CUTTING & FORMING FLUIDS
METAL WORKING FLUIDS
Excellent surface finish, longer tool and die life with minimal coolant consumption, cleaner working environment are some of the desired parameters that directly impact cost per component and productivity levels in metal working processes.
With a number of variables affecting the final finish of the component, role of the coolant/lubricating fluid is critical in achieving higher efficiencies and productivity levels. The basic function of a coolant is to reduce friction between tool and work piece as well as to reduce and dissipate heat in the machining area.
NEED SPECIALITY LUBRICANTS
EXPLORE BECHEM GREASES
Industrial applications operate under intensive conditions such as extreme temperatures, pressures and speeds for extended durations. Greases are expected to provide long life while ensuring minimal friction and wear between the contact surfaces. The grease also has to withstand external factors such as water exposure, dust entry, thermal radiation, contact with corrosive and acidic medium etc. To achieve the desired performance is a feat possible only with high quality speciality lubricants. As one of the earliest firms with expertise in lubricants, BECHEM pioneered the concept of speciality greases and oils back in 1834.
BECHEM’s global range of high performance grease cover the entire spectrum of industrial applications. Designed for critical applications, BECHEM’s special lubricants are recommended in heavy industries such as Steel, Cement, Mining, Power, Paper processing, Railways etc. as well as in vital high-tech sectors such as Automotive, Textile, Food, pharma & beverage processing etc.
LUBRICATING OILS & FLUIDS
BECHEM’s extensive range of specialty oils and metal working fluids for industrial applications and metal working processes are developed with high quality base oils and advanced additive package.

BECHEM offers an extensive range of pastes and speciality aerosols in spray can package for reduction of friction and wear in diverse industrial scenarios such as maintenance and…
BECHEM’s range of Anti-Friction coatings are developed with combination of high quality solid lubricants, organic/in-organic binding agents, solvents and high performance additives. These performance coatings reduce friction and wear with minimal variation in friction values for life lubrication of components.
Frequently Asked Questions
Short bytes for queries on lubricants that always bothered you
Greases are made by mixing a solid material, called a thickener, with a base oil and property enhancing additives; but it’s the oil that forms the lubrication film. For better understanding, grease thickener can be thought of as a sponge saturated with oil. Moving parts squeeze the oil out of the sponge like thickener for forming the lubrication film. Typically, the base oil constitutes the largest proportion of grease weight at about 80-90%, followed by thickener at 10 to 20% and additives under 10%.
Dropping point of a lubricating grease is an indicator of the heat resistance of the grease. and is the temperature at which the grease is no more a thickened lubricating medium. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used.
Few greases have the ability to regain their original structure after cooling down from the dropping point.
The most important feature of a grease is its consistency. A grease that is too stiff may not get pumped into areas requiring lubrication. While a grease that is too fluid may leak out. Grease consistency depends on the type and amount of thickener used and the viscosity of its base oil. A grease consistency is its resistance to deformation by an applied force.
The measure of consistency is called penetration. Penetration depends on whether the consistency has been altered by working. Standard test procedures established by American Society for Testing and Materials International (ASTM) and accepted by industry are ASTM D 217 and D 1403, measure penetration of unworked and worked greases.
The NLGI has established consistency numbers ranging from 000 to 6, corresponding to specified ranges of penetration distance of the standard cone into the test grease. Table below lists the NLGI grease classifications along with a description of the consistency of each classification.
Viscosity: It is a measure of resistance to flow of a lubricating oil.
Viscosity index: It is defined as rate of change of viscosity with respect to temperature.
- It is the most important property which determines the performance of lubricating oils under the influence of temperature
- A lubricating oil should have sufficient viscosity to retain a lubricating film on the surface
- On machine part moving at slow speeds under high pressures, a high viscous oil should be used as it better resists being squeezed out from between the rubbing parts. Light oils can be used for lower pressures and high speeds.
- It is not possible to maintain a liquid oil film between two moving or sliding surfaces if the viscosity is too low and hence excessive wear will occur.
The pour point of an oil is the minimum temperature at which the oil turns into semi solid and almost losses its flow characteristic. At low temperatures, the viscosity of the oil will be very high, causing the oil to resist flow. This is important in equipment that operates in a cold environment or handles cold fluids.
