Precision Components

SCHUMAG produces precision components with extremely narrow tolerances in the µm range.

We manufacture highly precise components according to customers' drawings quantities up to 50,000,000 annually – if required as custom-made unique item. Our specialty is small ground parts with a diameter of 0.3 mm to 80 mm.

We can reliably keep to roundness of up to 0.5 µm,
straightness of up to 0.5 µm and cylindricity of up to 0.7 µm.

To do this, we use for example grinding, hard turning, internal grinding or honing. By means of lapping and superfinishing we can ensure meeting requirements of up to Ra 0.01.

Diameter tolerances of up to 0.5 µm, length tolerances of up to 1 µm and flatness of up to 1 µm are challenges with which we are confronted on a daily basis. Our highly precise production processes ensure compliance with these narrowest tolerances.
