There are several manufacturing techniques like bending, deep drawing, drilling, grinding, milling, punching and cutting used for shaping metals. The productivity of any manufacturing process will depend on the tool life and surface integrity of the finished work piece. Therefore, metalworking fluids (MWF’s) are used in the process to reduce tool wear and improve the surface finish of the work piece. This is due to the performance of MWF’s as lubricants, coolants and carriers of the wear debris.
