In the above-mentioned conventional cleaning method using a cleaning device, cleaning oil is jetted simultaneously from all the injection nozzles arranged on the entire outer periphery of the processed product, or the outer periphery of the processed product is swirled for cleaning. Cleaning by spraying oil. Therefore, because the cleaning oil is injected from the outer periphery of the processed product to the processed product for cleaning, the cleaning oil is not directly injected into the deep part of the perforated part or the valley of the threaded part of the processed product, or the perforated part is not sprayed. There is a problem in that the cleaning oils sprayed on the nozzles interfere with each other at a deep portion to reduce the spraying force, and the chips remain in the perforated portion. In particular, the bypass-shaped perforated part (d) of the processed product B (for example, a hydraulic brake component of an automobile) shown in FIG. 5 may have chips remaining since the cleaning oil is not directly projected, and the chips remain as they are. If it is used, it may cause a serious accident such as a brake failure. Therefore, it was necessary to insert a microscope into the hole of the bypass-shaped hole (d) of the washed processed product for inspection. Further, if chips and the like remain as a result of the inspection, it is necessary to wash again and re-inspect, and the cleaning work is an ineffective rate, which is a factor of increasing the production cost.

Further, in order to improve the efficiency of cleaning chips and the like by the cleaning work, high-viscosity cleaning oil may be sprayed at high pressure for cleaning, but since equipment for high pressure is used, the device manufacturing cost is high. Costs such as cleaning oil and electricity will increase. Moreover, since highly viscous cleaning oil easily remains in the perforated portion, it is necessary to remove the cleaning oil through a degreasing process depending on the product, which is a factor that further increases the production cost. The present invention has been proposed in view of the above problems of the prior art, and its object is to completely remove chips and the like by directly injecting a cleaning material to the outside of a processed product or a perforated portion. Accordingly, a cleaning device for processed products is provided which enables highly reliable and efficient cleaning work, saves the cleaning work, and reduces the production cost.
