Summary: Cooling and lubricating cutting tools.

Coolant systems are essential in machining operations to manage the heat generated during the cutting process. This heat buildup can negatively affect both the cutting tool and the workpiece, leading to reduced tool life, dimensional inaccuracies, and poor surface finishes.

Function: Coolant systems deliver a fluid, typically a mixture of water and oil or a synthetic solution, to the cutting zone. This fluid performs several crucial functions:

    Cooling: It absorbs heat from the cutting tool and workpiece, preventing overheating.

    Lubrication: It reduces friction between the tool and workpiece, improving cutting efficiency and tool life.

    Chip removal: It flushes away chips, preventing them from interfering with the cutting process and improving surface finish.

Components: A typical coolant system includes:

    * A reservoir to hold the coolant.

    * A pump to circulate the coolant.

    * Pipes or hoses to deliver the coolant to the cutting zone.

    * Nozzles to direct the coolant stream.

    * Filtration systems to remove chips and contaminants from the coolant.

Importance: Effective coolant systems are vital for:

    * Extending tool life.

    * Improving surface finish.

    * Maintaining dimensional accuracy.

    * Increasing cutting speeds and feed rates.
