Cooling has a major influence on machining exotic
                                   materials such as Inconel, titanium, Hastelloy, Monel
                                   and other alloys, which are all used in the aerospace
                                   industry. These workpiece materials are difficult to
                                   machine as they have a very high nickel level and
                                   possess a tendency to stick to cutter edges due to their
                                   elastic, sticky and ductile properties - which is one of
                                   the reasons that parts for the aerospace industry are
                                   extremely expensive. Machining these types of materials
                                   without coolant is almost impossible, as the high
                                   temperatures and stickiness cause instantaneous
                                   wear and premature failure for carbide inserts.


                                        Machining these types of

                                      materials without coolant is

                                    almost impossible, as the high

                                     temperatures and stickiness

                                        cause instantaneous wear
                                        and premature failure for

                                                 carbide inserts
