Contact capacity V C, W DC ( ) It is recommended to use each mist spray unit type with the mixing valves, magnet holders, branch pipes and nylon tubes listed in the table below. Mist spray unit This unit, with an oil tank and a spray ON/OFF control unit, sends oil and air to the mixing valve. MU- MU- Mixing valve This valve adjusts the amounts of oil and air from the mist spray unit using built-in oil and air needles, and also discharges oil mist from the nozzle. MV- MV- MV- MV- Magnet holder This magnet holder enables the mixing valve installed on the arm end to be freely attached to the iron and steel parts such as machining tools, etc. MH MH ranch pipe This pipe is used to separate oil and air from the mist spray unit when using several mixing valves. MD- MD- Horizontal machining center Nylon tube This tube is used for the air piping and oil piping between the mist spray unit and the mixing valve.

Number of air needle rotations (turns) Regulator for tank setting for tank Oil level gauge Fixed orifice ubrication plug Oil filler strainer Strainer Working Principle Of the compressed air from the air source, part is directed to the regulator for tank setting (), while the rest is directed to the ON/OFF valve for oil mist (), which operates the ON/OFF valve for the air blow circuit () and the pilot valve for the mixing circuit (). Compressed air at a prescribed setting determined by the regulator for tank setting () passes through the fixed orifice () and gradually fills the oil tank (), applying to the surface. The in the tank passes through the strainer () and is drawn into the pilot valve (). Operating the ON/OFF valve for oil mist () at this point will cause operating signal to be conducted into the pilot valve (), pushing the diaphragm () downwards, and as a result the compressed air from pilot valve () and oil from the opened valve will flow through their respective conduits and be drawn into the mixing valve (). ir and oil are adjusted with varying quantities by the air for mist from the mixing valve () and oil adjustment needles () and (). With dual piping from the mixing valve () to the dual pipe nozzle (), compressed air passes through the outside while oil passes through the inside, and at the tip of the dual pipe nozzle () they are sprayed out as a fine mist by the discharged air. To remove cutting chips, operate the ON/OFF valve for air blow (), which will cause the supplied compressed air to be drawn directly into the mixing valve () and blown out as air through the external piping of the dual pipe nozzle (). To replenish oil, loosen the oil supply plug () to discharge the compressed air from inside the tank through the oil supply plug s side hole. Since it flows gradually from the fixed orifice () into the interior of the tank, it is easy to replenish oil from the oil supply hole. Handling Precautions Mounting. e sure to mount an air filter corresponding to mm (equivalent to the F) on the side of the mist spray unit. djustment. fter loosening the tank s -setting handle (by rotating it to the left), introduce air from the air source. Use the tank s setting handle and set the range from. to. MPa, set each control valve to ON (manual operation or energized), and inspect carefully to make sure there is no looseness in the fittings at each connecting point. t this time, be sure the air and oil adjustment needles of the mixing valve are in a completely closed position (by rotating it to the right.) ubrication. Completely release air in the pipe. Even small amounts of air in the pipe will cause oil to dribble. Fully open the oil adjustment needle of the mixing valve, and turn the ON/OFF valve for oil mist generation to the ON position, or press and hold down the manual button to release all air from inside the pipe. If air buildup from use of branching pipes, etc. takes place inside the pipe, mount an air release valve at the highest position and let the air out. e sure to carry out this operation when replenishing the oil after the oil tank becomes empty.
