TBM boring bars specifications

With the TBM Boring Bars, damaged, oval holes can be cut to size.

To be able to turn the holes back to the original size, there is an accessory with which the holes can be welded again. After welding, the original size can be returned.

The perpendicular guide surfaces can also be turned with an accessory.

There is a choice of various drive options.

Because the axial feed is adjustable, all roughnesses of the bore or the rectangular gasket surface can be achieved because versions with radial feed are also possible.

Today, the Boring Bar is available from standard axial feed only up to complete CNC controlled versions (also depending on the diameter).

The machines are delivered in one or more box (s) containing all the necessary accessories for processing the various diameters within the range.
