Horizontal machining center HBZ® TRUNNION®

Powerful 5-axis machining of a wide range of materials with an interference contour up to 1,700 mm


Today, modern production demands machining centers that are not just precise and productive but also flexible. The HBZ Trunnion horizontal machining centers cover the entire application spectrum up to an interference contour of 1,700 mm thanks to high speeds for HSC cutting of aluminum as well as high-torque motor spindles for heavy-duty cutting of titanium and steel. High travel speeds combined with the optimum designed spindle for the specific application ensure high precision for dynamic 5-axis machining.


The compact and intrinsically rigid machine design with double drive system and clamping on both sides of the NC rotary-swivel table as well as horizontal spindle combines all the advantages of horizontal machining with high performance on a compact footprint. The stable machine design guarantees highly-precise cutting.

The bavius machine concept offers unique benefits for your production!
