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.

The ISO 5.5E motorization option.
B13-25 brushless dc motor
4.0 N·m continuous torque to 9,200 rpm with MCS AX-2000 drive apmlifier and a 10,000 rpm max. speed.
B12-25 vs. B13-25 brushless dc motor comparison.
The B12-25 motor provides more continuous torque at slower speeds (less that 4,000 rpm) and lower radial synchronous error motion (the B12-25 typically has less than 1.0 nm of motor pole print thru) vs. the B13-25 motor (typically 2.0 — 8.0 nm of motor pole print thru). Both motors are of a 12 pole design.
