Dash-kun FAQ

Dash-kun FAQ

Q1 Does the effect change depending on a kind or a manufacturer of water-soluble substance?
A1 No, the effect is nearly unchanged, although the time to remove the odor might be different.
Q2 How long is the guarantee period?
A2 The guarantee period is 1 year.
Q3 How can the foam sprinkler be maintained?
A3 Clean the slit part of the foam sprinkler with brushes once a month.
Q4 How much is the amount of power consumption?
A4 t’s 1.2 yen per hour. It’s about 12 yen if you use 10 hours a day. It’s good moneywise.
Q5 Is it safe?
A5 Yes, it’s safe without any accident such an electric shock, since the parts dipped into the cutting oil do not need electric power
Q6 Why is odor removed?
A6 Because it pumps air (Oxygen) to anaerobic bacteria (The bacteria which release hydrogen sulfide with the odor like an addled egg.) to prevent them from propagating and kill them, and as a secondary effect, it sterilizes them with ultrasound and metal ion generated when the foam bubbles burst, then the odor is removed.
Q7 Is bactericide more efficient?
A7 Bactericide may cause negative effect such as rough and red hands or allergy.
Q8 Is the efficiency of cutting oil changed?
A8 No, the efficiency of cutting oil is not changed, but it can keep the original efficiency, since the quality of the cutting oil becomes good without bacteria by using this unit.
Q9 Is the replacement time of cutting oil changed?
A9 Yes, the replacement time is changed. Water-soluble cutting oil inevitably becomes thick due to reduction of water by dryness, and especially Dash-kun reduces water more than natural drying, since it pumps air. However there is an example that the replacement time doubles, if the concentration is controlled appropriately with adding water.
Q10 Is there any difference due to the quality of processing material?
A10 No, there is no different usage depending on the quality of processing material. However, the operating time might be different, since the generation and strength of odor can depend on the quality of cutting oil.
Q11 How well is the odor removed?
A11 Although the degree of odor is difficult to measure by a measurement instrument, it could be a lifetime of water-soluble cutting oil, if it becomes sticky with being emulsified when using Dash-kun, even it removes odor. Please evaluate whether the cutting oil is really rotten or not by the specific gravity and color. We recommend early setting of this unit and improving the status of odor.
Q12 Is the concentration of cutting oil changed?
A12 Yes, the concentration tends to be high due to water evaporation since dryness is accelerated.
Q13 Is there any effect by prolonged use?
A13 No, there is no effect on machines.
Q14 Is there any problem when using new cutting oil?
A14 No, we recommend using new cutting oil. If this unit is operated during night time when machines are turned off, it exerts an effect sufficiently without being operated during daytime when machines are turned on.
Q15 Does the main unit require maintenance?
A15 No, the main unit itself does not need to be maintained, if the air joint part of and cables this unit are not stepped or cut.
Q16 Why is odor not removed?
A16 Please check the specific gravity and concentration. It exerts almost no effect with completely rotten cutting oil, since it generates odor immediately. Odor can be removed with using this unit after adding water-soluble cutting oil.
Q17 What should be done for the sticky emulsified cutting oil?
A17 Unfortunately, it’s the lifetime of the cutting oil. We recommend changing it. Please clear sludge like machining swarf inside the tank when changing it and then the cutting oil lifetime will extend. Bacteria propagate a lot in sludge.
Q18 What is the size corresponding to this unit?
A18 “n-0150” adapts from 100 liter tank of grinding machine to 200 liter tank like tapping centers of Brother Industries, Ltd. or FANUC ROBODRILL without strong odor. “n-0300” adopts to 400 liter tank. “n-0150w” adapts to two 200 liter tanks or befits to remove odor in a short time with inserting 2 foam sprinklers into 200 liter tank with quite strong odor. “n-0300w” is used for tank larger than 500 liter. It’s effective to use this unit with changing 20% of cutting oil when the odor is quite strong. When it cannot be changed, please use during day and night, although it takes for a while (about 5 days).
Q19 How long does it take to remove odor?
A19 It takes 2-3 days under normal conditions. Although it depends on the degree of odor, a deodorant effect can be seen in 1-6 days if the appropriate unit is used.
Q20 Is it effective to use for new cutting water?
A20 Yes, we strongly recommend using new cutting water. Used in night time while machines are turned off, reproduction of bacteria is prevented enough.
Q21 Is cutting oil bubbled?
A21 No, it’s not bubbled usually, although the more impurities, the more it might be bubbled.
Q22 Is the installation site limited?
A22 Yes, please do not set the foam sprinkler near the circulating pump, as it’s mentioned in the instruction manual. It could throw up sludge accumulated on the bottom.
Q23 How many foam sprinklers can be used for one main unit?
A23 Up to 2 can be used for W types as a standard. If the more foam sprinklers are connected, the pump is overloaded and causes a failure.
