ISO 5.5F

The model ISO 5.5F spindle was originally designed to meet the demanding requirements of the ultra-precision single point diamond turning industry. The application of the ISO 5.5F has grown to include conventional flycutting, raster flycutting, free-form surface generation, HDD servo track writing, DVD mastering, and metrology in vacuum environments. The Spindle’s central stiffness and extremely low error motion while being driven with a powerful brushless-DC motor can not be matched by any other spindle manufacturer in the world.

See a few example parts machined with the ISO 5.5F spindle.
