Machine Tool Characteristics

1. This machine tool is manufactured using high-grade cast iron and a box-type structural design. After appropriate annealing to relieve internal stresses, the material exhibits exceptional toughness. Coupled with the box-type structure and a highly rigid body, the machine delivers sufficient rigidity and strength, enabling it to withstand heavy cutting operations while maintaining outstanding repeatability and precision.
2. The base and the spindle housing are integrated into a monolithic box-type structure, featuring thick ribbed walls and multi-layered stiffening ribs, which effectively suppress thermal deformation and withstand both static and dynamic torsional and deformation stresses, thereby ensuring high bed rigidity and excellent stability.
3. The column adopts a honeycomb‑type symmetrical box structure, with thick‑walled internal ribs and stress‑relief circular‑hole ribs, providing robust support for the slide during heavy cutting operations and ensuring high rigidity and precision of the machine bed.
4. High-precision, high-rigidity spindle head: This machine is equipped with a FANUC high-power spindle servo motor (rated power 18.5/22 kW).
5. The spindle bearings are selected from the SKF/NSK series, offering exceptional resistance to heavy axial and radial loads, ensuring reliable performance during prolonged heavy‑duty cutting operations. They deliver outstanding precision, stability, low friction, excellent heat dissipation, and superior spindle support rigidity, making them ideal for machining large workpieces and asymmetrical components.
6. X/Z Axis: Employs FANUC AC servo motors paired with large-diameter ball screws (C3-grade accuracy, preloaded to eliminate thermal expansion and enhance rigidity) for direct drive, eliminating the cumulative errors associated with belt-driven systems. This ensures high repeatability and positioning accuracy, while the support bearings are high-precision angular contact ball bearings.
7. The X and Z axes are equipped with ultra-heavy-duty linear guideways featuring high rigidity and a low coefficient of friction, enabling high-speed feed rates while minimizing guideway wear and preserving machine tool accuracy over time. These linear guideways offer a low friction coefficient and excellent dynamic response, delivering superior machining precision and supporting high‑load cutting operations.
8. Two‑speed transmission characteristics:

• 1). No noise and no heat transfer to the spindle
• 2). Vibration-free transmission to the spindle ensures cutting quality.
• 3). The gearbox and the spindle employ a separate lubrication system.
• 4). High transmission efficiency (exceeding 95%)
• 5). Gear shifting is controlled by a gear selector fork, ensuring stable gear changes.

9. ATC Tool Magazine: Equipped with an automatic tool‑change mechanism, the magazine holds 12 tools and features a 7/24 taper BT‑50 shank. Each tool can weigh up to 50 kg, and the magazine has a maximum load capacity of 600 kg. An integrated coolant system ensures effective cooling, extending tool life and reducing machining costs.
10. Electrical Cabinet: The electrical cabinet’s heat exchanger provides efficient cooling, ensuring system stability. The external wiring section is equipped with a protective corrugated conduit that is resistant to heat, oil, and water.
11. Lubrication System: This machine features an automatic pressure‑relief lubrication system that employs centralized oil delivery and an advanced pressure‑relief, intermittent lubrication mechanism. It provides timely and precise oil supply to each lubrication point—on a timed, metered, and pressurized basis—ensuring that every lubrication location receives the proper amount of lubricant, thereby guaranteeing reliable, long‑term operation without maintenance concerns.
