Abstract
The present invention relates to a method of producing metal cutting tools with outstanding performance in terms of toughness, wear resistance and resistance to coating delamination. According to the method the inserts are subjected to a stream of water mixed with blasting media under method conditions that result in an Almén value between 0.5 and 1.
Claims14
A method of making coated tools for metal cutting comprising subjecting an insert to a stream of water mixed with a grit blasting media under conditions that result in an Almén value between 0.5 and 1, wherein the grit blasting media is aluminum oxide, and wherein an average concentration of the grit blasting media is more than 15 vol-% but below 35 vol-%.
A method of making coated tools for metal cutting comprising subjecting an insert to a stream of water mixed with a grit blasting media under conditions that result in an Almén value between 0.5 and 1, wherein the grit blasting media is SiC, and wherein an average concentration of the grit blasting media is more than 15 vol-% but below 35 vol-%.
