LB321

Overview
Specifications
  • 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.

Keep It Under Cover

A full-enclosure option is available for all bridge machines. Contain coolant and filter out chips for more effective machining in a cleaner environment.

Heavy Cutting Capabilities

A Meehanite cast iron base and dual bridge columns provide excellent vibration dampening during large-part machining for rigid, precise cuts.

Full of Features

Toyoda’s progressive filtration system for coolant through spindle prevents clogging and reduces thermal expansion, while high-quality THK roller guides provide stability without sacrificing speed. 

Fully Programmable Five-Face Machining

Increase your machining capabilities and flexibility. Five-face machining is an automated system option that reduces the number of setups needed and allows machines to cut in full five-face machining with standard five-degree indexing and optional one-degree indexing on the head.
