The Flat Bed CNC Lathe – LD 50 is a heavy-duty CNC turning machine engineered for large and demanding machining applications. Featuring a generous swing-over-bed capacity of 1,265 mm (50″) and a swing-over-cross-slide of 850 mm (33.5″), it provides the strength and work envelope needed to handle oversized shafts, rollers, housings, and structural components commonly found in energy, marine, mining, and heavy equipment manufacturing.

Built on a robust flat-bed design with a wide cross slide and powerful spindle system, the LD 50 delivers stable, precise cutting performance across long axis travel. Its rugged construction and high load capacity make it suitable for both heavy roughing and precision finishing operations. Standard features include FANUC control and servo systems, hydraulic turret, auto lubrication and coolant systems, and a hydraulic tailstock with rotating quill. Optional accessories such as spindle oil chillers, C-axis indexing, and steady/follow rests further enhance its flexibility for complex machining tasks.

Features

1.High Torque Gearbox
Delivers massive torque with a 1:167 gear ratio and M code 4 step shifting, ensuring full horsepower even at ultra low rpm.
2.Large Bore, High Rigidity Spindle
Three point bearing headstock with 6”–21” large spindle bores and optional twin chucks
3.Ultra Rigid Bed with Triple V Guideways
One piece floor type casting with triple V guideways plus auxiliary slant guide for superior rigidity when machining large diameter parts.
4.High Accuracy Long Travel Z Axis System
Long bed models feature REDEX preloaded helical gears and GUDEL precision rack with linear scale for consistent long travel accuracy.
5.One Button Quick Change System
One button quick change system allows instant switching between turret, milling head, boring bar holder and grinding head for true multi process flexibility.
