Now available in the UK from NCMT, the Okuma Spaceturn LB3000 EX II turn-mill centre is equipped with the Japanese manufacturer’s Armroid robotic arm. As a result, the Spaceturn LB3000 EX II is said to be the first in the world with such a feature integrated inside a CNC machine tool.

A trio of different end-of-arm effector options are available for the robot, each one capable of performing different tasks. One is for blasting the cutting zone with air to improve chip management. Another provides additional support during the cutting process to prevent chatter. In combination with a workpiece stacker, the third effector automatically loads and unloads workpieces weighing up to 5 kg. All three are stored within the machine and are changed automatically by the robot.
Although most conventional robotic systems require complex integration and special training for staff, Armroid needs neither. As the robot is part of the machine tool, separate system integration is unnecessary. Using Okuma’s own OSP-P300A control, an operator enters the co-ordinates for the start and finish points. The robot then moves through its motions, with the cycle being generated automatically to avoid collisions. In addition to automated running under program control, manual operation is possible via a pulse handle that micro-positions the arm.
Importantly a longer and more powerful robotic arm, Armroid Type 2, will be integrated into an Okuma Multus B250II multi-tasking lathe for high-mix, small-batch billet work. This arm is capable of handling workpieces up to 10 kg and possesses a fourth end effector with a three-jaw workpiece hand.
