BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting chip discharging device for a machine tool, and more particularly, to a cutting chip discharging device for a machine tool, which is capable of smoothly separating and discharging cutting chips and fluids, To a discharge device.

In general, when machining a metal material by using a machine tool, the cutting oil is sprayed on the tool for the purpose of improving the workability, improving the degree of the machined surface, cooling the tool and the machining surface, and ensuring the life of the tool.

These coolants are not used once and discarded but are circulated for a fixed period of time. However, when circulating and supplying the cutting oil, a filtration process for separating the cutting oil from the cutting chip is required.

However, when a large amount of cutting chips are included in the cutting oil during the filtration process, the service life of the cutting oil is not guaranteed and the circulation supply of the cutting oil is not smooth.

In order to prevent such closed ends, a machine tool is provided with a cutting chip discharging device for separating the cutting oil from the cutting chip. This includes a housing, a guide plate provided inside the housing, a screw provided in the center portion of the guide plate in the longitudinal direction, A coolant discharge hole formed on both sides of the guide plate, and a filter plate provided on both sides of the guide plate.

However, in the conventional structure described above, since the guide plate is composed of only one layer and the manure plate is installed on the guide plate, when the cutting chip is conveyed through the rotation of the screw, the cutting chip crosses the manure plate by the rotational force, And the discharge of the cutting oil is not smooth. Further, since the guide plate is filled with the cutting oil without smooth discharge of the cutting oil, the feeding and discharging of the cutting chip is not smooth due to the viscosity of the cutting oil.

On the other hand, a cutting chip generated when a material other than metal such as a non-ferrous metal, aluminum or synthetic resin is machined by using a machine tool is lifted above the water surface of the cooling water when it is transported and discharged by the screw due to the floating nature of the water, There is a problem that the discharge of cooling water is not smooth and the chip is not smoothly transferred and discharged by the screw.

Therefore, there is a technology to improve and supplement the conventional structure in which the working fluid including the cutting oil and the cooling water is not discharged smoothly due to the interruption of the cutting chips generated when the material such as metal, non-ferrous metal, aluminum, need.
