Carbide Gear Cutter Made In zhuzhou China
The coating acts as a chemical and thermal barrier, reducing
diffusion and chemical reactions between the tool and the
workpiece, thereby reducing alveolar wear. Coated carbide cutting
tools have the characteristics of high surface hardness, good wear
resistance, stable chemical properties, heat and oxidation
resistance, low friction coefficient and low thermal conductivity,
which can increase the tool life by 3 to 5 times compared with
uncoated tools during cutting. Above, increase the cutting speed by
20%~70%, improve the machining accuracy by 0.5~1 level, and reduce
the tool consumption cost by 20%~50%. Therefore, coated tools have
become the symbol of modern cutting tools, and the proportion of
use in tools has exceeded 50%. At present, various tools used in
cutting processing, including turning tools, boring tools, drills,
reamers, broaches, taps, thread combs, rolling heads, milling
cutters, forming tools, gear hob and gear shapers, etc. Coating
processes can be used to improve their performance.
Practice has proved that a very thin wear-resistant layer is
deposited on the surface of cemented carbide with good toughness,
that is, coated cemented carbide, which can better solve the
contradiction between wear resistance and toughness of cemented
carbide.
