- Description
- NASA/MSFC is hereby soliciting information about potential sources for a heavy duty, CNC, 5-axis, bed-type milling machine. This machine will be used in the fabrication and modification of vibration and acoustic test fixtures. Any proposed machine shall be capable of both horizontal boring and vertical milling operations with minimal operator interaction. Operator installation of a right-angle attachment is not acceptable. The machine must be capable of switching configurations from vertical to horizontal at the command of the operator. Any proposed machine must meet the following specifications as a minimum: 1. The machine shall have an articulating head. The head will allow for positioning in two planes. One plane of adjustment will be perpendicular to the milling table top surface and parallel to the table's long axis (plane A) while the other plane is perpendicular to the milling table top surface and perpendicular to the long axis of the table (plane B); thus, allowing for adjustment of the head from vertical milling configuration to a horizontal boring position as well as being capable of left and right tilt. The head position shall be controlled by the CNC controller and will have positive stops no more than 2.5 degrees apart in each direction. The head shall have 360 degrees of rotation in plane A and at least 90 degrees of rotation in plane B. The spindle shall accept V-flanged, CAT-50 taper tooling. 2. The machine shall have travels of at least 72 inches in the longitudinal, 59 inches in the vertical, and 47 in the cross direction. All three axes shall have scaled feedback. Cross travel shall be accomplished via a horizontally stroking ram or spindle. A moving column is not acceptable. The majority of our machining requirements involve machining and drilling operations on flat plates; thus, the machine must allow for machining and drilling of a minimum 44" square plate mounted flat down (on standoffs) to the milling table. It is also not acceptable to have a way or bed protruding from the front of the machine. The operator must have unimpeded access to the work piece and head all along the front of the machine. 3. Table shall be at least 72 inches long by 36 inches wide with 5 rows of ?" T-slots. The table shall support at least 15,000 pounds and function normally under load. 4. Feed rate range shall be at least 0-150 inches per minute. 5. Main spindle speed shall be continuously variable and range from 50 to 2500 RPM. 6. Main spindle motor shall be a minimum 25 horsepower and operate on 480 VAC, 60 Hz, 3 phase power. 7. The machine guarding shall be positioned in such a way as to protect an operator in front of the machine, but allow for long work pieces to be placed in the longitudinal axis of the table. The machine guarding shall be easily manipulated by the operator to allow access to the work piece and head. 8. A probe-type part centering and alignment system shall be included. 9. Ways shall have a minimum hardness of 50 Rockwell C and all guides shall be Turcite coated. 10. The machine shill utilize ball screws on the table, ram, and column. 11. Automatic lubrication shall be included. 12. A complete coolant system shall be included. 13. The machine shall be CNC controlled, but shall also have hand-wheel controls for all three main axes. The CNC controller shall feature an 11 inch color LCD screen and shall have conversational software. No specialized programming language will be required to operate the machine. The control unit shall have programs for drilling in line, circle, grid, and arc formations; boring, reaming, and rigid tapping. It will compensate for tool radius and length. The control unit shall have interpolation features for linear, circular, and operation on inclined planes. The controller shall be mounted on a pendant and be easily accessible from the front of the machine. 14. Total weight of the machine alone will not exceed 40,000 pounds. 15. Positioning accuracy and repeatability shall both be less than 0.001 inch. Resolution shall be less than 0.0001 inch. 16. Machine shall be capable of operation in an environment of between 60 degrees and 95 degrees F. 17. Terms shall be FOB destination. 18. Delivery shall be 60-90 days ARO. 19. Machine installation, start-up, and training shall be included in the offer and shall be a minimum of 5 days onsite at MSFC. 20. Machine shall include a minimum 1 year parts and labor warranty. 21. Machine shall be new. Used equipment will not be accepted. No solicitation exists; therefore, do not request a copy of the solicitation. If a solicitation is released it will be synopsized in FedBizOpps and on the NASA Acquisition Internet Service. It is the potential offeror?s responsibility to monitor these sites for the release of any solicitation or synopsis. Vendors having the capabilities necessary to meet or exceed the stated requirements are invited to submit appropriate documentation, literature, brochures, budgetary quotes, and references. Technical questions should be directed to: Rodney Phillips/ET23/256-544-4145. Procurement related questions should be directed to: Marianne campbell/PS22-K/256-544-6496. Please advise if the requirement is considered to be a commercial or commercial-type product. A commercial item is defined in FAR 2.101. This synopsis is for information and planning purposes and is not to be construed as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resultant solicitation for the requirement. The Government reserves the right to consider a small business or 8(a) set-aside based on responses hereto. All responses shall be submitted to Marianne Campbell no later than June 3, 2005. Please reference NNM05ZET002L in any response. Any referenced notes may be viewed at the following URLs linked below.
