CNC BTA & GUN Drilling Machine

The STGB series is Column type BTA drilling machine with the functions of both GUN drilling and BTA drilling. It is designed for deep-hole drilling of large molds, hydraulic parts, construction machines, petrochemical equipments and other industrial machines. BTA drilling assures high precision holes and high productivity of more than 5 times of GUN drilling or 10 times of twist drilling.
Because a working table is stationary, drilling workpieces of any shape or heavy weight can be easily made.
