of spindles and spindle sets in over 200 versions with over 20 different spindle diameters with decades of expertise from our company.

Hollow Spindles in High-Precision Machining Units

Hollow spindles are high-precision machining units of a turning machine that are specifically designed for rotationally symmetrical machining with a wide variety of objectives. The working shaft designed as a hollow spindle supplies the chuck with bar material without affecting its dimensional stability. Hollow spindles are extremely powerful rolling or hydrostatically-supported machine assemblies whose production requires particular expertise.
