The invention relates to an oil mist generator in which the production of oil mist is advantageous.

In general, when machining a workpiece in a machine tool such as lathes, milling, etc., cutting is performed while supplying lubricating oil to the machining site. This is because lubrication, cooling, reduction of friction coefficient, chip removal, and processing surface treatment. Its purpose is largely divided into petroleum oil, soluble cutting oil, mineral oil and fatty oil. These lubricants use differently injected lubricants according to the rotational speed of the tool. Among the lubricants, water-soluble cutting oils having a relatively low viscosity are suitably used at high speed cutting, and high viscosity oil is used at low cutting speed. to be.

However, since the lubricant is injected so that the workpiece and the cutting tool are sufficiently wetted when the cutting tool is rotated, when the cutting tool is rotated at a high speed, the lubricant is rotated together with the cutting tool and scattered to the outside, thereby releasing a large amount of lubricant. There was a problem leaking into.

In addition, in order to supply the lubricating oil injected during the cutting process from the lower part to the upper part, the motor must be driven. Thus, when the motor needs to be driven, the power cost increases due to the motor driving, which is a significant burden on the user. There is a tendency to use a high pressure pump with a higher specification of the coolant pump, and thus the power cost is increasing.

In addition, the use of the lubricating oil, there are a number of problems that occur, in particular, including a lot of problems such as pollution of the working environment due to lubricating oil, expensive waste liquid treatment cost, environmental pollution due to underground infiltration of waste liquid .

The oil mist manufacturing apparatus for cutting, which is my prior patent application No. 10-2002-0036174 (2002.06.27), forms an oil tank for storing oil for generating oil mist, an external atmosphere and a closed inner space. Forming an oil injection nozzle on one side of the inside and provided to rotate by a separate grinding head rotating means, the grinding head is crushed by the oil injected from the oil injection nozzle at a high speed to supply the crushed oil mist to the machine tool An oil pulverization tank having an oil mist outlet for supplying air, an air supply means for injecting oil into the oil pulverization tank at a high speed, increasing the discharge pressure of the oil mist, and introducing high-pressure air for rotating the crushing head; Oil mist supply means for supplying the oil mist generated by grinding in the oil grinding tank to each machine tool Configure together.
