The importance of lubrication in machining mechanical parts


Machining mechanical parts requires enormous attention to detail. Neglecting just one aspect can result in work that does not meet the extremely high demands of this field of industrial activity.

It is necessary to think of everything to achieve results that meet the highest standards, including the lubrication of the workpiece and the cutting machine during the machining process. Find out why below.

The benefits of lubricants during the cutting process

Machinists use lubricant during the production process for many reasons, one of these being the reduction of friction.

Metals produce heat during the high-speed cutting process because the tool rubs against the workpiece, releasing energy in the form of heat. A thermal deformation could occur if either elements were to reach too high a temperature, which can negatively affect the work or damage the equipment. Lubrication decreases the chance of overheating by reducing the rubbing of the elements.

Finally, cutting fluids allow the workpiece to be rinsed and metal chips or filings to be removed more easily during the machining processes. These chips can then be moved to a device designed to collect them. It is crucial that no chips stick to the workpiece, as this could affect machining precision.

The benefits of lubrication for the machined workpiece

Lubrication has benefits for the production process as well as the workpiece. This process makes it possible to modify some of its properties.

For example, some parts are made of materials susceptible to corrosion, but the use of lubricants during production will decrease the likelihood of this process occurring. This results in a longer service life.

Using lubricants to prevent wear on the equipment

Several different types of equipment are used in mechanical parts manufacturing. These will undergo less resistance and a reduced workload if lubricated properly, lowering the risk of premature wear.

Similarly, the risk of damage and the mechanical maintenance necessary for cutting blades will be decreased if they undergo less friction.

The different kinds of machining fluids

There are several different types of machining fluids as they are used in countless machining tasks. They are usually developed by specialists, who can produce them from a variety of products.

For example, they can be produced using mineral oil-type compounds derived from the distillation of petroleum, animal fats or even vegetable oils. These liquids are sometimes nicknamed “soap water” because they have a milky appearance with bubbles on the surface, since water and oil never mix completely.

Machining fluids include:

  • Whole oils
  • Emulsion fluids
  • Micro-emulsion fluids
  • Synthetic fluids

In conclusion

Lubrication provides many advantages and helps avoid problems, making it an essential aspect in the manufacturing of machined mechanical parts.
