This is a Statement of Specifications document for procurement of a Haas ST20 Small Horizontal CNC Lathe for Arnold Air Force Complex, AEDC, located at Arnold Air Force Base, Tennessee.
The requirement specifies delivery of a new, fully functional horizontal CNC lathe with no refurbished or remanufactured parts authorized. Machine construction must feature Meehanite cast iron base, bed, and headstock with slant bed design, protective guideway covers, internal chip conveyor, and coolant tank. The main spindle requires 20 Hp rating, variable speed to 4000 RPM with high-speed bearings, 3.5" spindle capacity, 2.5" bar capability minimum, standard 10" 3-jaw chuck with hydraulic operation, and A2-6 spindle nose mount. The turret must accommodate 12 station 24-position indexing. Controls specifications mandate manufacturer's latest version with 10" minimum color LCD, 1GB program memory minimum, DNC capability, FANUC protocol compatibility, conversational programming, helical interpolation, Custom Macro B, AC digital servo and spindle drivers, high-speed machining capability, 256MB data server minimum, ethernet connectivity, manual pulse generator, override capabilities, rigid tapping, and power surge protection. Travel requirements include minimum 8" X-axis and 22" Z-axis with ±.0001" repeatability and ±.0001"/12" positioning accuracy. General specifications require 20" maximum swing, 11" minimum turning diameter, 20" minimum turning length, auto lubrication, internal coolant tank, removable splash guards, automatic tool setter with manual and automatic modes, chip conveyor, fully programmable tailstock, and A2-6 QG-80 collet chuck. The contractor must provide lifting and leveling hardware, compliance with NFPA 79 standards compatible with AEDC's 480V 3-phase 60Hz power system (or include step-down transformer), operation and maintenance manuals, standard tooling package, hydraulic collet chuck with collets, and integral coolant tank with pump. The machine includes 24-month warranty covering defects in material, parts, and workmanship for the complete machine and extended 24-month warranty for control, servomotors, and main spindle motor. Service requirements mandate on-site response within 36 hours and repair parts delivery within 48 hours. Delivery is FOB Arnold Air Force Base with contractor-provided preservation and packaging; installation supervision by factory-trained servicemen is included in machine cost, occurring at AEDC Model Shop, West Shop, Building 451, with installation kit provided at no additional cost.
