PURPOSE: A vertical BTA drilling machine is provided to reduce the machining time and to be able to machine plural holes at the same time by mounting a pair of spindle assemblies and fixing the machining object perpendicular to the plane of a rotary table assembly. CONSTITUTION: A vertical BTA drilling machine is composed of a rotary table assembly(11), a pair of spindle assemblies(12a,12b), and a C-shaft assembly. The rotary table assembly fixes the machining object. A BTA drill machining the machining object is mounted on the spindle assembly. The C-shaft assembly adjusts the machining angle of a tool. The machining object is fixed perpendicular to the plane of the rotary table assembly.
