Abstract: In a machining sequence a flow of coating fluid is applied, such as through a nozzle, to wet at least the cutting surface of a tool to be engaged with a part to perform a machining operation thereon. The fluid is applied quickly and dried or cured to form an adherent coating layer on the tool. Propylene glycol is an example of a suitable fluid.

This process, and the apparatus performing it, can be incorporated into the machining operation and the tool coating can be refurbished in situ, on a regular basis, before or after a machining operation as appropriate.

Abstract: A cutting insert is provided with a combination coating, comprising a wear-protection coating and an indicating layer. The indicating layer preferably is provided on the tool flank or flanks, meaning for radial inserts on the side surfaces and for tangential inserts on the bottom or top surface.

As a result of the clear color contrast or brightness contrast, used cutting edges can be identified immediately. The use of the tool flanks as indicating surfaces has proven to be particularly advantageous because a tribological and possibly unfavorable coating can be provided, without this having a negative influence on the processing result of the cutting insert.

The alumina layer is also very strongly textured in the [440]-direction. The Al2O3 layer is virtually free of cracks and halogen impurities. Furthermore, the Al2O3 layer gives the cutting edge of the tool an extremely smooth surface finish.

Abstract: The Fiorello Insert is made of a material similar to cratex rubber, and will be used to deburr machined parts while still in the machining cycle. It can also be used to open a bored hole a few tenths of a part or to take off a few tenths of the outside dimension of a part without changing it's contour or shape.

It's more flexible like a piece of rubberized sandpaper being held in your hand that only follows the shape of the material being worked on. This insert will be made to the size and shapes of most standard inserts on the market now, thus eliminating costly tooling needed to be purchased to run this splendid insert. Its shape will be similar to the inserts being used now. Under certain conditions using the smaller Fiorello Inserts, a washer may be used for additional reinforcement when attaching the Fiorello Insert to the tool holder.
