System 3R puts continuous effort into developing products for new fields of application. “MacroNano, designed to improve standards of workpiece and electrode management accuracies, is just such a product,” said a company spokesperson. “Not so long ago, nanotechnology (accuracy to less than 0.000040 inch) was regarded as unachievable when machining with conventionalmachine tools,” said the spokesperson. “Now, nanotechnology is becoming a reality in an increasing number of EDM, wire EDM and milling and grinding machines. Nonetheless, a precondition for nano-machining is that the workpieces, electrodes and cutting tools must be mounted and managed with an equal or better level of precision. “Offering extreme system accuracy, System 3R’s MacroNano is a pallet systemdesigned to achieve just this. Using MacroNano, workpieces can be quickly and easily moved from machine to machine, throughout the entire process chainwithout losing any of the system’s ultra precision. “MacroNano’s ‘split-micron’ precision comes from the system’s components (chuck, pallet and drawbar) having been designed and produced using the very same nanotechnologies that they were built to serve. All chuck references are in cemented carbide and there is a pneumatic sensor functionThat ensures correct engagement of all reference surfaces. Pallets are hardened and rust-resistant. They also have all references in a single plane; no shearing forces. Ground-in references arranged crosswise permit 90-degree indexing and a floating drawbar with ball-grip on ground surfaces gives symmetrical traction. Resistance tomachining forces is unsurpassed. “Studies at Fraunhofer IPT in Aachen, Germany, show an indexing a c cur a cy of be t t e r than 0 . 5 ìm (0. 000020 inch) for a part produced using diamond flycutting and Macro- Nano’s built-in indexing function (4 x 90-degrees). This result was achieved even though more than one machine was involved in production.” For more information contact: Dan Pilolla, President System 3R USAInc. 915 Busse Road Elk Grove Village, IL 60007 847-439-4888 dan.pilolla@system3r.com www.system3r.com
