LB533 | JTEKT Machinery North America

Bridge Mills and Gantry Mills

Power and endurance for heavy jobs demanding accuracy and high productivity.

LB533

The LB533 is a double column, fixed rail bridge machine designed for heavy cutting applications. It features a robust geared-head spindle, a hydraulic counterbalance system on the headstock, and a Meehanite cast iron base. These features allow the machine to excel in the heaviest of cuts.

The LB533YM model has extended Y-axis travel with 5-face machining capabilities to allow for the machining of complex workpieces. This machine features automatic tool changes in the vertical and horizontal orientations and offers automatic clamping of the headstock. Headstock options include 30 degree, 90 degree, extension, and manual universal.
