In modern manufacturing, VMC 5-axis machines are becoming key equipment to enhance processing precision and production efficiency. Its advanced design concepts and technical features enable it to excel in tackling complex machining tasks. This article will detail the main structural features of the VMC 5-axis machine and its advantages in practical applications.
VMC 5-axis machine is based on achieving superior five-axis machining performance through standardized and reliable structures. This design philosophy not only optimizes the economic efficiency of the machine tool but also significantly improves machining quality and efficiency. The machine tool is equipped with a high-performance CNC system, which uses a high-performance industrial MCU as the control core, widely applied in CNC machining tools and industrial automation control fields.
The CNC system's external design adopts high-performance plastic housing or a full aluminum modular design, with the main modules compatible with both horizontal and vertical layouts. The accompanying full-digital AC servo drive unit has strong flexible parameter configuration capabilities, excelling in high-precision servo control and high-speed PLC control. The system not only supports standard CNC command systems and data communication interfaces but also features five-axis RTCP and five-axis tilted surface control machining capabilities, allowing for high-precision machining of complex spatial curves.
The overall structure of the VMC 5-axis machine adopts resin sand casting technology. All cast iron components are optimized through three-dimensional design and finite element analysis, ensuring the rigidity and precision retention of the machine tool's motion. The bed features well-designed composite rib plates, providing excellent anti-bending and anti-torsion performance, thereby ensuring the precision stability of the machine tool during long-term operation.
The column part adopts a cross-shaped rib plate, a large-section beam, and a high-rigidity integrated casting structure. Precision hand-scraped contact surfaces further enhance the stability and precision retention of the structure. This design allows the VMC 5-axis machine to meet the high-precision machining requirements in automotive parts, aerospace, medical, and other fields.
High Rigidity Base and Stable Structure
The VMC 5-axis machine adopts a high-rigidity base design to support the rotation of the cradle B and C axes. The X/Z axes use a cross-slide design, ensuring optimal stability required for machining precision and surface quality. The use of a gantry-type high-rigidity structure, cast using resin sand technology and systematically aged, effectively enhances the stability and machining precision of the machine tool.
High Precision Feed System
The X, Y, Z three axes are all equipped with high-rigidity, ultra-precision, medium preloaded linear guides. The feed system adopts large pitch high-precision high-strength C3 grinding grade ball screws. This design ensures precise movement and excellent transmission performance of the machine tool in all directions.
High-Performance Spindle and Chip Removal System
The spindle uses a high-speed, high-precision, high-rigidity electric spindle unit, with a maximum speed of 30000rpm and a rated torque of 6Nm, suitable for high-speed, high-precision machining needs. Additionally, the equipped coolant chip removal system can quickly flush and discharge iron chips into the machine's chip removal cart, convenient and efficient, maintaining equipment cleanliness and good chip removal performance.
High Dynamic Response Rotary Actuator
Equipped with high dynamic response rotary actuator cradle turntable, this actuator features high precision, small size, large torque, and low vibration. Its harmonic drive and zero backlash design ensure high-rigidity continuous rotation and arbitrary angle positioning, with a B axis maximum torque of 169Nm and a C axis maximum torque of 69Nm, truly achieving the advantages of high performance and long life.
