CNC Lathe Machine for Cutting High-Strength and Large Parts

Product Overview

The Slant Bed CNC Turret Lathe is a high-performance machining solution engineered for precision, durability, and versatility in heavy-duty industrial applications. Equipped with the advanced FANUC Oi-TF CNC Control System, this lathe delivers exceptional accuracy and operational efficiency, making it ideal for industries requiring consistent results in large-scale or complex machining tasks.

With a maximum swing diameter of ø 640 mm and a maximum machining diameter × length of ø 420×800 mm, it handles a wide range of workpiece sizes, from medium to large components. The robust spindle, capable of reaching 3000 RPM, paired with a 15 KW spindle motor, ensures powerful cutting performance even in tough materials like hardened steel or high-strength alloys. Whether for batch production or custom part manufacturing, this lathe combines rigidity, speed, and precision to meet the demands of modern manufacturing.

Product Specifications

Machining Capability

The lathe excels in handling diverse workpiece sizes, with a spindle bore diameter of ø 80 mm and a maximum bar machining diameter of ø 70 mm. It supports workpieces up to 300 KGF in weight, making it suitable for heavy components such as industrial shafts, hydraulic cylinders, and large gears. The generous machining envelope ensures flexibility for both short and long parts, eliminating the need for multiple machine setups.

Spindle & Chuck

At the core of its performance is the high-rigidity spindle, featuring an A2-8 spindle nose type for secure workpiece mounting. The standard 10″ Hollow Chuck provides strong gripping force, reducing vibration during high-speed rotation and enhancing machining accuracy. The spindle’s design, paired with its 3000 RPM maximum speed, balances power and precision, making it ideal for both roughing and finishing operations.

Feed Axes

The X-axis offers a maximum travel of 430 mm and a rapid traverse speed of 20 m/min, while the Z-axis provides 850 mm of travel with a rapid traverse speed of 25 m/min. These axes ensure quick positioning and smooth movement, minimizing non-cutting time and boosting overall productivity. The precise ball screw drives further enhance positioning accuracy, critical for tight-tolerance parts.

Turret & Tooling

Equipped with a 12-station turret, the lathe supports versatile tooling configurations, accommodating external tool holders of 25×25 mm and internal tool holders up to ø 40 mm. This flexibility allows operators to perform turning, facing, threading, and drilling operations in a single setup, reducing workflow interruptions and improving part consistency.

Tailstock & Motor

The tailstock features a 500 mm travel and a 100 mm quill travel with an MT-5 taper, providing stable support for long workpieces. The total machine power of 35 KW ensures reliable performance across all operations, from heavy cutting to fine finishing.

Dimensions & Weight

The lathe has a floor space of 3200×2000 mm and stands 2150 mm tall, with a total weight of 5600 KG—a testament to its robust construction. The 240 L coolant tank ensures efficient heat dissipation, maintaining optimal operating temperatures during extended use.

Optional Configurations

Customize the lathe to specific needs with options including GSK/SYNTEC control systems, a 12-inch hollow chuck, a tailstock center, high-pressure water output (30/50 Bar), a bar feeder, a part catcher, and an automatic door.

Design

The lathe’s design prioritizes durability, precision, and user-friendliness. Its heavy-duty frame, constructed to support 5300 KG of weight, minimizes vibration and flexing during high-load operations, ensuring consistent accuracy. The integration of box guideways enhances stability, particularly when machining heavy workpieces, while the slant bed design improves chip evacuation, keeping the work area clean and reducing thermal distortion.

The FANUC Oi-TF CNC Control System features an intuitive interface, simplifying programming and operation for both experienced and novice operators. Quick-access controls for rapid traverse speeds (20 m/min for X-axis, 25 m/min for Z-axis) streamline setup, while the enclosed workspace (with optional automatic door) enhances safety and reduces coolant splatter.

1. Customisation and rapid response

Non-standard part processing: For special operational requirements (e.g., mining machinery, deep-sea equipment), CNC machine tools can quickly adjust machining programmes to complete customised production of small batches or single pieces.

Mould manufacturing and repair: Cavity machining of casting moulds and stamping moulds relies on CNC milling and EDM, shortening the mould development cycle and supporting rapid production of new models.

2. Enhancing Equipment Reliability and Lifespan

Key components processed by CNC machine tools (such as rotary bearing raceways and engine cylinder blocks) exhibit higher fatigue strength and wear resistance, directly extending the service life of construction machinery under harsh operating conditions.

Surface treatment combined with machining: For example, precise base material machining prior to shot peening reinforcement using CNC machine tools enhances components' resistance to stress corrosion.
