1.Introduction
Metal cutting is a process that is used in the manufacturing of a variety of products. It is the process of removing material from a workpiece, such as a bar, sheet or tube, by using a tool such as a milling machine, drill press or lathe. To perform this process effectively, it is necessary to use a lubricant to reduce heat and friction, as well as extend tool life.
2.Types of Lubricants
There are a variety of lubricants available for use in metal cutting. The type of lubricant chosen depends on the type of cutting that is going to be done. For example, cutting a hard alloy may require a coolant with an extreme pressure (EP) additive, while a softer material may require different lubricants. In addition to the type of lubricant chosen, there are also different methods of applying it.
3.Choice of Lubricant
The choice of lubricant depends on the material being cut and its hardness. Soft materials may require a light duty lubricant, while harder materials require a higher viscosity lubricant. Dry lubricants are also available that can provide additional protection from heat and friction.
4.Considerations
When selecting a lubricant for metal cutting, the following factors should be considered: the type of material being cut, the cutting speed and the necessary lubricant properties. In addition, the cost of the lubricant should also be taken into account. That said, cheaper lubricants may not provide the best performance compared to more expensive lubricants.
5.Benefits
Using a lubricant during metal cutting has a variety of benefits. The lubricant helps to extend the tool’s life by reducing wear and tear. It also helps to reduce friction and heat, which can increase cutting speed and reduce the risk of warping or brittle cutting edges. In addition, lubricants can improve the finish of the cut edges by reducing friction and chatter.
6.Conclusion
Metal cutting requires the use of a suitable lubricant for a number of reasons. The type of lubricant chosen depends on the material being cut and its hardness, as well as the necessary lubricant properties and cost. Using a lubricant during cutting can extend tool life, reduce friction and heat, and improve the finish of the cut edges.
