Methods of Lubrication

In the ITI Turner trade, lubrication is essential for smooth operation of machines and tools. Proper lubrication reduces friction, minimizes wear, and increases the life of machine components. Different methods of lubrication are used depending on the type of machine, speed, load, and operating conditions. This chapter explains the various methods of lubrication in detail.

Introduction to Lubrication

Lubrication is the process of introducing a lubricant between moving surfaces to reduce friction and wear. It also helps in cooling and protecting machine parts.

Need for Lubrication

• Reduces friction and wear
• Prevents overheating
• Protects against corrosion
• Improves efficiency

Methods of Lubrication

1. Hand (Manual) Lubrication

In this method, lubricant is applied manually using an oil can or grease gun.

Uses

• Small machines
• Occasional lubrication points

Advantages

• Simple method
• Low cost

Limitations

• Irregular lubrication
• Depends on operator

2. Drip Feed Lubrication

Lubricant is supplied drop by drop through a lubricator.

Uses

• Light machinery

Advantages

• Controlled supply

3. Wick Feed Lubrication

Lubricant is supplied through a wick by capillary action.

Uses

• Bearings

Advantages

• Continuous lubrication

4. Splash Lubrication

Moving parts dip into lubricant and splash it onto other components.

Uses

• Gearboxes

Advantages

• Automatic lubrication

5. Pressure Lubrication

Lubricant is supplied under pressure using a pump.

Uses

• High-speed machines
• Heavy-duty applications

Advantages

• Reliable and continuous supply
• Efficient cooling

6. Mist Lubrication

Lubricant is supplied in the form of mist.

Uses

• High-speed spindles

Advantages

• Uniform distribution

7. Centralized Lubrication System

Lubricant is supplied to multiple points from a central system.

Uses

• Large machines
• Industrial plants

Advantages

• Efficient and automatic
• Reduces manual work

Comparison of Methods

Factors Affecting Selection

• Machine type
• Speed and load
• Operating conditions

Precautions

• Use correct lubricant
• Maintain proper level
• Avoid contamination

Application in Turner Workshop

In the Turner trade, lubrication methods are used in lathe machines to ensure smooth operation of spindle, gears, and slides. Proper lubrication improves machining efficiency and reduces wear.

Selection of correct method depends on machine requirements.

Importance

• Improves machine life
• Reduces breakdown
• Enhances performance

Conclusion

Different methods of lubrication are used in engineering depending on machine type and operating conditions. Proper lubrication ensures smooth operation and long life of machine components.

Understanding these methods helps in selecting the right lubrication system.

In conclusion, effective lubrication is essential for efficient machining in the ITI Turner trade.
