About this file
This document is a Salient Characteristics specification for Project #395-320 detailing requirements for a Portable Lathe and Boring Machine.
The specification mandates procurement of a Protem USA LLC Serco Portable Lathe, Model #TU400-1000, with pneumatic drive capability and multiple surface finish options including stock, spiral serrated, cold water, concentric serrated, and smooth finishes. Technical requirements include machining diameter capacity of 0 to 15.7 inches, clamping diameter of 8.6" to 16.9", radial stroke of 1.6", axial stroke of 3.94", dual-speed radial auto-feed of 0.0020 to 0.0059 ipr, variable axial auto-feed of 0 to 0.67 in/min, free spindle rotation up to 77 rpm, working air pressure of 73-102 psi maximum, and air consumption of 53 cfm. The machine must deliver 0.0004" precision for concentricity and parallelism with roughness capability from Ra 32 to 500 µin. The specification includes numerous ancillary components and accessories: three fixing arms, tool and insert holders with carbide inserts, clamping systems, RTJ groove machining device with 30° capacity, conical machining kit, multiple sets of cutting inserts, transport packaging, and 3 days of on-site training. All equipment must be tagged with Item Unique Identification (IUID) per MIL-STD-130.
