Description

V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a working processing method for applying cutting processing, polishing processing, etc. to a working object, and a mist-like body supplying device used for the same. [Knowledge technology] In the past, when cutting and polishing were performed on a work, in order to cool the heat generated by the collision between the work and the processing tool, the water injection nozzle was extended to the vicinity of the processing point. , Water injection nozzle implementation; Yao water. For example, in a machining center (composite work machine), as shown in FIG. 7, a tool support 2 is mounted on a lower end of a spindle (not shown) in the main body 1, and a tool 3 is connected to the front end of the tool support 2 The processing tool 4 is attached, and an air supply pipe is extended from the main body 1 side toward the processing tool 4. However, in the case of processing such as a large vertical machine such as a cutting machine, it is easy to accumulate water or chips in the processing recess, and sometimes the processing performance is deteriorated. In addition, when a tool made of cemented carbide intermittently collides with a workpiece to perform cutting, the machining point of the cutting edge becomes hot due to heat generation, and is cooled by a pouring liquid at a location other than the machining point. Due to the repeated occurrence of these drastic thermal changes, problems such as chipping (so-called "chipping") or cracks may occur. Therefore, recently, there is also a method in which a liquid is not directly poured, but sprayed into a mist form to give a work piece and a processing tool lubricity. According to this method, although the disadvantage that water accumulates in the recesses does not occur like the way of pouring liquid, or the chipping occurs due to rapid cooling, but on the other hand, if water is used as the atomizing liquid, Insufficient lubricity for work and processing tools, otherwise, if oil is used for atomization

In view of the foregoing circumstances and the use of the mist-like body for deterioration, the present invention can spray compressed air, water, and oil to each part at the same time. When oil and water are mixed, it may not be possible to obtain sufficient Lubricating effect. And the mixture of water and oil in the liquid is not filled, and the parts of the processed surface are given at the same time, because the water and oil are accompanied by compressed air, and the compressed pressure of compressed air, water and oil is fractal, and its purpose is to provide. Work processing gives the device the quality of the liquid that does not impart cooling and lubricating effects. And the injection pressure can be set separately. [Means to Solve the Problem] In order to achieve the foregoing object, the first gist of the present invention is to provide a work processing method, which is characterized in that: when a work is being processed, a plurality of types of liquid are sprayed from a spray nozzle toward the processing section, respectively.
