Basics of Coolant Management

Industrial Lubricants are always a vast and interesting subject to discuss and share. Broadly Industrial Lubricants can be discussed in two verticals – one is of course Factory, Plant & Machinery [ FPM ] products like Hydraulics, Gear Oils, Compressor Oils, etc. Another is Lubricants used in processing. In the later segment, one of the most sensitive portfolios is water extendable cutting coolants used in metal processing industries. Many technical publications and in-depth experiences are shared for the maintenance of cutting coolants. However, today's effort is to address the basics of maintenance of Soluble cutting coolants either mineral based conventional high oil content products or new generation semi-synthetic products. Before going into maintenance practices let us have a quick look at the composition and chemistry of Cutting coolants. New generation cutting oils are a complex combination of Lubricity components blended with Emulsifiers, Co-emulsifiers, Corrosion Inhib

Can Lubricants Increase Friction?

  Lubricants like any types of greases & oils usually used to reduce the effect (heat generated when the surface move) of friction or we can say that its decrease the friction between surfaces in mutual contact rather increasing friction. A good lubricants or proper lubrication process does not only reduce friction but also it has multi functional tasks mentioned below. 1st & for most lubricants used to separate or lubricate two moving surfaces. 2nd A good lubricant or if you have selected proper lubrication process then lubricants can be a good sealant & can be used for sealing process. 3rd one of the major role of lubricants is to reduce the heat generated by two moving surfaces in mutual contact. Lubricants can act as coolant. Last but not the least Lubricating oils & greases can also protect material from different types of foreign particles, which can damage the materials like bearing, gears etc. & protects from oxidization and corrosion. To clarify how lubrica

Relation Between Friction, Wear & Lubricants


What is Friction:-

Friction is the resistance to motion and wear is the loss of material as a result of friction, contact fatigue and corrosion. Reducing friction is a key objective of lubrication, but there are many other benefits of this process. Lubricating films can help prevent corrosion by protecting the surface from water and other corrosive substances.

Different Types of Friction:-

Sliding Friction:- 

The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving.

 Rolling Friction:- 

In simple words Rolling friction is the force resisting the motion when a body rolls on a surface.

Also there some more types of friction is there like Boring Friction, Mix of Sliding & Rolling Friction, Internal Friction of a deform-able body. Majorly in all types of application, we can see these types of friction & the main purpose of using lubricant is to reduce these types of frictions in any types of applications.

Different Types of Effects of Friction:-

There are many types of effects we can see due to friction. Below mentioned examples majorly happened due to friction.

1)   Vibrations

2)   Noise

3)   Heat Generations

4)   Wear

5)   Material Transfer

6)   Material Geometry change.

When we are talking about Friction then we must know about the Coefficient of friction.

Co Efficient of Friction:-

A coefficient of friction the minimum force required to get an object to slide on a surface, divided by the forces pressing them together.

Coefficient of friction denotes by µ.

The formula of the coefficient of friction (µ) is = Frictional force / Normal Force.

The coefficient of static friction is just a number that indicates how difficult it is to get surfaces to slide each other. Usually the coefficient of friction between 0 to 1 in most everyday objects & materials. But this does not apply to all situations. There are many cases where the coefficient of friction can be greater than 1. We will discuss this later on. Right now in most of the cases coefficient of friction will be between 0 to 1.

What is Wear:-

In simple words, Wear is a material loss at the friction point.

So, to increase efficiency & service life of any application, We have to reduce the wear & to do this we have to reduce the Coefficient of friction in any manner. If we are able to reduce the coefficient of friction then only we will be able to reduce all types of effects due to friction which is already mentioned in this article and one & only way to reduce it to use a good lubricant.

What is Lubricant?

A lubricant is a substance, usually organic or non-organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. A good lubricant has below mentioned Multi functional Tasks.

1)   To lubricate the two mating surfaces.

2)   To Separate the two mating surfaces

3)   Sealing is also a big working principle of lubricant.

4)   Cooling is one of the most common tasks of a good lubricant.

5)   After all this protection is the utmost priority of a lubricant we use in any types of applications.

6)   Increase the overall efficiency of application.

7)   Enhance cost-effectiveness by reducing energy consumption by increasing overall efficiency.

What is Lubrication:-

In simple words, Lubrication is the control of friction and wear by introducing a friction-reducing film between moving surfaces in contact. Many different substances can be used to lubricate a surface. Oil and grease are the most common & except most commons ones many different types of lubricants are used to reduce friction & wear of two moving surfaces in contact.

You might be interested in knowing that about 2400 BC people use Bitumen, Animal, Vegetable oils as well as water as a lubricant.

Different Types of Lubricants:-

1)   Lubricating Oils.

2)   Lubricating Grease.

3)   Bonded Coatings

4)   Corrosion Inhibitors.

5)   Hydro Lubricants

6)   Lubricant Sprays.

7)   Lubricating Pastes

8)   Lubricating Waxes

9)   Process Lubricants
