Influence of High Quality Cutting Fluid On Machining Processes

With the technological progress, high-speed and high-precision, CNC machining has gradually become the mainstream of the processing industry. The improvement of workpiece processing difficulty and accuracy has not only led to the reform of processing technology, but also led to the popularization and rapid development of cutting fluid. In the process of using cutting fluid, we should choose the appropriate cutting fluid according to the performance of the workpiece. At the same time, in order to improve the precision of the workpiece surface, cutting fluid and machine tool performance, the cutting fluid should be maintained or replaced regularly. The influence of high-quality cutting fluid on machining processes is very important.

High Quality Cutting Fluid Improves Cutting Efficiency

High speed machining now means large feed rate and higher spindle speed. Increasing the unit feed rate means the increase of processing load, which requires the processing fluid to have stronger processing (lubrication) capacity and cooling capacity, so as to reduce the heat generation and workpiece deformation in the cutting process and reduce the energy required in the cutting process. This may require high pressure and high flow coolant pumping. Increasing the spindle speed means that the linear speed of the tool or workpiece is increased. In the case of large flow and high pressure pumping, the impact agitation caused will bring more gas into the cutting fluid and produce foaming tendency. The liquid tank design of modern machine tools is becoming more and more compact, and the defoaming time of the processing fluid is becoming shorter and shorter, which poses a new challenge to the anti foaming property and defoaming ability of the processing fluid.

Therefore, the good anti foaming performance and water quality adaptability of high-quality cutting fluid effectively ensure the smooth progress of high-speed cutting. The processing of some auto parts, such as steering gear and crankshaft, requires the use of oily cutting fluid. The high temperature and impact caused by high-speed cutting may atomize the oily cutting fluid. These oil mist floating in the air will affect the operating environment and physical and mental health of the workshop. The dispersion of oil mist also means the loss of oil products. Therefore, in order to prevent this phenomenon, the selection of cutting fluid should be optimized.

Opinions On The Use And Management Of Cutting Fluid

1. The management of coolant is better to be in the charge of a special chemical management company or coolant supplier, so as to liberate yourself from the management of coolant and focus on your core business. If you don’t have the conditions, you’d better designate a special person to be responsible for the management of the coolant.

2. Professional companies help choose the most suitable products.

3. In the later management of use, pay attention to skimming the floating oil, controlling the concentration (testing every day), paying attention to the detection of pH value and microbial content (testing every week and putting bactericide according to the test results), and paying attention to the detection of rust prevention of cutting fluid (testing every week, increasing the detection frequency when the weather is wet).

Through the above management measures, processing enterprises can greatly extend the service life of cutting fluid, reduce the consumption of coolant, reduce the discharge of waste liquid, improve the machining accuracy of workpiece and product qualification rate, and achieve the purpose of improving efficiency, reducing cost and increasing efficiency.
