Horizontal Boring Mills for Large-Part CNC Machining

Horizontal boring mills, commonly called HBMs or CNC boring mills, are heavy-duty machine tools designed for machining large, heavy and complex components. Their horizontal spindle orientation and extendable boring spindle allow cutting tools to reach deep features and multiple surfaces of large workpieces.

Horizontal boring mills can perform boring, drilling, milling, tapping and related machining operations while reducing the number of setups required for large components.
