Center za globoko vrtanje in rezkanje

TBT Tiefbohrtechnik GmbH + Co BW250-T

The drilling method used by the deep hole drilling machine is single-lip drilling.

The BW250-T is a deep hole drilling and milling center featuring two separate spindles for deep hole drilling and milling operations. The machining units are equipped with a shared additional travel axis, allowing even small workpieces to be machined from four sides on the clamping table without repositioning.
