Programmable Coolant System “Wavy Nozzle 2” is launched:

A Compact, High Power, Wireless Communications for Realizing an IoT Manufacturing Workplace!

The Mechanical Assembly Business Unit of the Machined Component Manufacturing Headquarters at MINEBEA MITSUMI Inc.(MinebeaMitsumi) has developed a new model of its Wavy Nozzle^® swing coolant^*1 jetting device for removing machining dust and chips with the “Wavy Nozzle 2,” which goes on sale from April 2017.

1. Further enhanced freedom of fixing location due to miniaturization!

By thoroughly reviewing the internal structure, we have succeeded in miniaturizing the size of the jet unit to 49.7% of its previous size, while maintaining the same nozzle performance. This model can now be mounted to machine tools operating in small working areas where mounting of the conventional model would have been difficult.

2. Powered up with double the maximum coolant supply pressure!

The maximum coolant supply pressure has been enhanced from the conventional 2MPa to 4MPa. This means that it is now possible to directly supply coolant from almost any medium-pressure coolant pump device. The next-level in machining dust and chip removal is achieved by combining a stronger coolant jet and nozzle swing.

3. Easy realization of IoT, just by mounting the Wavy Nozzle 2!

Wavy Nozzle 2 does not require use of a conventional wire controller. Just by downloading the dedicated app to your smartphone, it becomes possible to use it as a wireless controller*² for wireless communication with Wavy Nozzle 2. Wireless communications use the Bluetooth Mesh network and by using just one wireless controller unit, it is possible to communicate with up to 50 Wavy Nozzle 2 units. Stable use is possible even within large factories where reception is weak.

Further, with the addition of the new machine monitoring function, an app can monitor the operating situation of machine tools.

^*1 Coolant: Cutting fluid and grinding fluid used to cool and lubricate parts being machined during machining.

^*2Wireless controllers and the dedicated app will be on sale in Japan, U.S.A, Canada, EU countries and in Thailand.
