Jäähdytysvoitelu

Jäähdytysvoitelu, often referred to as cutting fluid or coolant, is a crucial element in many machining and metalworking processes. Its primary functions are to cool the workpiece and the cutting tool, reduce friction between them, and flush away chips and debris. This combination of actions significantly improves the efficiency and quality of the machining operation.

The cooling effect prevents the cutting tool from overheating, which can lead to premature wear, reduced sharpness, and potential damage to the workpiece due to thermal expansion. By dissipating heat, jäähdytysvoitelu extends tool life and allows for higher cutting speeds, thereby increasing productivity.

Reducing friction is another key benefit. It minimizes the force required to cut material, leading to a smoother cutting action and a better surface finish on the workpiece. This also contributes to reduced tool wear and energy consumption.

Furthermore, jäähdytysvoitelu acts as a lubricant, preventing the chips from adhering to the cutting tool. It also helps to wash away these chips from the cutting zone, preventing them from interfering with subsequent cuts and potentially causing damage or poor surface quality.

Various types of jäähdytysvoitelu exist, including mineral oil-based, synthetic, and semi-synthetic formulations, each offering different properties and suitability for specific applications. The choice of coolant depends on factors such as the material being machined, the type of cutting operation, and environmental considerations. Proper management and disposal of spent coolant are also important aspects of its use.
