What are the requirements for metalworking fluids in the automotive industry?

1, turning and milling

For the machining of steel and cast iron materials in general, their processing methods generally have higher cutting speeds, generate more heat, and require sufficient cooling. Emulsification and semi-synthetic metalworking fluids can be used.

2, drilling and reaming

These two processing methods have relatively high requirements for the lubricating and cooling performance of metalworking fluids. Generally, the semi-synthetic metalworking fluid containing the extreme pressure additive type with better lubricating properties should be selected to ensure not only its lubricating performance but also good cooling. performance.

3, grinding

Grinding speed is faster, requiring higher cooling and lubricating performance for metalworking fluids. In the grinding process, the friction between the abrasive and the surface of the workpiece must be reduced in the contact area, thereby reducing the temperature on the grinding surface. This requires metalworking fluids to provide good lubricating properties, and accompanied by a gentle flow of high-volume metal processing to remove heat to meet Capricorn's processing accuracy requirements. The selection of metalworking fluids for grinding processes is relatively complex and considers a number of factors such as workpiece materials, grinding wheel materials, grinding methods, cutting parameters, and the like.

The above kinds are just a brief introduction of the selection of several different student number processing methods for metalworking fluids, and only take into account the more important factors, in fact, the selection of metalworking fluids also need to consider other relevant factors, such as: metal Type of machining, metal parts of the workpiece, material and type of tooling, recommendation of the equipment manufacturer, comprehensive cost considerations (including initial costs and maintenance), environmental factors (including safety factors, personnel health factors, etc.)

In the automotive manufacturing industry such as engine and gearbox machining, a CNC machining center can include several machining methods. Since various machining methods do not show exactly the same metal processing fluid, when selecting metal machining fluid performance, first It should be considered that the metalworking fluid must be able to meet the requirements of the most difficult processing methods on the human processing performance, and then consider the need for other processing methods on the metal processing fluid to select the appropriate metalworking fluid.
