BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chip and an oil mist removing apparatus and method for a lathe machining using air suction in a hollow spindle of a lathe, and more particularly, And an apparatus and a method for removing chips and oil mist using the air suction in the hollow spindle of a lathe, which improves the working environment and improves the cutting efficiency and precision by suctioning oil mist and smoke.

In the lathe machining, the working environment is deteriorated due to the oil mist and smoke generated during the cutting process. In particular, the cutting tool is broken due to the collision phenomenon between the chip and the tool due to the chip, or the chip is rubbed against the surface of the workpiece, Problems such as poor surface roughness occur.

To solve these problems, as disclosed in Korean Utility Model Application No. 20-1998-0047449, generally, a shelf for cutting a workpiece has a storage portion for storing a chip generated by machining the workpiece Respectively.

The chip is continuously taken in the storage portion of the shelf by machining the workpiece. When the operator finishes the operation after repeatedly performing the operation, the chip is removed from the storage portion and removed.

However, in the above-mentioned conventional lathe, when the chip is piled up in the above-mentioned storage part during the operation of the machine, the door is opened while the machine is stopped, and the operator must scrape the chip by using the equipment directly. Of course, in the case of an automatic production line, there is a problem that the entire line is stopped because the chip is removed.

As disclosed in Korean Patent Laid-Open Publication No. 10-2000-0056485, which has been developed to solve the above problems, in a lathe and a tool maker, a high-pressure air pressure is blown in order to quickly discharge and isolate a machining chip, And the like have been developed.

However, these conventional methods are particularly limited in the case of machining the inner part, and the chips are accumulated in the inner workpiece, and even when the high-pressure air or the cutting oil is sprayed, there is a limit in passing the spindle in the long space or discharging it to the front side of the chuck.

On the other hand, in order to solve such a problem in the processing technique, a certain amount of machining is performed, then a cutting operation is stopped and a process of removing the chip is added in the middle. However, .

In addition, according to Korean Patent Laid-Open No. 10-2008-0067534 for removing oil mist generated in a machine tool, oil mist is positively (+) and reversibly -), discharging the oil mist from the air by an inertial impact force generated by forcibly rotating the air, and discharging air through the fan.

However, the above-described apparatuses and methods have a problem in that a complicated structure causes high cost and careful maintenance is required.
