Critical Technology Assessment of Five Axis Simultaneous Control Machine Tools

摘要

The Bureau of Industry and Security (BIS) conducts critical technology assessments to examine the impact of export controls on key existing or emerging technologies subject to the Export Administration Regulations (EAR). These technologies are dual-use, meaning they have both civilian and military applications. For a given technology, BIS evaluates the scope and impact of current U.S. export controls, foreign export control practices, the sector's economic status, and the foreign availability of product substitutes. This assessment focuses on machine tools for milling and for grinding having five or more axes that can be coordinated simultaneously for 'contouring control' (i.e., mills, grinders, mill/turns and machining centers). It also examines the health and competitiveness of U.S. manufacturers and distributors, and identifies issues relevant to domestic and foreign procurements by the Department of Defense (DOD) and its contractors necessary to produce and support critical defense systems. Machine tools subject to this assessment are controlled for national security (NS), nonproliferation (NP), and anti- terrorism (AT) reasons under ECCNs 2B001.b.2 and 2B001.c.2 of Supplement No.1 to Part 774 of the EAR.1 This technology assessment does not analyze machine tools that only perform turning operations (i.e., lathes) that are subject to control under ECCN 2B001.a.
