A coating allows the cutting edge of a tool to cleanly pass through the material without having the material gall (stick) to it. The coating also helps to decrease the temperature associated with the cutting process and increase the life of the tool. The coating is usually deposited via thermal chemical vapor deposition (CVD) and, for certain ...
A disc cutter (also known as a power cutter or a concrete saw) is a specialised, often hand-held, power tool used for cutting hard materials, ceramic tile, metal, concrete, and stone for example. This tool is very similar to an angle grinder, chop saw, or even a die grinder, with the main difference being the cutting disc itself (a circular ...
Typical coating thickness ca. (1 to 7) μm; One commercial coating type used to improve the wear resistance of tungsten carbide tools is the AlTiN-Saturn from Sulzer Metaplas. [6] The coatings are sometimes doped with at least one of the elements carbon, silicon, boron, oxygen and yttrium in order to improve selected properties for specific ...
Cutting tool materials are materials that are used to make cutting tools which are used in machining (drill bits, tool bits, milling cutters, etc.) but not other cutting tools like knives or punches. Cutting tool materials must be harder than the material of the workpiece, even at high temperatures during the process.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
In 1926, Krupp, a German company, developed carbide, a very hard mixture of sintered carbides of various heavy metals, especially tungsten carbide, used for cutting edges and dies. This new material revolutionized metal-removal or “chip-cutting” in manufacturing. In the 1950s, carbide was used in all machining processes except for sawing.
