DF Series

Heavy-Duty Hard-Rail CNC Lathe for Shaft & Casting Parts

DF lathes feature rigid hard rail structure and cast iron bed optimized through finite element analysis. They provide strong rigidity for heavy cutting and precision turning of small precision parts and large heavy workpieces. All machines adopt the FANUC 0i-MF PLUS numerical control system to ensure flexible operation and long-term stable working performance.

This rigid hard-rail lathe is designed for all-round metal cutting. It delivers great performance in turning, grooving, threading and contour machining, perfectly fulfilling high-accuracy and high-volume processing needs for mechanical parts in various sectors.

Machine Composition

One-Piece Casting Bed

One-piece 30-degree slant bed made out of Meehanite cast iron, which has superb vibration absorption characteristics, provides rigid foundation for all machine components. Such design endures long-term machining accuracy and consistency. In addition, 30-degree slant bed design provides operators with convenient access to the workpiece and superb chip discharge.

High-Precision Hand Scraping

The full-contact precision hand scraping of all core mating surfaces ensures exceptional anti-vibration performance and consistent cutting precision even under heavy load conditions.This high-precision scraping process greatly reduces long-term frictional wear of all moving parts, maintaining the machine’s original factory accuracy for years of continuous production.

Standard Servo Turret | Efficient Turning for Conventional Shaft & Disc Parts

Equipped with standard servo turret, the machine completes outer diameter, inner hole, thread and groove turning in one clamping. Stable indexing positioning ensures consistent dimensional accuracy for mass production of carbon steel, stainless steel and aluminum shaft, flange and sleeve workpieces. Ideal for general hydraulic parts, standard fasteners and auto conventional components with simple turning procedures.

Power Turret with Y-Axis | One-Setup Turn-Mill Compound Machining

High-performance power turret with Y-axis function integrates turning, milling, drilling and tapping processes. Complex features including flat surfaces, radial holes, offset slots and eccentric profiles are fully finished without secondary clamping. Perfect for precision medical shafts, aerospace aluminum flanges, hydraulic valve blocks and fluid connectors, greatly reducing clamping errors and boosting overall processing efficiency.
