Coolants
coolants play a crucial role in various machining processes to ensure efficient cutting, cooling, and lubrication of
metal workpieces and cutting tools.
Coolants, also known as cutting fluids or lubricants, play a crucial role in machining operations within a fitter
workshop. They are used for various purposes to enhance the machining process, prolong tool life, improve
surface finish, and reduce heat generation. Here’s a demonstration of the various applications of coolants in a
fitter workshop:

Water-Based Coolant:
• Setup: Prepare a machining operation such as milling or turning.
• Demonstration: Use a water-based coolant mixed with water according to the manufacturer’s instructions.
Apply it during the machining process.
Characteristics:
• Water-based coolants are economical and environmentally friendly.
• They provide good cooling properties and are effective in chip removal.
• Water-based coolants are suitable for general machining operations on ferrous and non-ferrous metals.
