Lubrication

A true grease consists of an oil and/or other fluid lubricant that is mixed with a thickener substance to form a solid

has over 1000 patented industrial applications

Cutting fluids are used for certain reasons: keep the workpiece at a stable temperature;maximize the life of the cutting tip by lubricating the working edge; prevent rust on machine parts and cutters

A gas bearing is virtually frictionless, silent, and vibration free

Gas lubrication is applied by a compressed gas being pushed against the surface you wish to be lubricated, this means the surface is "floating" upon a cushion of air which allows it move freely.

Mineral oil is a liquid with a generally high viscosity and can withstand high temperatures

combination of synthetic base oil, thickeners and additives

Graphite forms a lubrication film which provides good wear resistance and good seizure resistance

Graphite is used on systems that use ball bearings, such as skateboards, this is because of its wear resistance

A gas bearing can eliminate the risk of contaminating a process with lubricant

Compressed gases are used in aircraft in some places where hydraulic fluid might contaminate an area. Also compressed gas in the form on pneumatics are used in some earlier planes as a substitute for hydraulics

Mineral

Mineral oil is a lubricant which is derived from crude oil

Cutting Fluids

Cutting fluids are various fluids that are used in machining to cool and lubricate the cutting tool

Cutting fluids can include oils, oil-water emulsions, pastes, gels, and mists

Oil/Grease

a type of shear-thinning fluid

often applied using a grease gun

Graphite

Graphite is a solid lubricant and the layered structure of graphite allows sliding movement

Graphite is dependant on water vapour in the atmosphere, this is because the water is absorbed on to the graphite surface, which reduces the bonding of its structure

Vegetable

vegetable oils and fats

increasingly used in electrical industy

vegetable oils are non toxic to the environment as the biodegrade

have issues with chemical stability

eventually chemically decompose

Compressed Gas

Synthetic

performance advantages over mineral based lubricants

work efficiently in extreme/difficult conditions whether it be because of good viscosity to temperature behaviour

good chemical resistance
