World leaders in ultra precision machine systems since 1962.
We have built more than 75% of the world’s ultra precision machines for diamond turning (SPDT)

2. www.STERLINGINT.com Since 1962 you would have known us as …
PNEUMO PRECISION (1962)
RANK PNEUMO (1987)
PRECITECH … currently (Electro-Optics)
STERLING … currently (Ophthalmics)

3. All of the OPTOFORM and NANOFORM machine systems are built at the New Hampshire plant in the USA.

4. The light grey section of the factory is “temperature controlled” to facilitate precision machine construction.

5. Each machine is built in its own bay by a team of specialist engineers with different skill sets.

13. VARIFORM (OSCILLATING TOOL)
VARIFORMS have had more than a 95% global market share when it comes to manufacturing non-rotationally symmetrical surfaces in OPHTHALMICS.
Now the newer FTS-1000 is rapidly gaining market share.

14. NANOFORM 200

15. NANOFORM 250 Ultra

16. FTS-1000 – Fast Tool Servo (Oscillating Tool Technology).
The FTS-1000 is the most advanced technology for producing non-rotationally symmetrical surfaces of all kinds.
Its “stiffness”, combined with it’s range, makes for superior surface finishes and form.
