With 50 years of specialist knowledge of this milling machine BRAITHWAITES are the UK 's # 1 choice for rebuilding the Bridgeport.

Using setting gauges, precision squares, bedding plates and dedicated jigs acquired when the Bridlington site closed along with the Bridgeport trained machine toolcraftsmen you are guaranteed quality.

Terry Braithwaite, founder of Braithwaite Rebuild, started a craft apparenticeship with Adcock and Shipley in 1968 . Adcock and Shipley , who later became Bridgeport machines, manufactured the Bridgeport under licence at the purpose built Bridlington site. A total of 50,000 Bridgeports where manufactured . Bridgeport produced over 300,000 machines in America. The Bridgeport is still the preferred manual machine for machinists and toolmakers. Ballscrews on the X and Y are now fitted as standard.
