Marubeni Citizen-Cincom Unveils the BNA-42SY5 Lathe at PMTS 2025, Enabling Continuous and Lights-Out Operation!

Marubeni Citizen-Cincom Inc. is redefining precision automation by introducing the BNA-42SY5 lathe at PMTS 2025. Designed for seamless automation, this advanced lathe integrates robotic support directly into the machine’s casting, allowing for efficient and unattended machining operations.

One of the key highlights of the BNA-42SY5 is its 12-station turret with a Y-axis, optimizing versatility in complex machining tasks. The system also includes an advanced part tray stacker, allowing robots to manage up to four trays autonomously. The automatic tray-swapping feature ensures continuous operation by replacing full trays with new ones, minimizing the need for operator intervention and maximizing uptime.

Beyond automation, the BNA-42SY5 is equipped with a precision inspection and sorting system. The robot not only cleans and measures each part before placing it into a tray but also diverts any failed parts to a reject bin, ensuring that only quality-assured components move forward in production. A sample bin feature further enhances process control, allowing operators to request specific parts for manual inspection as needed.

A standout feature of this lathe is its integrated auto-compensation system, which automatically adjusts tooling based on real-time measurements taken at the inspection station. This continuous monitoring and compensation for tool wear ensure that each machined part meets exact tolerances, thereby reducing downtime and maintaining consistent production quality.

With its lights-out operation capability, precision automation, and real-time tool compensation, the BNA-42SY5 lathe is engineered to streamline production, reduce manual intervention, and enhance machining efficiency. Marubeni Citizen-Cincom continues to push the boundaries of smart manufacturing, ensuring that shops achieve higher throughput with uncompromising quality.
