3 Functions of A Cutting Fluid

Cutting fluids contribute 3 ways to our machining processes.

Critical to our shops for three reasons.

1) They provide lubrication. Lubrication reduces friction. Reduced friction means less heat. Less heat means better dimensional capability and faster cycle times are possible.

2) They help remove heat. Even though they provide lubrication, some frictional heat is produced. So the ability to capture, and remove heat is an important property of metalworking fluids.

3) They prevent the welding of workpiece material onto the tool.Pressure of the workpiece against the tool and the heat and temperatures involved contribute to the buildup of workpiece material on the tool. Cutting fluids provide an antiweld film to discourage this.
