Adding a Second B-Axis Enhances Efficiency in Swiss-Type Machining.

The introduction of a second B-axis on Swiss-type lathes significantly enhances their efficiency and versatility, enabling more complex machining operations with improved precision. This advancement is particularly exemplified by Nomura DS’s 20J3XBTC model, which features a highly stable, fully programmable B-axis on both the main and subspindle.

Key Benefits of the Second B-Axis

Increased Tooling Capacity and Versatility: The second B-axis on Swiss-type lathes like the 20J3XBTC allows for additional tooling capacity. The main spindle can hold five live tools, while the subspindle can accommodate four. This configuration enables the machine to handle both roughing and finishing tools efficiently. The ability to go up to 6,000 rpm on live tools, combined with high-pressure coolant systems, further enhances the machine’s capability to manage complex parts and intricate geometries.

Enhanced Machining Flexibility: With a second B-axis, Swiss-type lathes can perform a wider range of operations without the need for additional setups. This flexibility is crucial for reducing production times and increasing throughput. The programmable B-axes allow for precise angular positioning of the tools, which is essential for machining features that require complex angles and contours.

Improved Efficiency and Productivity: The additional B-axis contributes to significant improvements in machining efficiency. By enabling simultaneous operations on both spindles, the machine can complete parts faster and with greater accuracy. This dual-spindle operation reduces cycle times and increases overall productivity, making it an ideal solution for high-volume production environments.

High Stability and Precision: The robust design of the B-axis ensures high stability during machining operations. This stability is crucial for maintaining precision, especially when machining complex parts that require tight tolerances. The fully programmable nature of the B-axis allows for repeatable and accurate positioning, which enhances the quality of the finished parts.

Applications and Industry Impact

Complex Part Machining: The second B-axis is particularly beneficial for industries that require complex part machining, such as aerospace, medical, and automotive sectors. These industries often deal with intricate components that necessitate multiple operations and precise geometries. The enhanced capabilities of Swiss-type lathes with dual B-axes make them well-suited for these demanding applications.

Reduction in Setup Times: The ability to perform multiple operations in a single setup reduces the need for frequent tool changes and reconfigurations. This reduction in setup times leads to higher machine utilization rates and lower production costs. Manufacturers can achieve greater efficiency and flexibility in their production processes, which is essential for maintaining a competitive edge.

Quality and Consistency: The precise control offered by the second B-axis ensures consistent quality across production runs. This consistency is vital for industries where part integrity and reliability are paramount. The enhanced repeatability of Swiss-type lathes with dual B-axes ensures that each part meets the required specifications, reducing the likelihood of defects and rework.

Conclusion

The integration of a second B-axis in Swiss-type lathes represents a significant advancement in machining technology. It offers increased tooling capacity, enhanced flexibility, improved efficiency, and high stability, making it a valuable addition to modern manufacturing environments. Industries that require complex and precise machining operations can greatly benefit from this technology, achieving higher productivity and consistent quality in their production processes.
