About this file
This is a Specification document for the procurement of a Small Horizontal CNC Lathe for the Arnold Air Force Complex, AEDC. The requirement specifies a new Haas ST20 machine with all materials, labor, and equipment necessary for full functionality; refurbished or remanufactured parts are not authorized.
The machine specifications include Meehanite Cast Iron construction with a slant bed design, a 20 HP main spindle with variable speed to 4000 RPM, 3.5" spindle capacity with 10" hydraulic chuck, and a 12-station 24-position indexing turret. Control requirements mandate the manufacturer's latest version with 10" minimum color LCD, minimum 1GB program memory, DNC capability, FANUC protocol compatibility, conversational programming, helical interpolation, Custom Macro B, and AC Digital Servo & Spindle Drivers. Travel specifications require X-axis of at least 8" and Z-axis of at least 22" with ±.0001" repeatability and positioning accuracy. Additional requirements include maximum swing of at least 20", turning diameter of 11" minimum, turning length of 20" minimum, auto lubrication, internal coolant tank, chip conveyor, and fully programmable tailstock. The contractor must provide lifting and leveling hardware, machine built to NFPA 79 standards for 480V, 3PH, 60 HZ operation, all manuals, bar feed unit, standard tooling package with tooling voucher, hydraulic collet chuck with collet package, integral coolant tank and pump, and Esprit CAM software post processor. Installation will occur at Arnold Air Force Base, TN in Building 451, supervised by factory-trained servicemen and included in machine cost. The machine includes a 24-month warranty against defects in material, parts, and workmanship, with contractor capability to respond to repair service calls on-site within 36 hours and deliver repair parts within 48 hours. Two-day initial training on machine features and operation is included at machine startup.
