66 -- PRECISION AIR-BEARING SERVO-CONTROLLED ROTARY TABLE SOL 52SBNB6C9208 DUE 082996 POC Marsha Rodgers (301) 975-6398 The National Institute of Standards and Technology (NIST) has a requirement for a Precision Air-Bearing Servo-Controlled Rotary Table. The table shall have a drive interface to a Leitz PMM 866 coordinate measuring machine (CCM), capable of horizontal or vertical operation, with a faceplate diameter of approximately 400 mm, and a height from base to top of faceplate no greater than 196.8 mm. The thrust load capacity at least 1136 kg shall be maintained with a minimum stiffness of 125 kg/micrometer. For horizontal operation, the radial motion at 25.4 mm above the faceplate shall be less than 0.025 micrometers and the radial motion at 305 mm above the faceplate shall be less than 0.05 micrometers. For vertical operation, the radial at 25.4 mm above the faceplate shall be less than 0.05 micrometers and the radial motion at 305 mm above the faceplate shall be less than 0.075 micrometers. All certifications of specifications shall be traceable to NIST.--F.O.B. Destination, Gaithersburg, Maryland--Required Delivery Time 18 Weeks-- All responsible sources may submit a proposal which shall be considered by the Agency--Please request copies of the solicitation by fax number (301) 963-7732 (0193)
