The Fives Giddings & Lewis FTR 3500 is a heavy-duty horizontal machining center designed for large, precision machining tasks with superior rigidity and thermal stability. It features a horizontal #50 taper spindle rated at 60 HP for 30-minute cycles, with an optional upgrade to 1000 HP, and a top speed of 4,000 RPM. The machine is equipped with a 60-tool automatic tool changer (ATC), expandable optionally to 120 tools, supporting heavy tooling up to 50 kg. The FTR 3500 utilizes a collinear ram headstock in addition to the live spindle, providing extended reach and enhanced cutting rigidity. It offers four axes of motion with travels of 157.0 inches (X, optionally to 630.0"), 79.2 inches (Y, optionally 157.2"), and 39.4 inches (Z), all with rapid traverse rates up to 787 inches per minute. The machine’s design includes a modular setup, allowing customization of table/work support and optional rotary or indexed tables to optimize workpiece handling. Constructed with a rigid, box-welded column and cast iron base, the FTR 3500 delivers exceptional stability and durability, minimizing vibrations for heavy cuts. Preloaded roller guides and large-diameter ballscrews ensure precise positioning with repeatability within 0.0003 inches. This machine is ideal for machining large parts found in heavy industry sectors such as aerospace, power generation, mining, and construction equipment manufacturing, supporting maximum workpiece weights up to 99,999 lbs and offering flexible integration with advanced CNC controls for high productivity and accuracy.
