USED BRIDGEPORT 1-1/2 HP

The Bridgeport Series 1 is a vertical knee milling machine featuring a 9 inch x 42 inch T-slot work table. It is equipped with a 1.5 HP motor and an R8 spindle taper. The machine offers a variable speed range from 60 to 4,200 RPM, managed through a high-low range switch and a variable speed dial. Technical specifications include a longitudinal travel of 32 inches, cross travel of 12 inches, and a 5-inch quill travel. The spindle construction utilizes a 2J head with a patented air-cooling system designed to minimize heat buildup in the bearings and belt housing. Precision is supported by chrome-plated ways and gibs, which are hand-scraped to ensure accurate geometry and rigidity. This configuration includes a Sino SDS6-2V two-axis Digital Readout (DRO), a servo power feed for the X-axis, and a Bijur one-shot lubrication system that provides metered oil to all ways and screw assemblies. The machine operates on a 230V, 3-phase power supply and occupies a floor footprint of approximately 6 feet x 5 feet with a height of 7 feet. The net weight of the unit is approximately 1,930 to 2,200 lbs.
