The Flat Bed CNC Lathe – LC 30 is built to deliver heavy‐duty turning performance for large diameters and long parts. With a swing‐over‐bed capacity of 770 mm (30") and center height of 390 mm (15.3") (for the LC-30 model) , it is designed for industries such as heavy equipment, energy, and fabrication where size and rigidity matter. Its robust flat‐bed box-way construction, combined with Fanuc control readiness and hydraulic turret options, provides the stable foundation needed for both roughing and precision turning in demanding applications.

Engineered for flexibility and productivity, the LC 30 supports a variety of bed lengths (from 1,200 mm up to 3,200 mm and beyond) , generous spindle bore and heavy workpiece capability, and extensions like tailstock quills and chip conveyors. Whether you’re machining oversized rollers, shafts, or large scale housings, this model gives you the durability, control, and precision required for heavy turning tasks in modern manufacturing environments.
