Description

A Filter For Cutting Oil Refiner Having Multiple Collection Layer Structure

The present invention relates to a filter for a coolant purification device, and more particularly, to a filter for a coolant purification device including a multi-collecting layer structure for collecting metal foreign substances.

Almost all cutting machines such as machining centers (MCT) and CNC (Computerized Numerical Control) lathes use cutting oil to essentially cool the workpiece.

The cutting oil is reused through a refining process after being used in the machining process of the workpiece. Specifically, the cutting oil sprayed to the machining tool or the machining surface for cooling the work includes metal chips and metal foreign substances generated from the work to be cut.

At this time, a coolant purification device is used to filter out metal chips and metal foreign substances floating or mixed in the coolant.

For example, a cutting oil refiner having a configuration as shown in FIG. 1 has been developed.

In the case of the cutting oil refiner shown in FIG. 1, a plurality of filters are mounted therein to perform a corresponding refining operation.

A filter for a coolant purifier with a specific structure is installed in the filter mounting space formed inside the coolant purifier having such a configuration. .

However, in the case of a filter according to the prior art, as a structure for physically filtering out metal foreign substances simply using micropores, there is a problem in that metal particles having a size smaller than that of the micropores cannot be collected.

If the filter's micropores are made smaller in size to collect even fine metal particles, the flow rate of cutting oil passing through the filter is significantly reduced, resulting in a problem that the time required for refining the cutting oil is significantly increased.

Accordingly, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.
