CUTTING FLUIDS .2. RECYCLING AND CLEAN MACHINING

It is widely recognised by machine tool users that the effect of the c utting fluids on the environment, particularly in regard to their degr adation and ultimate disposal is a major problem. Also because the mac hine tool operator is always in the general area of a cutting fluid, t he effects of contact with the fluid is of primary concern. In additio n to fumes, smoke, bacteria and odours, the fluid can also cause sever e reactions on the skin and various parts of the operator's body. The classification and composition of cutting fluids have been discussed i n part I [1]. While this paper (Part II) addresses the issues of the c lean machining technology mainly recycling and disposal of cutting flu ids.
