BNJ42/51

The Miyano BNJ42/51 is a proven twin-spindle CNC lathe built for continuous production of mid-size precision components.

With a heavy-duty frame and box slideways, it provides excellent rigidity and machining stability—essential for Indian workshops seeking reliability and long-term durability in daily operations.

Available in two bar capacities—42 mm and 51 mm—the BNJ series is equipped with two spindles and two turrets, enabling simultaneous front and back machining, a major advantage for reducing idle time and boosting overall productivity.

Each turret supports up to 12 tool stations (with optional rotary tools), and the high-speed indexing ensures quick tool changes. Whether you’re running automotive parts, general engineering components, or fittings, the BNJ42/51 adapts easily to different job requirements. It can machine steel, aluminum, brass, and more, with equal efficiency.

Designed for both mass production and small batch flexibility, this machine fits well in Indian job shops, Tier 1/2 suppliers, and contract manufacturers. With its user-friendly FANUC-based control, low maintenance needs, and automation compatibility (such as bar feeders and part unloaders), the BNJ42/51 delivers high output without unnecessary complexity or operational costs.

It is a solid, cost-effective solution for companies focused on scaling up while maintaining consistent quality.
