We developed a system that efficiently machines spindles and housings used across multiple machine models. An Okuma Multus U5000 was integrated with our stocker, enabling continuous operation without the need for changeover. This integrated solution reduced overall footprint and manpower requirements while improving cycle time and operational efficiency. A video showing the Spindle FMC in operation is available below.

Features and benefits
Articulated robot
A flexible, articulated robot is used to handle different types of workpieces. Long tools are stored in the stocker, and the robot is capable to load and unload these tools from the spindle of the Okuma Multus U5000.
Multi stocker
The flexible multi-stocker can handle various shapes, such as spindles and housings.
Automatic workpiece measuring system
Actual measurement of the workpiece is effective at preventing collisions after changeover. Length and diameter of the workpiece are measured with the laser sensor mounted to the robot's hand. Workpiece clamping position is also optimized.
Multi-stocker for long tools
Long tools can be stored in the stocker instead of the machine tool's magazine. This allows long tools to be replaced or inspected during machining, without interrupting the machine's production cycle. A single multitasking machine can preform processes being done with 5 machines.
A single multitasking machine paired with the stocker can handle processes that are normally performed with 5 machines
The reduction in machines allows for a reduction in the number of skilled operators required to run the operation. A single skilled operator is able to manage the system, with a 1/3 reduction in required movement; and an overall improvement in efficiency.
Stocker for different types of workpieces
The stocker and robot system which we incorporated flexible concept are a streamlined system that can handle different types of workpieces. Operators only need to set up daily machining schedule, workpiece and tools, and then move on to next task.
