MinebeaMitsumi: Reduces the incidence of defective products to 1/50: Wavy Nozzle
MinebeaMitsumi:
With the movable robot nozzle “Wavy Nozzle”
Incidence rate of defective products in the cutting process,
We succeeded in reducing it to 1/50 of the conventional level.
Movable robot nozzle:
I made use of the idea that goes against the common sense that “machine tool nozzles do not move”.
The removal rate of chips (chips) generated when cutting metal materials has been dramatically improved.
External sales began in earnest three years ago.
Wavy Nozzle:
MinebeaMitsumi’s Wavy Nozzle is used by attaching it to machine tools such as cutting.
The nozzle sways,
Inject cutting fluid into the contact point between the tool and the material,
Guides chips in one direction.
Defective product rate decreased:
In 2013, it was introduced on a trial basis in the manufacturing process of pivot parts.
The defective product incidence rate, which was 1%, has decreased to 0.02%.
Horizontal development for processing other products:
Horizontally deployed for processing other products such as bearings.
Tool life is extended by up to 30% compared to before introduction
The chip removal work after processing was also reduced by about 98%.
Currently, it is installed in more than 2000 cutting machines in Japan and overseas.
Started external sales:
The main body has been reduced in size by half so that it can be mounted on machine tools with a small processing space.
This time, we have started full-scale external sales.
Sales are expected mainly from automobile parts manufacturers.

Programmable coolant systems: Wavy Nozzle – MinebeaMitsumi
Conventional chip-removal methods
typically require injecting coolant at high pressure to blow off the chips.On the other hand, Wavy Nozzle, which “guides” chips,
does not require high pressure coolant, nor does it require a compressor to be installed, thus saving space.
It also contains a feature that allows it to be used for delicate precision machined components,
as produced by MinebeaMitsumi and others, because of its low injection pressure.
Moreover, because of its compact design, the unit does not require special equipment,
and due to its superior versatility, can easily be installed on new or existing machinery.
The intention of the compact design and high versatility was to target chip removal.
However, after initially offering to the market,
MinebeaMitsumi has received
unearthed and unexpected multiple application uses outside of the initial scope from our customers.
