Sliding head lathes

SP-32 Sliding Head Lathe from Star is the latest addition to Star’s SP Series of sliding head lathes, developed to deliver outstanding versatility, accuracy and performance for applications up to 32mm (35mm optional) bar diameter.

It features Step Cycle Pro chip-breaking technology, high-speed processing at 35m/min, and guide bush/non-guide bush capability. It can achieve a main spindle speed of 7,000 rpm/power 7.5Kw, and a sub spindle speed of 7,000 rpm/power 3.7Kw. Other features include thermal displacement correction technology, built-in sensors on main/ sub for improved indexing accuracy, and an ECO Mode standby power saving function.

The machine incorporates a zero-shaped tool post with a 6-station platen on the front and a 6-spindle cross-drilling unit at the rear. Four of the cross-drilling unit’s spindles are cartridge-type positions where a wide variety of tool units can be mounted to suit complex applications. In addition, a 5-spindle sleeve holder (drilling arm) is provided with three positions at 22mm and two positions at 32mm diameter.

The backworking platen is specified with a 5-spindle tool post with driven tool capability as standard, enabling up to four rotating tools for efficient (overlapped) back machining and reduced cycle times.

Incorporating various technologies to minimize heat generation, the SP-32 includes Star’s innovative thermal displacement correction technology to optimize accuracy, stability and machining performance.

The machine is compatible with the latest software developments including Step Cycle Pro chip-breaking technology and Star’s innovative new ECO mode, an energy saving function that saves power during machine standby.
