摘要:
The present invention provides a coated cutting tool comprising a substrate and a surface coating, wherein said coating comprises a Ti(C,N,O) layer comprising at least one columnar fine-grained MTCVD Ti(C,N) layer with an average grain width of 0.05-0.4 µm and an atomic ratio of carbon to the sum of carbon and nitrogen (C/(C+N)) contained in said MTCVD Ti(C,N) layer is in average 0.50-0.65. A method for manufacturing said coated cutting tool comprising depositing the MTCVD Ti(C,N) layer is also provided. The deposition is performed with at least TiCl 4 , CH 3 CN or other nitrile and H 2 as precursors and the grain size of the MTCVD Ti(C,N) layer is controlled by controlling the TiCl 4 / CH 3 CN volume ratio to be within 4-10.

摘要:
A coated cutting tool includes a substrate having a rake side, a clearance side and a cutting edge and a coating comprising a first layer and a second layer. The second layer has a sandwich structure of an inner layer, an intermediate layer and an outer layer, wherein the inner layer is exposed through an opening in the outer layer, the opening extending over at least a portion of the width of the cutting edge. Thereby, a double layer is provided in critical areas, whereas a single layer is provided in other areas. The double oxide layer is an aluminum oxide layer. A method for manufacturing the coated cutting tool is also provided.

摘要:
A cutting insert (100, 200) for cutting, milling or drilling of metal comprises a body having an elongate recess (111, 1111) extending along at least a portion of the body, a first layer (120, 1120) covering interior side walls (112, 113) of the recess, and a sensor arrangement. The body comprises a substrate (110). The sensor arrangement comprises a lead (130, 230, 240) extending along the recess. The lead comprises electrically conductive material which is arranged in the recess such that the first layer is located between the electrically conductive material and the substrate. For at least a depth (D1, D2, D5) below which at least a portion of the electrically conductive material is arranged in the recess, a width (W2, W3, W4) of the recess measured at that depth between portions of the first layer covering opposite interior side walls (112, 113) of the recess is less than or equal to 80 micrometers.
