Metal Working Lubricants – A History of Industrial Lubrication
Saturday, August 6th, 2011Lubricants, fluids and coolants regularly utilized in the metal working industry are highly specialised and designed to perform specific tasks. Along with metal forming, metal working features a fairly broad range of tasks – including polishing, cutting, embossing and grinding.
Metal working lubricants can be used for several reasons. While one of the primary functions would be to increase lubrication, they are able to also reduce thermal deformation, improve the overall finish of a metal surface and help to effectively remove loose metal chips from the cutting area.
Lubricants may be used to carry abrasive powders, when used for polishing or lapping of metals. They are effective in serving as a cooling agent when used in grinding applications and in addition they prevent certain materials from sticking to surfaces. Lubricants can help counteract corrosion and rust.
And maybe most of all, the right utilization of metal working lubricants will assist you to reduce deterioration, prolong the life span of tools along with other moving parts, lessen the time allocated to maintenance – and of course ultimately ensure a company’s profitability in the long run.
Different lubricants possess different properties and features. Features that might be important when selecting a lubricant include potential to deal with heat, oxidation inhibiting ability and biodegradable ability. Flash point can also be an essential consideration – the flash point may be the lowest temperature where liquid can emit enough vapours to result in an ignition.
Metal working lubricants are available in three types: greases, fluids and solid lubricants. Each has different properties and may supply most effectively in different industrial applications. Which lubricant to use will depend on several factors – the options associated with a die used, the temperature and the overall processing conditions.
Solid lubricants are chemical substances for example boron nitride and frequently have such qualities to be effective in keeping out moisture, reduce friction and usually reduce wear and tear.
Some industries need specialised lubricants – the transportation, aerospace and automotive industries are the biggest users. The steel forging industry commonly uses graphite based lubricants which is often graphite immersed in oil or water. This type of lubricant also has the advantage of having no fumes and is able to keep the steel forge and area clean.
Lubricants utilized in metalwork vary widely in their chemical composition in addition to their uses. Lubricants may contain such varied ingredients as mineral or petroleum oils, natural oils, waxes or paraffin.
Some lubricants have a high percentage of water and tend to be known in the industry as HWCF – high water content fluids. Synthetic fluids generally offer an effective resistance to heat in addition to excellent cooling abilities; they do not have a petroleum or mineral oil base.
They might not be the most glamorous area of the metal working industry – but certainly, the indispensable lubricant is unquestionably probably the most important.
