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 ample 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‑section structure, with thick‑walled internal stiffeners and stress‑relief circular‑hole stiffeners, providing robust support for the slide table 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 and NSK series, offering exceptional axial and radial load capacity to ensure reliable performance during prolonged heavy‑duty cutting operations, with outstanding precision, stability, low friction, excellent heat dissipation, and superior spindle support rigidity.
6. X/Z Axis: Employs FANUC AC servo motors paired with large-diameter ball screws (C3-grade precision, 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. Lubrication System: This machine features an automatic pressure‑relief lubrication system that employs centralized oil supply and an advanced pressure‑relief, intermittent lubrication mechanism. It delivers oil to each lubrication point at the appropriate time and in the proper quantity, using timed, metered, and pressure‑regulated intervals, thereby ensuring that every lubrication point receives adequate lubrication and enabling the equipment to operate reliably over extended periods.
9. Fully Enclosed Sheet Metal: In response to today’s stringent environmental protection requirements and concerns for operator safety, sheet metal design places particular emphasis on aesthetic appeal, environmental sustainability, and ergonomic considerations. The fully sealed sheet‑metal enclosure effectively prevents coolant and chips from splashing outside the machine, keeping the surrounding area clean. Additionally, both sides of the machine are equipped with coolant‑flushing systems that direct coolant onto the base, minimizing chip accumulation on the floor.
