[Prior Art] * The process of changing the outer dimensions or performance of a machined part by a mechanical twisting type processing machine is divided into cold working and hot working. The so-called cold working is processed at room temperature and does not require a chemical or physical phase change of the workpiece. The hot processing system only adds X to the chemical or phase changes of the workpieces in the county. In L 3, there is a cold addition of butterfly processing force plus I. Because it is a physical direct processing, proper lubrication is required between the workpiece and the processing machine to improve the life of the processing machine, the accuracy of the hole position and the improvement of the hole wall. Roughness, etc. For example, when a workpiece is a printed circuit board, the printed circuit board is generally a flat plate made of a non-conductive material having a pre-drilled hole thereon to mount the wafer and other electronic components. However, when drilling a circuit board, it is easy to see a mechanical break. In view of this, a cushioning material coated with a resin layer on the surface of the shovel was born. The cushioning material is disposed on the printed circuit board and the processing machine. The resin has the function of buffer lubrication and the heat dissipation effect of the name box to reduce the ratio of broken needles. However, the cushioning material is easy to absorb water and is not easy to store. In the drawing process, for example, the aluminum casing of the aluminum electrolytic capacitor is drawn by the aluminum sheet, and the production is recorded because there is no proper lining, which causes the level, or the size of the drawn product cannot be improved. Furthermore, the casing needs to be covered with a hose and heated up to 2 〇 (the temperature around TC so that the hose is heat-shrinked and firmly wrapped on the aluminum casing) for marking, 201107130 In view of the above, the present invention proposes a composite material for mechanical processing lubrication in order to effectively overcome the above problems in view of the above-mentioned shortcomings of the prior art.

Another object of the present invention is to provide a composite material for machining lubrication, the lubricating layer of which can directly serve as a protective layer on the surface of the workpiece. A further object is to provide a mechanically lubricated composite material which can be applied to the machining of drilling, milling and drawing forming. In & for a mechanical force for lubrication of composite materials, the lubricating layer is non-absorbent material, so the reading system is extremely strict, which can avoid the disadvantages of the conventional mechanical plus sliding composite due to the easy absorption of moisture. For the above purposes, the present invention provides a composite for machining and lubricating, comprising a substrate and a lubricating layer on at least a surface of the substrate, the riding layer comprising at least a first mixture layer and a second mixture layer. The first mixture layer is applied to the surface of the substrate and is an anionic aqueous self-emulsification test.
