Mill Turn Machine for the Watervliet Arsenal

Specification for Mill Turn Machine Spec. # 01-26-3416 Manufacturing Engineering Work Group Watervliet Arsenal Watervliet, New York 12189 29 JAN 26 Department of the Army TACOM -- 1 of 47 -- 1 1. Scope: The dedicated function of this specification is the acquisition of a machine tool equipped as herein described. All sections are specific in their intent and are not to be misconstrued as requests for options. The machine system described by this specification shall be provided with all required equipment whether stated requirements are standard or optional with the machine tool builder/supplier. This project is classified as a “turn-key” system with the contractor being responsible for all costs and work associated with the installation unless otherwise stated. In this specification, requirements and terminology are oriented toward the purchase of a single machine tool. However, in many cases, two or more identical machine tools will be procured in accordance with this specification. In such cases, the term "the machine" means "each machine". 1.1. Abbreviated Description: The machine tool covered by this specification shall be a New CNC Milling Turning Machine, heavy duty type. Fitted with 2 spindles, slant bed with one piece base. With CNC controlled 5-axis (X, Z, Y, C, and B) Millturn, complete with 2 self- centering c-rest, coolant system, automatic chip removal system, automatic tool changer and other features and characteristics as specified herein. The slant bed shall be of heavy-duty full box construction four rail design. The preferred machine is a NT6600DCG/6000. The contract shall be for one machine with an option for a second machine. 2. Applicable Standards and Publications: All work performed and procedures followed in association with this project shall meet or exceed all applicable and current Watervliet Arsenal (WVA), Occupational Safety and Health Administration (OSHA), local, state, and federal government codes and laws relative to fire, safety, environmental, and electrical issues. These standards include, but are not limited to, ANSI, NFPA, ISO, and ASME. The quality of all work performed and material provided shall meet or exceed the most recent revision of applicable industry standards and engineering practices for this type of equipment and its intended function. In all instances material, quality, and workmanship shall meet or exceed OEM specifications. 3. General Requirements: All requirements are mandatory from the standpoint of intended function. Wherever a specific requirement would force an offeror to depart from his standard practice or configuration, the Arsenal will accept, for evaluation and approval, alternative offers for achieving the intended function. Any such alternative offers must be accompanied by sufficient technical information to allow the evaluator to reach a definite conclusion that the alternative is equal to or better than the criteria specified in this document. The equipment specified in this document shall be a standard product of the manufacturer and shall require either no design changes, or if required, minor design changes to meet the requirements of this specification. Therefore, ownership of the design shall remain with the manufacturer. Equipment incorporating new or unproven technology is subject to rejection at the discretion of the Watervliet Government Representative. NOTE: Not all general requirements listed in section 3 shall be applicable to every machine. If a section is non-applicable, the offer is still in compliance. Please note in the attached Offeror's Statement of Compliance if a section does not apply with the offered machine. -- 2 of 47 -- 2 3.1. Design and Engineering: The equipment specified in this document shall be designed and engineered in accordance with the most current version of each standard, recognized by the Association for Manufacturing Technology. 3.2. Materials and Components: Materials and components incorporated in the construction of the equipment specified herein shall be new, free from defects, and conform to the specifications and standards included within this document. 3.3. Construction: All parts of the equipment specified in this document shall be new, unused, and constructed to be capable of withstanding all forces encountered during operations within the equipment's maximum factor of safety rated capacity. The structure and assembly of the machine and its components shall be sufficiently rigid that workpiece finish and accuracy are not impaired by machine vibrations. 3.3.1. Alignment Retention: Non-integral machine components, heads and ways, which are separately assembled and whose alignments determine the squareness and parallelism of machine geometry shall utilize a positive means for retaining alignments and regaining them in the event of unintentional dislocation. 3.3.2. Slideway Design and Construction: All precision ways which guide and bear the rated design loads shall adhere to the hardness criteria shown in the examples below of acceptable way systems. Slideway systems other than the ones referred to below may be offered provided that their design is consistent with all specified performance characteristics of the machine. All slideway systems having less than a 60-degree incline to the horizontal shall be protected by way covers unless it can be substantiated that covers will interfere with machine functions. Hardness tests other than Rockwell shall be subject to approval by the Watervliet Government Representative. A. Integral cast iron ways shall be hardened from RC 50 to RC 54 to a depth of .100 inches or more. B. Hardened and ground steel ways for mating with Turcite, Rulon, or other such low friction forgiving materials shall be hardened within the range of RC 55 to RC 62. Actual hardness within this range shall not vary more than 5 RC points. C. Hardened and ground steel ways for use with anti-friction roller bearings shall be to a hardness of RC 62 to RC 65 to a de…
