Microfabrication and Micromaching - correct DUN# 142425888

Biotechnology, aerospace, automotive and communications industries need small ultra-precise, three dimensional parts for component miniaturization. Present metal cutting technology is rapidly reaching its limits. A new technology is required to accelerate this trend. Atometric will pursue innovations in ultra-precision multi-axis machine tools. The machining capacity will be within a cube of 50 mm. The machines will be orders of magnitude smaller and less expensive than existing processes, and operating in an office rather than "factory" environment. Phase 1 project objectives are to develop a "first commercial prototype" and deliver it to NIST. Anticipated results will be a prototype 4-axis machine tool with 25-50 mm capacity fitting within a 400 mm volume, axis positioning precision of 0.1 to 1.0 micron, spindle speeds up to 125,000 rpm and an appropriate control module. Technical consequences are to move research from the lab into commercial reality. Atometric will develop pre-process measurement and verification, fixturing, contamination protection, tool change, and development of high speed spindles in the 500,000 rpm range. Potential commercial applications are the economical manufacturing of ultra-precision three dimensional miniature parts far beyond present process capabilities. Our objective is to meet present and future commercial needs of the micro machining world. COMMERCIAL APPLICATIONS: Economical multi-axis machining of small cubic metal parts to micron and sub-micron tolerances, without the need for large machines and a factory, using micromachines that match product sizes and tolerances.
