Simple to use and engineered for high productivity. Our latest generation of the most user friendly and compact ultra-precision CNC diamond turning lathe. Used for the rapid production of spherical & aspheric optical lenses, mirrors, mold inserts, freeform optics, and even mechanical components. If your application fits within a 350mm diameter window (with optional riser package), this machine may be the ideal solution for your ultra precision needs. Achieves both sub-nanometer level surface finishes and sub-micron form accuracies directly off the machine in a wide variety of materials.
Only Nanotech offers a proven and established midsize ultra precision system. The 450UPLv2 is comfortably suitable for both single point diamond turning and deterministic micro-grinding of optical elements. Applications examples include the manufacture of components used in a wide variety of markets such as electro-optics, aerospace, defense, consumer electronics, bearing, and computer industries. As an ideal midsize option for our customers, the standard configuration of this popular machine model yields a 450mm diameter swing capacity, but increased swing capabilities are readily available upon request.
Expansion of the basic 2-axis system is simple. One can have up to 4 axes of continuous path motion via the addition of C & B or C & Y. The C-axis motion control of the work spindle enables toric, biconic, and other freeform surfaces to be machined "on-axis" via our Slow Slide Servo (S3) process. Our Air Bearing Rotary B or removable Oil Hydrostatic Vertical Linear Y-axis can be configured independently on the Z-axis carriage for future added flexibility.
This ideal center mounted thrust plate design, engineered for both heavy loads and high throughput applications, includes the exclusive added durability benefits of Porous Graphite. Guaranteed motion accuracies of less than 12.5 nanometers throughout its 10,000 rpm speed range with total liquid cooling for long term thermal stability.

The upper enclosure is engineered to overlap the inner protective stainless steel apron of the system keeping all swarf / coolant within the desired machining area. Large dual sliding doors allow easy access to the entire work area. Both sliding doors overlap when closed and then simply slide to a "full open" position for easy cleaning / maintenance of the machine's entire interior.
The 250UPLv2 has a natural granite base structure with passive air isolation system. High stiffness and low profile "box-way" style oil hydrostatic slide ways with linear motor drives are engineered into a low center of gravity framework for maximum mechanical stability.
The system was developed with the latest "precision engineered" designs and components, including high stiffness oil hydrostatic bearing slide ways, and state-of-the-art linear motor drives with sinusoidal drive amplifiers.
· Impact Resistant Porous Graphite Air Bearing Work Spindle with less than 12.5nm motion error throughout entire speed range and 0.01 arc second C-axis resolution.
· Industry leading 8 picometer linear feedback resolution.
· Delta Tau Power PMAC Real-time 64-bit Motion Controller with 40,000 block lookahead for advanced trajectory calculations.
· Dedicated Ethernet / LAN connection allows real-time monitoring and control of the machine by the factory (or the customer) to remotely evaluate all control functions for instantaneous diagnosis and troubleshooting of any control or programming problems.
· NanoSMART ™ - Industry’s First Touch / Swipe Gesture Based Interactive HMI with numerous new value added features including ability to process up to 5GB program file sizes.
Featuring a high speed 64 bit Delta Tau PowerPMAC, this motion controller is the industry's first touch / swipe gesture "smart" screen display. Three customizable 22" wide screens are accessible by swiping left or right from the main screen. Now you have the option to easily create and save your own custom user friendly interface screens to satisfy a particular individual's preference or a specific application. 5GB program file sizes, 4X faster processing speeds, remote diagnostics and an industry leading 8 picometer feedback resolution combine to make the new Nanotech 450UPLv2 the most operator friendly high performance mid-size diamond turning system available.
