Bearings and machined with anti-rust oil, metalworking fluids technology Daquan
Properties of the workpiece material is very important for the choice of cutting fluid. According to literature reports, can the material to be processed according to their ease of machinability is divided into different levels, as the basis for selection of cutting fluid. Copper under fixed conditions machinability index is set to 100, it will be cut under the same conditions as other materials, according to the results of the tool relative durability arrayed.
The first set of material: ordinary steel can be cut, including non-alloy steel, low alloy steel and hardened steel (15,35,15CrMn), free cutting steel (Y12, Y12Mn), construction steel (35,60), can be cut coefficient 80;
Material Group II: difficult to cut steel, including high-alloy steel and hardened steel (20CrMo, 42CrMo), high-chromium alloy steel (1Cr17,4Cr13), high chrome-nickel alloy (12CrNi2), acid-resistant, corrosion-resistant chromium-nickel steel (0Cr18Ni9 , 1Cr18Mo10Nb), ??cast steel, may be cutting factor of 50;
Material Group III: difficult to cut steel, nickel and nickel alloys (Ni10Cr10, Ni18Cr20), manganese and nickel silicon (40CrMn2,60Si2Mn), chromium molybdenum steel (20CrMo), silicon (38Si2Mn), titanium and titanium alloys, can be cutting coefficient 25;
Materials Group IV: gray cast iron and malleable member (HT250, KTZ450-06), can be cut coefficient 60 to 110;
Material fifth group: non-ferrous metals, copper and copper alloys (ZCu Sn10Pbl), can be cut coefficient of 100-600;
Material sixth group: light metals, aluminum and magnesium alloys (LF5, LF10, LDI), can be cut coefficient 300-2000.
Index of smaller cutting harder materials processing. In the choice of cutting fluid for machining difficult materials should be selected active high cutting fluid containing anti-wear extreme pressure additives, for ease of processing the material, the choice of pure mineral oil without extreme pressure additives or other cutting fluid.
Cutting is a complex process, although cutting a material change or geometry of the cutting speed when cutting the workpiece changes, the effect of cutting fluid display is completely different, so the choice of cutting fluid processing technology to combine and workpiece the characteristics to be considered.
Clean Metalworking Fluids
Sometimes the obvious things are often overlooked. Metalworking Fluids is one such example, Milacron Co. (Cincinnati, Ohio) of Cimcool technical services department manager Raymond M. Dick said. The effect of processing liquid cleaner than the dirty metalworking fluid better and more lasting. Unfortunately, thoroughly cleaned the tank - the tank a single machine or central system re-add-step process of lubricating oil is a very important - but often overlooked.
