Nanoform® 250 ultra grind
Standard Features button
Optional Features button
Ulltra Precision Machining System

This revolutionary, flood coolant compatible 2 to 5-axes ultra precision freeform machine is designed for diamond turning and deterministic freeform milling and grinding for the most challenging applications. Common applications: glass grinding for aspheric glass lenses, mold inserts for molding lenses for glass pressing.

 The Nanoform® 250 ultra grind comes standard with Precitech’s UPx CNC machine control that provides a user friendly interface with features designed specifically for increased throughput. It is fast and easy to use and boasts an unprecedented 16 picometer feedback resolution an and industry leading operating system with 0.01 nanometer programming resolution. Sealed natural granite base provides exceptional long term stability. The Nanoform® 250 ultra grind incorporates an FEA optimized dual frame for the ultimate in environmental isolation. The linear motors are driven by true linear amplifiers.

Precitech designs and builds their own hydrostatic oil bearing sideways with optimized stiffness and damping characteristics, liquid cooled slides for thermal stability and our own motorized air bearing spindles that allow us to maintain close control over quality and delivery.

Diamond turning (2 or 3-axes) Direct lathing of optics and optical molds including freeform non-axi-symmetrical designs

Tool Normal diamond turning (3 or 4-axes) Utilizing a contouring B-axis for freeform shapes in challenging materials, such as silicon.

Precision grinding and milling (2 or 3-axes) Utilizing a 15,000 rpm spindle in the 45° or 90° orientation for cross-axis grinding for the direct machining of precision glass optics.

Freeform grinding and milling (3 or 4-axes) Utilizing a 50,000 rpm spindle and a rotary B-axis for parallel grinding or 45° grinding for optical mold inserts, such as tungsten carbide for glass pressing applications.
