Estimating the term…
A method of treatment and processing of tools for machining of workpieces by cutting is described, in particular milling tools. These tools are made up of a high-strength steel, carbide or ceramic, and are provided with at least one cutting flank and a flute, which cutting flank is provided with a cutting edge on the cutting side. In a coating installation, the tool is provided with a first coating which is wear-resistant against abrasion. Afterwards a bevel is ground on each of the cutting edges. A second coating, which is resistant to crater wear, is applied to the ground bevel in a coating installation. Tools are thereby obtained that are characterized by high abrasion resistance and high resistance to wear and tear, in particular during machining of difficult materials at high cutting speed.
A method for treatment and processing of tools for machining of workpieces by cutting, which tools are made up of a high-strength steel, carbide or ceramic, and are provided with at least one cutting flank and a flute, which cutting flank is provided with a cutting edge on the cutting side, wherein in a coating installation the tool is provided with a first coating that is resistant to flank wear, in that afterwards a bevel is ground on each of the cutting edges, which bevel has a rake angle of −5° to −30°, and in a coating installation a second coating is applied on the ground bevel, which coating is resistant to cutting face wear.
