Left and right tool holders of DVT52 series are controlled by DVT system and equipped with digital display scale.
High Efficiency
The table can bear large tonnage load with good stability, high efficiency, safety and reliability.
High Performance
Its excellent structural performance and strong rigidity can meet the requirement of strong cutting.
Implement the latest national precision standard and safety standard, equipped with advanced and reliable electro- mechanical components at home and abroad.
Servo drive and X.Z axis feed servo motor are adopted from Beijing Super Synchronous products.
The X and Z axes of the left and right tool holders are driven by servo motor through precision planetary reducer to increase the torque to drive the ball screw for horizontal and vertical movements.
Product Overview
The DVT5250 DRO Double Column Manual Vertical Lathe is a stalwart of large-scale manual machining, designed to handle oversized workpieces that exceed the capacity of CNC models. Its double-column structure—constructed from reinforced cast iron—provides exceptional rigidity, supporting 40-ton workpiece loads with minimal deflection, even during heavy cutting operations. Equipped with a digital readout (DRO) system featuring a high-resolution LCD display, it allows operators to achieve precise positioning (up to 0.001mm resolution) without the complexity of CNC programming, bridging the gap between traditional manual lathes and automated systems. The machine’s robust design includes large-diameter guide rails, heavy-duty bearings, and a powerful drive system, ensuring reliable performance in demanding industrial environments.
Applications
Shipbuilding: Machining propeller hubs with large diameters, engine foundations requiring flatness within 0.05mm/m, and stern tube housings for marine engines.
Power Generation: Fabricating nuclear reactor components with strict material integrity requirements, steam turbine casings with complex internal passages, and generator end shields.
Heavy Fabrication: Producing large gears with diameters up to 5 meters, pressure vessels with thick walls, and custom structural components for industrial plants.
The DVT5250’s open design allows easy access for manual adjustments, inspection, and workpiece loading/unloading—facilitated by overhead crane compatibility—making it suitable for one-off prototyping and low-volume production of oversized parts.
