Revolutionizing Horizontal Machining with U-Axis Technology: A Game-Changer in Precision and Efficiency
For decades, the development of horizontal machining centers has been a crucial aspect of industrial manufacturing, particularly in the production of components for hydraulic tires, engineering machines, petrochemical equipment, cars, bearings, and electrical equipment. The challenges posed by the need to match the requirements of modern treatment, however, have led to the invention of U-axis technology, a game-changer in the field of horizontal machining.
U-axis technology is designed to address the inherent limitations of traditional machining methods, such as the difficulties in achieving high coaxial bore systems with different internal diameters and rigorous coaxiality requirements. This innovative technology combines a CNC control unit, a machine-tool servomotor system, and a connection shaft to link the U and Z axes, enabling the finishing of conical holes, surface R, and threads.
The path to achieving this level of precision and efficiency, however, is not without its challenges. One major hurdle is the requirement for special functionality and mechanical structure of the machine tool, which can be a significant obstacle in the development and production process. Another limitation is the need for advanced programming and processing, which can be a daunting task for even the most experienced users.
Enter the Nigata BFN series, a revolutionary horizontal machining center that has transformed the industry with its unique and innovative approach to U-axis technology. The BFN series boasts an impressive range of features, including:
- A direct installation of the U-axis unit at the end of the high-rigidity pin, ensuring improved rigidity and stability.
- A U-axis stroke of 50 mm and a maximum frame diameter of 300 mm, making it an ideal choice for heavy-duty and high-precision applications.
- A novel short cone and double-contact tool holder, designed to provide exceptional precision and strength.
- A single cooling system that rotates synchronously with the U-axis, providing optimal blade cooling and extended tool life.
- Dedicated programming software (SNAP3), which simplifies and optimizes programming and debugging, reducing the time and effort required to produce complex parts.
One of the most significant advantages of the BFN series is its ability to streamline the manufacturing process, reducing the number of tools required and the amount of assistance time needed. This is exemplified in the example of a composite machining center, which can complete the entire process of "rough treatment → automatic opening measurement → automatic U-axis compensation → finishing treatment" with a single machine.
The user experience is also simplified, thanks to the intuitive programming software (SNAP3), which allows for the creation of macro programs based on user-defined functions. This remarkable tool enables users to input the coordinate values of each inflection point along the treatment profile, reducing the complexity of programming and processing.
Despite these breakthroughs, there are still some challenges to be addressed, including the influence of centrifugal force, which can be mitigated by the G101-UX position compensation function designed by Nigata. By exploiting the benefits of U-axis technology, manufacturers can now achieve unprecedented levels of precision, efficiency, and flexibility, revolutionizing the world of horizontal machining.
Key Takeaways:
- U-axis technology is a game-changer in horizontal machining, enabling the production of complex parts with high precision and efficiency.
