FBL-510/ 520/ 530/ 540/ MC
Heavy Duty CNC Lathe Machine – FBL 500 Series
The FBL Series Heavy Duty CNC Lathe Machine from FOCUS CNC is engineered for large-diameter turning, heavy cutting, and demanding industrial applications. Equipped with a 4-speed gearbox spindle and a 45kW high-torque spindle motor, this CNC heavy duty lathe delivers the power and stability required for machining oversized and hard-to-cut workpieces.
The slant bed structure with a low center of gravity ensures safer handling of large components while enhancing chip removal efficiency, preventing thermal deformation during continuous heavy-duty operation. With superior rigidity and optimized design, the FBL heavy duty CNC machine guarantees precision, reliability, and long-lasting performance.
