C-axis Position Control of Work Spindle  

One of our most diverse and popular options which allows continuous path contouring using X, Z, & C axes. This option is used for single point diamond machining of toric & freeform surfaces via Nanotech's "Slow-Slide-Servo" (S³) machining process. Note: S³ machining requires Nanotech's NanoCAM4^3T or suitable software for generation of X, Z, C file formats.

Oil Hydrostatic Rotary B-axis

Fully constrained oil hydrostatic rotary bearing option. For use with the Nanotech 450UPL or 650FG machines, this axis utilizes a direct drive brushless DC rotary motor and high resolution encoder. The B-axis has a positioning accuracy of +/- 1.0 arc second and feedback resolution of 0.005 arc seconds. Radial and axial motion errors are guaranteed to ≤ 100nm. Includes pneumatic / mechanical brake.

Nanotech Fast Tool Servo (NFTS-6000^v2)

The newest version of our advanced closed loop fast tool servo accessory with 6mm of total stroke and micro height adjustment stage!  Voice coil motor with fully constrained porous air bearing design and integrated counter balance. 19X Increase in file size handling (up to 4,000,000 points) and 4X faster load line speed (20,000 points / second) compared to previous generation. Our new NanoCAM4^3T CAM software is used to program the NFTS-6000^v2. Dedicated NanoSMART HMI module for ease of use. (brochure available)

Shear Damped Air Isolation System

This optional upgrade to Nanotech’s standard air isolation system provides enhanced vibration isolation and damping in both the horizontal and vertical planes with a natural frequency of ≤ 2Hz.

Precision Air Temperature Control System

Solid State Thermal Electric Cooling (TEC) design is available for all Nanotech lathe systems. Provides 20:1 improvement in temperature variation at the plenum output control point when room variation is within +2˚ C. Extremely advantageous for applications requiring long completion cycles where thermal changes deteriorate part results. (brochure available)

10K RPM PI 4R — Motorized
(Suitable for larger wheels / workpieces)
Air Bearing Grinding & Micro-Milling Attachments

Suitable for larger part grinding as this spindle has the stiffness to support larger size wheels.

60K RPM PI ISO 2.25 — Motorized
(Small to medium size wheels / tools)
Air Bearing Grinding & Micro-Milling Attachments

Most popular Air Bearing Auxiliary Spindle.  Ideal for high speed and extreme accuracy applications such as raster flycutting, micro-milling and micro-grinding of optical molds. A combination of spindle central stiffness, extremely low error motion and powerful brushless DC motor performance. With radial and axial runout of < 25 nm, this spindle is ideal for small ball nose diamond milling tools which require such speed & accuracy for sustainable tool life. In addition, its compact size allows mounting in various configurations on our Oil Hydrostatic Rotary B-Axis.
