DeVlieg 4B-60 Spiramatic: NC vs Dial Input Technical Article
Technical article from Metalworking magazine (February 1962) examining the trade-offs between numerical control (NC) and dial input systems for DeVlieg 4B-60 Spiramatic Jigmill machines equipped with Diatrol controls. The piece analyzes production efficiency gains—NC systems deliver up to 25% improvement in cycle time—against the capital investment differential (NC-equipped machines at $75,000 versus $50,000 for dial input variants). Documents real-world short-run precision machining for aerospace and missile component manufacturers, with emphasis on tight angular tolerances in gearbox assemblies. Covers high-precision techniques for nodular iron, high-strength steel, titanium, and magnesium castings and forgings, offering practical guidance for machine shops evaluating automation investment for specialized production runs.
