The GIDDINGS & LEWIS FTR 3500 is a robust Horizontal Boring Mill, engineered for high precision and demanding applications. Key specifications include a 5.1-inch (130 mm/155 mm available) spindle diameter, driven by a 75.2 HP (56 kW) motor capable of 4,000 RPM. This model features substantial travel capacities, with an X-Horizontal Travel of up to 10,000 mm (157.1 inches or 32.8 ft depending on configuration) and a Y-Vertical Travel of up to 5,000 mm (79.2 inches or 16.4 ft). It incorporates a ram-supported spindle, adding 1 meter of W-axis reach beyond the standard 39.4 inches (1 meter) Z-Spindle Travel, enhancing reach and versatility. Precision is maintained with linear positioning accuracy of 0.015 mm and repeatability of 0.008 mm, supported by a rigid box-welded column construction and steel runway fabrication. The machine typically operates under a high-end CNC control system, such as the Siemens 840D Solution Line or Fanuc, and can be equipped with large-capacity tool magazines (60 to 120 tools) and automated attachment changing capabilities. Optional features include thermal compensation software, chip conveyors, and industrial probes, solidifying its role as a high-performance machining center.
