SAP PURCHASE REQUISITION: 4200263337 CNC MILL, REQUIRED TO MACHINE AND FABRICATE MODELS TO SUPPORT ON GOING ARC JET TESTING OF SPACE FLIGHT PROJECTS SUCH AS CEV AND MSL. CNC CONTROLLER, SOFTWARE, AND TOOLING COMPATABILITY MUST BE MAINTAINED WITH EXISTING HAAS CNC MACHINES ALREADY IN USE IN THE CERAMICS LAB. FOR THIS REASON, THE CNC MUST BE MANUFACTURED BY HAAS AND MUST SHARE THE SAME SPINDLE TYPE, CONTROLLER, AND SOFTWARE. THIS MACHINE WILL BE USED FOR FABRICATION OF ADVANCED TEST ARTICLES FROM UNIQUE AEROSPACE MATERIALS FOR ARCJET TESTING. THESE MATERIALS ARE EXTREMELY SENSITIVE TO CONTAMINATION AND AS SUCH, THE MACHINING AREA MUST BE FREE FROM OIL AND GREASE CONTAMINANTS DURING ALL PHASES OF OPERATION. THE STANDARD SPINDLE FOR THIS MACHINE DRIPS OIL DURING NORMAL OPERATION, HOWEVER, SELWAY MACHINE TOOL COMPANY HAS VERIFIED THAT THIS MACHINE CAN BE PURCHASED WITH A CUSTOM ORDER OPTION FOR A GREASE PACKED SPINDLE THAT WILL NOT LEAK OR DRIP GREASE OR OIL. THEY FURTHER CONFIRMED THAT THE GREASE PACKED SPINDLE WOULD ENSURE A CONTAMINATION FREE WORK AREA.
