Model BNJ-42SY2/51SY2 features a uniquely configured back-working turret and a R-spindle traversable on both X- & Y-axis slides, providing high level of turning operation in a single complete setup from bar stock. The availability of greater variation in simultaneous front-and-back processing with Y-axis control speed up the cutting cycle by approximately 35% compared to conventional machines with two spindles and one turret.
