Maximum Performance Vertical Turning Center

Packed with industry leading technology and top quality components, the YAMA SEIKI GV-1 series vertical turning centers combine incredible power, strong constructions, and heavy duty cutting capabilities to bring you The Ultimate Machining Power®. These maximum performance machines will easily accomplish the demanding turning applications of today and tomorrow. With maximum turning diameter up to 1,800 mm ( 70.8" ), maximum weight load up to 8,000 kg ( 17,600 lb ), and available live tooling spindle & Cf-axis capabilities, turning, milling, contour milling and drilling applications may be completed in one single machine.

The high-rigidity vertical turning center construction, can easily overcome horizontal turning centers’ problems when machining large-diameter, heavy-weight and non-symmetrical work pieces.
Enclosed splashguards keep chips and coolant contained for a safe clean working environment.
Extra wide door width up to 2,100 mm ( 82.6" ) ( GV-1200 : 1,800 mm ( 70.8" ) ) enables large size work pieces to be loaded onto the work table with a crown block providing easy loading and unloading operations.
