2015 BRIDGEPORT GX300 VERTICAL MACHINING CENTER

Technical Description

The 2015 Bridgeport GX300 is a 3-axis vertical machining center produced by Hardinge Inc. under the Bridgeport brand, designed as a compact, precision-oriented VMC for small component production. The machine features a 23.6-inch by 15.75-inch worktable with a table load capacity of 550 lbs and a 20-tool carousel automatic tool changer with a No. 40 spindle taper. The spindle motor delivers 20 HP (30-minute rating) at a standard maximum speed of 7,083 RPM, with a 10,000 RPM high-speed option available. X-axis travel is 11.8 inches, Y-axis travel is 15.75 inches, and Z-axis travel is 16.93 inches. The machine is equipped with a Fanuc 0i-MC CNC control providing high-speed contouring, rigid tapping, and G-code programming capability. Rapid traverse rates reach 1,181 IPM on all linear axes. Despite its compact X-axis travel, the GX300 is built on a full-size C-frame base and column with linear roller guideways on all axes, providing excellent rigidity for precision micro-milling and fine contouring work. Standard equipment includes flood coolant, automatic lubrication, and tool length measurement. Overall machine dimensions are approximately 57 inches long by 101 inches wide by 93 inches tall. The GX300 is specifically suited for high-precision small-part work in the aerospace, medical device, and electronics industries where tight tolerances and fine surface finishes are required on small workpieces. The compact X travel distinguishes this machine from other GX series models and positions it for niche precision applications.
