In one processing step requires the use of what kind of cutting fluid, mainly based on the following aspects to consider.
1. Improved cutting performance materials: such as reduced cutting forces and friction, inhibiting BUE and prickly scales in order to reduce the growth of the workpiece surface roughness and improve the dimensional accuracy; reduce the cutting temperature and longer tool life.
2.to improve performance: such as cooling the workpiece, making it easy handling, wash away chips, to avoid filter or pipe blockage; reduce smoke, splash, bubble, no special smell, making the work environment meet health and safety requirements; does not cause the machine and workpiece rust, no damage paint machine; non-perishable, easy to manage, finished on the use of waste water treatment is simple, does not cause skin irritation, harmless to human body.
3. Economic benefits and costs to consider: the costs include the purchase of cutting fluid, supplementary expenses, administrative expenses and improve efficiency, saving costs.
4 regulations, decrees considerations: If the occupational safety and health regulations, fire laws, sewage regulations.
According to the processing method, the workpiece is required to achieve precision, cutting fluid characteristics determine the type of cutting fluid is water-based or oil-based cutting fluid. For example, in the processing emphasize fire safety, you should consider using water-based cutting fluid, cutting fluid is also necessary to consider the emission of waste, waste processing enterprises should have the facilities and take appropriate measures. The grinding process, the cutting speed and the cutting zone temperature is high, generally only use water-based cutting fluid; For machining of carbide cutting tools, generally consider using oil-based cutting fluid. Require the use of manual machine cutting fluid varieties, generally when using the machine if no particular reason it should not be easily changed, so as not to affect the machine's performance. After weighing the conditions in these areas, you can determine the choice of oil-based or water-based cutting fluid. In determining the type of fluid after cutting, according to the processing method, the required accuracy and surface roughness of the workpiece material to be machined project constraints, etc., and lubrication, cooling fluid properties, and so the cutting step selection. Then according to the provisions of the cutting fluid for the selected project can meet the expected requirements for identification, and if there are problems, then back to the company to identify the causes of problems and make improvements, and finally make a clear choice conclusions.
