The SKJ vertical turning and open sided boring lathe is designed for use in very large machining and flexible production. The SKJ is a large super heavy-duty performance VTL from CKD BLANSKO.

The SKJ turning table incorporates a hydrostatic bearing for very heavy workpiece weight carrying up to 704,000 lbs. (320,000 kg). Along with the use of very large hydrostatic box ways and its single column, symmetrical head and large cross section ram design keeps it best in class for very large and heavy turning requirements.

The SKJ can also be equipped with a live milling and drilling spindle to further broaden its capabilities and if you add the “C plus C = Y” axis head it is the closest to one and done machine for large part turning and milling available.
