What cutting fluid is used for deep hole drilling to machine metal? Please answer

Deep hole drilling (gun drilling) is a new process of deep hole machining developed in recent years. Traditional deep hole machining (hole depth to hole diameter ratio greater than 5), need to drill, boring, rough reaming, grinding and other multi-processes in order to process the hole with high precision and low surface roughness. The new process is the use of special structure of the tool and high-pressure cooling and lubrication system, can be simplified to the above procedures for a continuous tool to complete a considerable depth of high-precision and low-surface roughness of the hole machining, this process is highly efficient, the economic benefits are significant. Excellent performance of deep hole drilling cutting fluid is one of the keys to deep hole drilling machining technology, deep hole drilling cutting fluid must have the following properties: 1) good cooling effect, to eliminate the heat generated by deformation and friction, to inhibit the generation of chip tumors. 2) good high-temperature lubrication, to reduce frictional wear of the cutting edge and support, to ensure that the tool in the high temperature of the cutting zone to maintain a good lubrication. 3) good permeability, Chip removal, so that the cutting fluid can penetrate into the cutting edge in time, and to ensure that the chips can be discharged smoothly. Therefore, deep hole drilling cutting fluid requires high extreme pressure and low viscosity. Great Wall brand high-speed deep hole drilling oil-M0088 by Shanxi Nagel Machine Tool Co., Ltd. more than three years of actual use, product performance in line with the company's production (gun drilling deep hole drilling, single-axis to multi-axis) machine tool lubrication, cooling and other corresponding technical requirements. Recently, Great Wall M0088 high-speed deep hole drilling oil has been successfully written into the OEM manual of the company's machine tool equipment as the designated special oil for drilling, boring and other metal processing processes. With good high-temperature lubrication, cooling and chip removal, it is suitable to be widely used in imported and domestic deep hole drilling machine tools.
