High performance, heavy duty, large capacity machine designed specifically for linear flycutting and grooving applications.

• Microstructures are defined as small-scale surface topologies, generally classified as grooves, lenticulations, and echells, that modify the reflective, transmissive, or diffractive properties of light incident on the surface. Free form surfaces are not symmetrical about any rotational axis, and like micrstructures, require multi-axis machining motions.

• The MGG™ 650 is constructed on a natural granite base and is supported through the use of a self-leveling, pneumatic, isolation system.

• The machine utilizes three linear axes (X, Y, Z), which have travels of 26" (660mm), 24" (600mm), and 3.75" (95mm) respectively. The X and Y axes utilize a hydrostatic oil bearing design driven through the use of the linear drive motors. The Z0axis is a cross needle roller bearing slide design with 3.75" (95mm) of travel, driven through the use of a ball screw and DC brush type motor drive.

• A rotary axis is mounted to the top of the X-axis and provides 360° of rotation. The high speed air bearing spindle is mounted to the vertical Z-axis such that its axis of rotation is parallel to the Y-axis.

• The machine is controlled through the use of Precitech's Ultrapath™ Digital Signal Processor (DSP) based machine control system.
