Mobilmet Alpha, Sigma, Gamma, and Omega

Oil Based Cutting Fluids

Product Description

Mobilmet Alpha, Mobilmet Sigma, Mobilmet Gamma, and Mobilmet Omega are high performance mineral-oil-type active cutting oils incorporating synthesised additive technology. The balanced selection of additives in each Mobilmet cutting oil maximises performance over the wide range of pressures and temperatures encountered when machining difficult metals under difficult conditions. This chemically-synthesised, active additive combination also controls buildup on the tool tip, resulting in a better surface finish.

These Mobilmet cutting oils contain the active anti-weld properties that are required for cutting difficult-to-machine metals. They are transparent on the work piece, allowing good visual inspection of machined parts. These oils, however, can discolour the surface of copper alloys. Mobilmet Alpha, Sigma, Gamma, and Omega are designed for a wide variety of metal cutting operations, severities and metallurgies. They are also formulated for ease of use and operator convenience. These attributes have resulted in these fluids becoming the products of choice for many machine shops.

Mobilmet Alpha cutting oil is the lowest-viscosity product in the series. It is recommended for deep-hole or gun drilling where its low viscosity enables it to flush swarf and chips away from the hole and permits fines to settle quickly. Mobilmet Sigma cutting oil is a medium-viscosity oil that will provide outstanding performance in general-purpose machine operations. It is recommended for nearly all machining operations on ferrous metals, except heavy-duty operations where tolerance and finish are critical, or for operations such as deep-hole drilling where a low-viscosity oil is needed. It is a transparent, low-odor cutting oil that gives outstanding results when compared with other cutting oils in the same viscosity range. Its very high anti-weld and lubricity compounding make it useful on tough, draggy metals. It contains an anti-mist agent. Mobilmet Gamma is a cutting oil with high anti-weld and lubricity compounding. It is recommended for more severe operations, such as heavy-duty threading, tapping, and broaching on difficult-to-machine metals. Where staining is not critical, it may be used on brass, bronze, or other copper-bearing alloys. This anti-mist-type oil is a transparent, low-odor product that provides outstanding performance compared to other so-called heavy-duty cutting oils. Mobilmet Omega is an extremely heavy-duty cutting oil for hard-to-machine metals that must be broached, tapped, or threaded.
