Advanced Y-Axis Machining for Complex Parts
This feature makes the BNJ51SY particularly suitable for multi-feature parts where off-center drilling, milling, or grooving is required—all in a single setup.
Ideal for automotive, aerospace, hydraulics, and instrumentation industries in India, the machine supports up to 51 mm bar diameter, making it versatile for mid-sized parts. The dual-turret, dual-spindle configuration allows simultaneous front and back machining, reducing cycle time and improving productivity.
The 12-station turrets allow a wide range of tools, including rotary tools for live operations. The Y-axis, with ±35 mm travel, brings added freedom for angular and offset cuts—reducing reliance on secondary machining processes and improving overall part accuracy.
Built with box-way construction and a strong mechanical base, the BNJ51SY handles demanding materials while maintaining tight tolerances. Its user-friendly programming and robust FANUC control interface help Indian operators transition from basic to complex operations with ease.
If you’re looking for a highly capable turning center that can handle complex geometries without extra setups, the BNJ51SY is a reliable, future-ready addition to your machine shop.
