Benefits of Carbide Cutting Tools
In all machining systems, one simply can not ignore the important role played by tools court. Often, the quality of the finished product would be based on the quality of cutting tools. The quality and performance of cutting tools also directly affect to the overall productivity of a machining system. It is because of its importance that manufacturers take into account several criteria before finally purchasing a piece of tool cutting for machining system. Included in these criteria are the ability of the tools to last a long time in harsh operating conditions and its ability to carry out a very high speed. Also important is the strength of the tool wear, including tensile strength, the edge and the flank wear, cratering or superior wear, chipping, edge contribution (BUE), deformation and thermal cracking.
1. Type of tools
As the demand for better increased cutting tools, cutting tool providers also continuously develop products that can be passed to the demands of manufacturers. Through the years, large amount of material for the manufacture of cutting tools have experienced, some have passed the standards, while others simply retired. Currently, there are only two types of cutting tools heavily favored in the machining industry, high speed steel (HSS) and carbide cutting tools cutting tool, and it seems the carbide cutting tools have slightly exceeded the other in its popularity. So what are the advantages of carbide cutting tools with more than their counterparts HSS? Given his lead in popularity, it is clear that the benefits of carbide cutting tools outnumber that of HSS cutting tools. And we better understand these benefits if carbide know what it is.
2. What is Carbide?
In chemistry, refers to any carbons group of compounds composed of carbon and another element that can be a metal, boron or silicon. There are actually many compounds belonging to this group, among the most popular which includes:
- Calcium Carbide - Aluminum Carbide - Silicon Carbide - Tungsten Carbide - Carbide Iron
3. Industrial uses carbide
In the 20 th century, the carbides have been used for some industrial applications. Carbons used in industrial applications are often called hard metal products are classified into three main categories:
- Use cubed degrees mainly used, guides to the machine and tool
- The degree of impact than shock resistance of carbide products used for dies, in particular for sealing and forming
- Grades tool carbide cutting tools used for cutting
4. Carbide cutting tools
Degrees of the cutting tool of carbides are split into two groups: cast iron-carbide carbides and steel quality. As its name implies, cast-iron carbides are made specifically for cutting materials of cast iron. These carbides are more resistant abrasive wear, the protection of carbide cutting tool from the edge of wear due to the high abrasiveness of cast iron. grade carbide steel for On the contrary, are specially made to resist the formation of craters and the deformation of heat that can be caused by long steel chips at higher cutting speeds. Whatever the degree of carbide is used in a carbide cutting tool, the main carbide material is used in manufacturing tungsten carbide (WC) with a folder cobalt. Tungsten carbide is well known for their toughness and abrasion resistance. Cobalt, however, is used to further harden the surface of the tool.
5. Other variants
Apart from tungsten carbide and cobalt alloy other products are added in the manufacture of carbide cutting tools. Among them is the titanium carbide and tantalum carbide. helps titanium carbide cutting tool carbide to resist the formation of craters, while the carbide tantalum can reduce heat strain in the tool. Also commonly used in the cutting industry today are coated carbide cutting tools. Apart from carbide base materials, titanium carbide, titanium nitride, ceramic tile, diamond coating or titanium carbonitride are used as coating materials. The different coating materials to help carbide cutting tool different, though generally used to further harden the cutting tool.
6. Benefits of Carbide Cutting Tools
- Resistance - superior resistance to abrasion - Superior wear resistance - resistance cratering - The resistance to thermal deformation
- High modulus of elasticity - chemical inertia - resistance to twisting double the HSS - Compressive Strength
