The Flat Bed CNC Lathe – LC 45 is designed for heavy-duty machining of very large components, featuring a swing-over-bed capacity of around 1,145 mm (45″) and a swing-over-cross-slide of approximately 735 mm with a center height of 585 mm. Its rigid flat-bed box-way structure, combined with CNC control and heavy-part configuration, ensures exceptional stability, precision and durability for demanding industrial turning operations such as shells, machine bases and large flanges.

Built for maximum flexibility and scale, the LC 45 supports extended bed lengths (such as 3,200 mm and greater) and offers accessories like hydraulic tailstocks, steady/follow rests, and chip conveyors. Whether you’re roughing massive shafts or finishing large rollers, this model delivers the strength, control and performance required for heavy-duty turning tasks in modern manufacturing environments.
