K -- MODIFICATION OF AN ELECTRO CHEMICAL MACHINING (ECM) PROTOTYPE MA CHINE POC Errol Chisholm email=chisholm, Contract Specialist, 201-724-5770 Beverly F. Wasniewski, Contracting Officer, 201-724-2164. The U.S. Army ARDEC is seeking information and potential sources to develop improved electro chemical machining techniques for an Electro Chemical Machining (ECM) prototype machine that is installed at Saco Defense Inc. (SDI), Saco, Maine. This machine is designed to rifle 20mm thru 30mm cannon barrels. The proposed effort must be conducted at SDI's facility because it is not technically or economically feasible to move the ECM prototype machine due to its size and complexity. During the first year of the proposed effort, the potential contractor shall develop improved process parameters and tooling configurations for rifling 25mm M242 gun barrels on the ECM prototype machine. Barrel blanks shall be manufactured for the ECM operation. Using the ECM prototype, the contractor shall develop the operating parameters and techniques required to Electro Chemically machine barrels that conform to the applicable specification. A process demonstration is required. Electro Chemically machined barrels shall be manufactured for out year testing. During the second year of the proposed effort, the contractor shall further refine and expand the ECM process to include the rifling of barrel liner materials such as refractory metals and ceramics. The proposed effort will result in generation of a final report, recommendations for equipment, process requirements, purchase descriptions, prototype tooling, and Electro Chemically machined barrels for out year testing. This is only a Market Survey, not a pre-solicitation notice. If a formal solicitation is generated at a later date, a pre-solicitation notice will be published. Respondents should submit their qualification data within 30 days from the date of this publication. Telephone requests are not acceptable. Fax's may be sent to (20l)724-4195. (0062)
