All machining processes can be completed with a single multitasking machine, resulting in approximately 30% improvement in productivity.
Both high quality and high productivity can be achieved while reducing labor.

When processes are divided between a NC lathe and a machining center, significant time and effort are required for tasks such as dimensional inspection, setup changes, and workpiece cleaning.
With the MULTUS B300Ⅱ (sub-spindle specification), parts that previously required four processes on two separate machines can now be completed in just two processes on a single machine due to the abiltiy to transfer workpieces between spindles. This has eliminated the need to handle work-in-progress workpieces between machines and has improved the overall production flow.
In addition, because there is minimal phase error during transfer, positioning jigs are no longer necessary. Also, issues that occurred during setup changes—such as scratches, dents, and the need to remachine due to size errors—have been drastically reduced.
As a result, we have been able to significantly reduce tasks that were required between processes, resulting in a productivity improvement of approximately 30%. All this is done while maintaining micron-level machining quality.
We have eight MULTUS machines machining parts ranging from ø10 to 50 mm, and every two machines are operated by a single operator.
Even when machining complex parts that require various cutting and drilling operations, the MULTUS can be left unattended for approximately 30 to 60 minutes. During that time, operators can focus on preparing for the next process or conduct quality checks, which helps reduce the workload for operators managing multiple machines.

Precision parts with strict accuracy requirements that only Tamatec can manufacture.
Capable of machining difficult-to-machine materials with high accuracy and ensuring stable production of tight-tolerance parts.

There was a motor shaft job that our competitors had refused because they could not meet its strict accuracy requirements. However, we took the job and were able to succesfully meet the various tolerances that were required for the workpiece.
Also, another difficult component is optical lens barrels. These have strict geometric tolerances, such as keeping a concentricity of ø0.01 for threading from end-to-end of the barrel. If this tolerance is not met, the optical axis of the lens will not align properly and result in a defective product. However, we were easily able to achieve a concentricity of ø0.01.
In addition, the MULTUS B300Ⅱ (sub-spindle specification) features a highly rigid milling spindle, allowing it to machine tough-to-cut materials such as Inconel and titanium alloys with ease. Even at high spindle speeds.
The machine also offers exceptional repeatability, enabling stable machining of precision components with tight tolerances—such as medical device parts—with dimensional accuracy in the 10-micron range.

Even if several machining processes are involved, the 60-tool ATC specification allows optimal tool to be used during each proccess.

All eight MULTUS machines that were installed by 2024 are equipped with a 60-tool ATC specification.
12-turret lathes lack sufficient tooling capacity, requiring the workpiece to be re-clamped during machining—resulting in longer cycle times and reduced machining accuracy.
On the other hand, machining can always be performed using the optimal tool with a 60-tool ATC machine. This enables high-accuracy machining even for parts that require various processes.
In addition, when machining difficult-to-machine materials—where cutting edges wear quickly and frequent tool changes are necessary—the tool life management function allows easy monitoring of each tool’s usage and replacement timing, providing significant support in tool management.(Hiroki Watanabe)
