The LB321 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 LB321YM model has extended Y-axis travel with five-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.

CASE STUDIES
What It Takes To Win The Manufacturing Race
The addition of a right angle head for 5 axis machining played a major role in a significant reduction of set up time and machining capabilities. One of the simple return on investments of this machine is its ability to run repeat parts and processes, improving overall cash flow and allowing operations to be run around the clock.
Rigidity, Reliability of Machines Aid In-House Production
“(Toyoda’s) uptime is better than the other brands we have … It might take three cuts on another machine to remove the same amount of metal as one cut on a Toyoda.” - Bob Standridge, owner & founder of Standridge Color Corporation
