Bridgeport GX 320 5F VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a **12.6" x 12.6" table** capable of supporting workpieces up to **330 lbs**, designed for medium-duty precision machining. It is equipped with a **#40 Big Plus vertical spindle** delivering up to **12,000 RPM** and rated at **25 HP (30-minute rating)**, ensuring high-speed and high-power operation for demanding milling, drilling, and boring tasks. The spindle's Big Plus taper offers enhanced rigidity and accuracy by allowing spindle nose contact during tool holding. The machine utilizes a **48-tool automatic tool changer (ATC) with a swing arm design**, enabling efficient tool management and reducing tool change time to approximately **2.5 seconds**, with chip-to-chip tool change times around **4.3 seconds**, supporting continuous, productive operation. It supports **5-axis machining** with travels of **20" on the X-axis, 24" on the Y-axis, 20" on the Z-axis**, and an A-axis rotation of **150 degrees**, offering versatility for complex part geometries and multi-surface machining. The maximum rapid traverse speed on the linear axes is **1,693 IPM (inches per minute)** and a maximum feed rate of **787 IPM**, supporting fast, precise positioning and efficient material removal rates. This machine's combination of a rigid, midsize table, high-power spindle, fast ATC, and 5-axis capability makes it suitable for precision components in aerospace, automotive, mold making, and general engineering industries requiring complex 3D machining with demanding cycle times.
