👉 A tolerance fluid, often used in precision engineering and manufacturing processes, is a specialized liquid medium designed to accommodate and control dimensional tolerances during machining, forming, or assembly operations. It functions by filling gaps between mating parts or components, ensuring smooth movement and reducing friction, which helps maintain precise alignment and dimensional accuracy. This fluid is particularly useful in applications where tight tolerances are critical, such as in the production of microelectronics, aerospace components, and medical devices. By minimizing contact between surfaces, tolerance fluids enhance the efficiency of manufacturing processes and improve the overall quality and reliability of the final products.
