  A The control board is stored inside the machine control panel box.

• Q [Wavy Nozzle 2] [Before installation] Is it possible to set the operation mode without a controller?

  A A controller is required to set the operation mode. It can be set with a wired controller or a wireless controller using an iOS device.

• Q [Wavy Nozzle 2] [Before installation] Is it possible to set the operation mode from NC?

  A No. A controller (wired or wireless connection) is required.

• Q [Wavy Nozzle 2] [Before installation] Can a non-NC machine use Wavy Nozzle?

  A Yes, it can also be controlled by a Sequencer.

• Q [Wavy Nozzle 2] [Before installation] Is there any influence of noise caused by other devices in the factory when connected via Bluetooth?

  A Normally, Bluetooth can communicate over a distance of 20 meters (65 ft), but the it has been verified to be able to communicate if it is 5 meters (16 ft) in a factory noise environment.

• Q [Wavy Nozzle 2] [Before installation] Is there a standard lineup of attachments (mounting jigs)?

  A A standard installation kit is currently available only for FANUC ROBODRILL. However, for other machines that have a track record of installation with MinebeaMitsumi, jigs have been made into drawings and it is possible to buy mounting jigs and obtain drawings.
  We can sell mounting jigs and provide drawings.

• Q [Wavy Nozzle 2] [Before installation] Can Wavy Nozzle use for Semi-dry cut using oil mist?

  A Yes. It can be used.

• Q [Wavy Nozzle 2] [Before installation] What is the maximum viscosity of the cutting-oil?

  A

  We have experience of up to 40mm²/s viscosity.

• Q [Wavy Nozzle 2] [Before installation] What kind of coolant can be used?

  A Wavy Nozzle can be used by oil based coolant WITHOUT chlorine or active sulfer and water based coolant WITH mineral oil.
  If you want to use other kind of oil, please inquire from the form.

• Q [Wavy Nozzle 2] [Before installation] Can Wavy Nozzle eject air instead of coolant?

  A Currently there are two types of nozzles with dia. 3mm and dia. 5mm holes. Since the nozzle is attached by a 1/4 tapered screw, it can be replaced with a commercial nozzle.

• Q [Wavy Nozzle 2] [Before installation] Can Wavy Nozzle use any other liquids besides coolant oil? For example, cleaning solution.

  A Use with liquids other than coolant is not covered by the warranty. However, since some liquids may be usable, please consult with the manufacturer and model number of the liquid.

• Q [Wavy Nozzle 2] [Installation check] Is the M-code signal used to operate Wavy Nozzle a "shot signal" or "Latch Signal"?

  A Latch signal is required.

• Q [Wavy Nozzle 2] [Installation check] Is it possible to change the cable between the ejection unit and the control board to longer cable?

  A No.Operation is guaranteed with the product cable length of 6 meters (20ft). If the cable is extended, it cannot be guaranteed. If the length is not enough, divide the control board and extend it with a cable.

• Q [Wavy Nozzle 2] [Installation check] There are 5 M-code inputs with the standard setting. How can it be expanded up to 31 settings?

  A

  By changing M-Code process mode to "5-BIT", the 31 settings can be called up by combination of 5 codes on a single input line.

  

• Q [Wavy Nozzle 2] [Installation check] KICK mode has a function of oil ejection of one-direction. Does Wavy Nozzle have a built-in valve?

  A No, Wavy Nozzle does not have a valve itself, but it can control the ON/OFF valve signal in the machine.

• Q [Wavy Nozzle 2] [Installation check] How are air and oil connected?

  A An existing nozzle(s) is typically removed and replaced with a Wavy Nozzle unit. An existing or new coolant line would need to attach to the Wavy Nozzle. An adapter may be necessary.

• Q [Wavy Nozzle 2] [Installation check] How to wire Nozzle cable?

  A Nozzle cable is routed using existing holes inside machining area.

• Q [Wavy Nozzle 2] [Installation check] What is the oil inlet of the ejection unit?

  A Rc3/8 female (BSPT)

• Q [Wavy Nozzle 2] [Installation check] Can discharge pressure be adjusted?

  A No. There is no valve or pressure-increasing function inside the Wavy Nozzle, and the pressure of the pump dominates the discharge pressure because it is just a flow path.

• Q [Wavy Nozzle 2] [Installation check] Is there any limitations regarding the mounting direction?

  A There is no limit, as any position/orientation will not affect its ability to operate.

• Q [Wavy Nozzle 2] [Installation check] Can we buy a mounting jig?

  A Standard mounting jigs can be supplied as drawings. They can also be sold (extra cost).

• Q [Wavy Nozzle 2] [Installation check] Can we obtain CAD files to consider installation?

  A Yes, CAD files can be provided.

• Q [Wavy Nozzle 2] [Operation method] Is it necessary to connect the controller even during operation?

  A No. The controller is needed only for setting up the operation mode. Once the setting is complete, there is no problem in operation, even if the controller is removed.

• Q [Wavy Nozzle 2] [Operation method] Is there an alarm signal output that informs the failure of Wavy Nozzle to the machine?

  A Yes. An alarm output terminal is provided on the control board. You can respond by connecting the wiring from the control board to the machine and adding it as an alarm condition or a stop condition. Connection and NC setting is needed.

• Q [Wavy Nozzle 2] [Operation method] Is there the function that notifies the Wavy Nozzle when the machine stops or has an alarm signal?

  A Yes. There is an External alarm input terminal in the control board.

• Q [Wavy Nozzle 2] [Operation method] Is there a case where all coolant is processed only with the Wavy Nozzle?

  A Yes. But, depending on the situation not all processes can be covered with just a single Wavy Nozzle. In that case, please use a fixed nozzle together.

• Q [Wavy Nozzle 2] [Operation method] Are there any variations of the nozzle available?

  A Currently there are two types of nozzles with dia. 3mm and dia. 5mm holes. Since the nozzle is attached by a 1/4 tapered screw, it can be replaced with a commercial nozzle.

• Q [Wavy Nozzle 2] [Operation method] Do chips clog inside Wavy Nozzle?

  A If chips larger than the nozzle diameter enter, they will clog. If clogged, remove the nozzle and blow with air to remove chips.

• Q [Wavy Nozzle 2] [Operation method] Does vibration of the nozzle's movement affect accuracy?

  A From our experience in precision machining at MinebeaMitsumi, it is not a problem as long as the Wavy Nozzle unit is mounted tightly.

• Q [Wavy Nozzle 2] [Operation method] How to troubleshoot error codes?

  A

  Please check the diagnostic chart.

  • Diagnostic chart
  • WN2 Error Code Table

• Q [Wavy Nozzle 2] [Not effective] What is the solution when coolant pressure drops?

  A

  Please clean the filter and coolant tank.

  VIDEO

• Q [Wavy Nozzle 2] [Not effective] Coolant stream is scattered and diffused, and is difficult to spray at the desired cutting point.

  A

  Attach a flow straightening adapter to the nozzle.

  
  

  

  VIDEO

• Q [Wavy Nozzle 2] [Not effective] What is the countermeasure for the limited installation space that prevents injection at the cutting point?

  A

  Install a variable angle nozzle. It increases the range of injection positions.
  

  

  VIDEO

• Q [Wavy Nozzle 2] [Other] What is the difference from the high pressure coolant system?

  A

  High-pressure coolant equipment forcibly breaks chips with high-pressure cutting oil injection of 10 to 20 MPa. The Wavy Nozzle allows the chips to extend and flow in one direction. The chips are not necessarily broken.

  In the following cases, try using a Wavy Nozzle:

  • The operation of the high-pressure coolant pump system vibrates, resulting in deterioration of product accuracy and reduction of machine life.
  • The high-pressure coolant system consumes a large amount of power and generates a lot of oil mist, deteriorating the factory environment and increasing the oil consumption, necessitating the purchase of a mist collector.

Sample

• Q [Wavy Nozzle 2] [Other] Do you have Wavy Nozzle trial units available?

  A Yes, trial units are available. Normally, we ask to confirm the effect within a trial period of about one month. Please contact us if the period needs to be extended.
