Operations where an object changes shape by the contact of two solid components could be described as a fundamental definition of metal working. When the object changes shape without the loss of material, falls under the category of ‘forming’. The other category of metal working is known as ‘removal’, which results in the loss of material from the object. The third item often included in the process is the lubricant to reduce the friction coefficient between the two solid components, leading to the science and technology that is now known as Tribology.
Metal working fluids are divided into two sectors water miscible metal working fluids and neat oil metal working fluids, as the name indicates one group being based on water the other being water free.
Neat oil metal working fluids are more predominantly used in ‘forming operations’ where a high level of lubrication is required, to leave an enhanced surface finish whilst reducing wear and increasing the life of the tool.
During ‘removal operations’, the rate of cooling is of the upmost importance, to remove the heat from the contact zone, hence the use of water based lubricants, as water has approximately 3 times the specific heat capacity when compared to oil.
