Hollow Spindle Lathes

The HS series of lathes are heavy duty, simple CNC, hollow spindle lathes. Their design and manufacture is based on the accumulated experience of one of the world's leading heavy duty lathe manufacturing companies, and incorporates advanced design and manufacturing technologies.

These machines are used primarily for the internal and external threading of pipes, connectors, and other components for oilfield tubular goods, as well as other industries seeking to capitalize on the many advantages of a large spindle bore machine.

These unique machines are equipped with Fanuc's 0i-Mate TC CNC control system. One of the main advantages of these machines is the user-friendliness of the control system and the manual operation interface. These machines can be used in manual mode for OD/ID turning and facing operations, using only the spindle speed controls, hand wheels and joystick console. All types of complex shapes can be taught into the machine via the Fanuc Turn Mate software, which is integrated into the control system.
