BRIDGEPORT 3020 VERTICAL MACHINING CENTER

Technical Description

The Bridgeport VMC 3020 is a CNC vertical machining center designed for precision and high production with a sturdy footprint and robust specifications. It features a 36" x 18" T-slot table supporting workpieces up to approximately 2,000 lbs. The machine offers 30" travel in the X-axis, 20" in both Y and Z axes, allowing versatile machining volume. Rapid traverse rates reach 826 IPM on the X/Y axes and 710 IPM on the Z-axis, optimizing cycle times for complex parts. The spindle accepts CAT40 tooling with a powerful 12 HP main motor. It runs at variable spindle speeds with a low-speed range of 6,000 RPM constant and 7,500 RPM for 30 minutes, and a high-speed range of 8,000 RPM constant up to 10,000 RPM for 30 minutes, enabling machining of a range of materials from aluminum to titanium. The machine is commonly equipped with a Fanuc 21i-M CNC controller, 2-speed transmission, coolant, and oiler systems, and often includes a high-speed look-ahead and surface milling functions. Its construction and control support high accuracy and repeatability, suitable for aerospace, automotive, and medical prototyping environments. The unit weighs approximately 8,500 lbs and measures about 98" x 110" x 100". It operates on a 230V, 3-phase power supply and features a tool changer carousel with a typical capacity of 22 tools, reducing tool change times to around 4.8 seconds. The VMC 3020 is widely respected for durability, ease of maintenance, and precision in demanding industrial applications.
