This turning center features a unique back-working turret and pairing R-spindle that
significantly energize the cutting process on the right side of the machine. The availability
of greater variation in simultaneous front-and-back processing speeds up the cycle by
approximately 35% compared to conventional machines with two spindles and one turret.
