By Chris Felix W hen the subject of micromachining comes up, people often think immediately of tiny parts. But it's really more about the technology that allows the production of these parts, and that technology can be applied to features on parts of any size. Micromachining requires a certain level of precision that isn't easily attainable; the right tooling and workholding, finishing processes and inspection and quality control must all work flawlessly together to produce these types of parts to the standards set forth by today's electronics, automotive, medical, aerospace and other industries requiring small features with such tight tolerances. One shop in Batavia, Ohio, just east of Cincinnati, knows what it takes to serve up this level of precision. We've written about American Micro Products Inc. (AMPI) before. Founded in 1957, the company has been a well- respected leader in the field of precision machined compo- nents. Its global reach and its capabilities in micro and high precision manufacturing have allowed AMPI to serve a variety of high-technology markets, including automo- tive, diesel fuel system components, aerospace, medical and industrial, among others. Today, the corporate headquarters, with core compe- tencies of electrical, mechanical and test and measure- ment services, includes 140,000 square feet of floor space and employs about 200 people. e company also has a 40,000-square-foot manufacturing facility in China (Micro Global) that employs 100 more. Mixed with its long list of internal capabilities, including automation, plating, maintenance and finishing, it has formed a network of outside services that include casting, coating, forging, heat treating, laser welding, metal injection molding and extrusion. With strategic alliances with its customers, the company can better understand their needs and how its Micromachining is About Precision combined resources can offer the advantages necessary to meet the customers' goals. AMPI has established a reputation for quality custom products including custom connectors, feed-throughs, headers, hermetic packages, match seals and ceramic seals. Its precision machining capabilities include turning from 0.1 mm to 150 mm, turning lengths as long as 600 mm, milling to 800 × 410 × 510 mm and tolerances to ±0.001 mm. :: American Micro Products features a spectrum of inspec- tion and quality control instruments for verification of micro-precision parts. Holding tolerances on very small part features is not for the faint of heart. The skill is not only in the machining, but cleaning and inspection as well.
