Different metal machining methods have different requirements for metal machining fluids. The following are the requirements for metal machining fluids in several major machining methods in the automotive industry:
(1) 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. In particular, when using MAPLAL reamers for machining hard materials, metalworking fluids with good lubricating properties must be used to ensure the surface accuracy of the reaming holes.
(2) Turning and Milling
For the machining of general steel and cast iron materials, the machining methods generally have higher cutting speeds, generate more heat and require sufficient cooling, and can use emulsified and semi-synthetic types of metalworking fluids. Such as my company's RISSSOIL SE226 semi-synthetic type metalworking fluid. RISSSOIL SE204 semi-synthetic metalworking fluid is used for steel and aluminum alloy materials that require high lubricating properties for processing materials.
(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 at the contact area must be reduced to reduce the temperature on the grinding surface. This requires the metal fluid to provide good lubrication performance, and is accompanied by the flushing of large flow metalworking fluid. Heat to meet the grinding precision requirements. The selection of metalworking fluids for grinding processes is relatively complex and requires consideration of a number of factors such as workpiece materials, grinding wheel materials, grinding methods, cutting parameters, and the like. For grinding, RISSSOIL SY304 fully-synthetic metalworking fluid is a good choice based on actual processing conditions.
The above is just a brief introduction of the selection of metalworking fluids under several different common processing methods. Only the more important factors are taken into consideration. In fact, the selection of metalworking fluids needs to consider other relevant factors, such as: metal machining Type; metal material of the workpiece; tool material and type; 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 may include several machining methods. Since various machining methods do not have the same requirements for metal machining fluids, when selecting metal machining fluids, the first consideration should be considered. The metalworking fluid must be able to meet the requirements of the most difficult processing methods on the performance of metalworking fluids, and then secondly consider the requirements of other processing methods on the metalworking fluid to select the appropriate metalworking fluid.
Good metalworking fluids have the following characteristics:
The product effectively prevents the erosion of bacteria and fungi, greatly increases the service life, and saves the cost of storage and maintenance. The product also has good wetting and adhesion properties, reducing the spillage of cutting fluid and also cleaning the environment.
• Product special effects of extreme pressure additives can effectively prevent metal welding and sticking, so that it can protect the surface of the machine and the tool, but also to prevent the tool and knife holder, knife clamp adhesion or bite cards.
After use, the coolant can be easily removed by water, processing solution or aqueous cleaning agent. The user can use the existing technology and equipment, and can dispose of the product according to a common processing method.
The product is compatible with most of the processing materials including: cast iron, steel parts, copper, aluminum alloys, and various plastics and compounds.
Metal cutting fluids have a good balance of cooling performance and lubricating properties. Its low water mist, low foaming properties are ideal for high pressure, high flow coolant systems. The product has a wide range of applications and can be effectively applied in some harsh processing conditions such as: surface machining, centerless grinding, heavy broaching, gear milling, thread milling, etc.
