Recycling of Metal Cutting Inserts: A Different Approach 2010-01-0273

A large number of metal cutting inserts are used in the manufacturing of automobile parts. These are made from hard metals like Carbide, Ceramic, Cermet, PCD and CBN. Since making of these hard metal inserts involve a high amount of energy in addition to natural resources namely Titanium, Tungsten, Cobalt etc, any attempt made therefore for reusing of the used up inserts will benefit environment because this reuse will lower down the demand on natural resource. Reuse can be done in a number of ways [ 1 ]. Many of these recycling techniques involve removing the dull portion developed during the first use by re sharpening [ 2 ]. A different approach is being suggested here in which used up inserts can be used directly. This approach leads to use of the unused cutting edges /corners of the insert without any re sharpening. Thus the cost of machining becomes half of the original cost or even more depending on the application for reuse.
