Cutting Speeds with HSS. As already mentioned, HSS can in no way compete with Carbide tools when it comes to cutting speeds. Under equally suitable appliions, a carbide tool can cut 4 to 12 times faster than HSS (depending on work material and type of operation) and naturally, the productivity is proportionally high.
The carbides of the group 4, 5 and 6 transition metals (with the exception of chromium) are often described as interstitial compounds. These carbides have metallic properties and are refractory.Some exhibit a range of stoichiometries, e.g. titanium carbide, TiC. Titanium carbide and tungsten carbide are important industrially and are used to coat metals in cutting tools.

Silicon Carbide is an excellent material to use when physical wear is an important consideration because it exhibits good erosion and abrasive resistance, making it useful in a variety of appliions such as spray nozzles, shot blast nozzles and cyclone components.
Although carbide tipped tools use higher quality more costly carbide, the overall cost is usually substantially less than solid carbide tools because only the thick cutting edge is carbide. The body and shank are made from less costly tough hardened tool steel.
Types of abrasive wheels •Silicon carbide. This low-cost wheel works best with non-ferrous metals, such as aluminum, brass, or copper, and carbide. It’s typically dark gray to bronze in color. Although they used to come standard on most bench grinders, they’re becoming less common as more manufacturers switch to aluminum oxide wheels.
steel, and non-metallic material grinding, cutting, or honing. Both green and Black Silicon carbide grinding wheels are used on non-ferrous materials. Differences: Green silicon carbide grinding wheels are typically used on carbides, while black silicon carbide is used on stone, plastics, etc.These wheels can be run with or without coolant.
Boron carbide is used in grit blasting nozzles, high pressure water jet cutter nozzles, scratch and wear resistant coatings, cutting tools and dies, abrasives, and neutron absorber in nuclear reactors. Silicon carbide (SiC) is a compound of silicon metalloid and oxygen. Typically, SiC is used in the alpha silicon carbide structural form.
In the context of machining, a cutting tool or cutter is any tool that is used to remove material from the work piece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, planing and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools.
Jan 31, 2004· Silicon carbide generates too much heat for finish grinding carbide tooling. It micro fractures and flakes the fine corners. Very careful dressing and and inspired touch may result in good free hand ground carbide tools. The problem is, you know what happens to the work if an Acme threading tool flakes in the cut: disaster.
Silicon Carbide grits are commonly either black or green. Black silicon carbide is used to grind non-ferrous metals such as aluminum and brass and also on plastics, rubber, and stone products such as marble and granite. Black silicon carbide is a very sharp grit.
Make Your Own Carbide Lathe Tools: I purchased my lathe second-hand about a year ago. It came with a set of alright traditional tools, but nothing special. Since then, I''ve wanted to try replaceable carbide lathe tools. However, at a price of more than $100 per tool, I couldn''t jus
Jul 02, 2008· Silicon Carbide. Silicon carbide is available in two forms, reaction bonded and sintered. Both materials are ultra hard and have a high thermal conductivity. This has led to silicon carbide being used in bearing and rotary seal appliions where the increased hardness and conductivity improves seal and bearing performance.. Silicon Carbide for Abrasive Appliions
Mar 03, 2006· Major Appliions of Silicon Carbide. There are many uses of Silicon Carbide in different industries. Its physical hardness makes it ideal to be used in abrasive machining processes like grinding, honing, sand blasting and water jet cutting.
Why silicon carbide is use in cutting tools? Certain fish are known to use tools A good few types of are known to use tools Many primates use tools (including man) Certain types of whale

Apr 16, 2009· Rule of thu for grinding is to use a hard wheel for soft materials, and a soft wheel for hard materials, and further dictated by silicon carbide''s ability to dissolve in steels at high temperatures such as found when grinding. While silicon carbide far exceeds the hardness of aluminum oxide, it is not suited to grinding HSS for that reason.
Jan 05, 2010· The power tool industry uses a specialized system of terms to organize and name abrasive grinding wheels and cutting wheels. Like most other power tool accessories, abrasive wheels are available in a huge variety of types and styles suited for different appliions, and most of these types and styles are separated by only small variations in materials and design features.
Silicon carbide is a fast-cutting abrasive commonly used on non-ferrous metals and in low-pressure appliions. Plain hole connectors have a non-threaded hole in the hub of the disc. The disc is attached to the tool with mounting hardware such as a spindle.

Zirconia alumina and silicon carbide blends have a high cut rate and the material grains constantly fracture to produce new sharp edges.
Black wheels are used for grinding cast irons, non-ferrous metals like copper, brass, aluminum, and magnesium, and nonmetallics such as ceramics and gemstones. Green silicon carbide wheels are more friable than the black wheels and used for tool and cutter grinding of cemented carbide.
Silicon Carbide is the highest-quality abrasive in our line - stays sharper and lasts longer than any other abrasive. This abrasive is the favorite for glass etching and heavy automotive parts cleaning due to its high quality and ability to be recycled over and over again.
The heat dissipation objective for most carbide cutting inserts is to get heat into the chip and quickly out of the cut zone. Not so for ceramics, says Mr. Smith. "We set out to generate high temperature ahead of the cutting tool in order to soften or plasticize the workpiece material to facilitate its removal.
