Classification of metal cutting fluids

The type of cutting fluid oil based (animal oil, vegetable oil, mineral oil), water based (emulsion, micro emulsion, synthetic liquid).

Classification standard

1. International classification standards

The international classification standard ISO 6743/7----1986 has a total of 17 varieties, of which 8 (MHA -- MHH) non-water-melt metal working fluid, 9 (MAA -- MAI) for water-melt metal working fluid, these varieties are suitable for cutting, grinding, electrical discharge machining, thinning rolling, extreme pressure, wire drawing, forging and rolling 44 kinds of different processing conditions.

2, domestic standards

Equivalent in our country adopt ISO 6743/7-1986 made the national standard GB7631.5-89 "the lubricant on the classification of products (L) the fifth part: group M (metal) is given priority to with lubrication requirements of the product is pure oil namely MH (include MHG grease wax MHH soap powder or the mixture of solid lubricants) aqueous solution is given priority to with cooling requirements is that MA class

MH class: oil

L-MHA pure mineral oil is mostly used for heavy duty cutting and honing (for iron powder settlement)

L - MHB fat oil (or oil additive) + mineral oil is mostly used for fine turning screw, hobbing, shaving, drawing pin

L -- MHC inactive extreme pressure cutting oil, mineral oil + inactive extreme pressure additive

L -- MHD active extreme pressure cutting oil, mineral oil + reactive sulfur extreme pressure additive

L -- MHE and L -- MHF compound cutting oil, mineral oil + oil additive and extreme pressure additive

Class MA: water-soluble cutting fluid

L -- MAA antirust emulsion (oil 50 -- 80%)

L -- MAB antirust lubricating emulsion with animal and vegetable fats or long chain fatty acids

L-MAC extreme pressure emulsion contains extreme pressure agent, tapping, broaching and other heavy duty cutting

L-MAD extreme pressure emulsion contains extreme pressure agent, tapping, broaching and other heavy duty cutting

L -- MAE microemulsion (10% -- 30% oil) working fluid emulsified particles below 0.1 micron

L -- MAF Extreme Pressure Emulsion with Extreme Pressure Agent can be used in medium and heavy duty cutting

L -- MAG chemical synthesis cutting fluid

L -- MAH extreme pressure chemical synthesis cutting fluid

L -- MAI grease and paste and water mixture
