What is Tungsten Carbide Cutting?
During the process of cutting, Tungsten Carbide is used more as cutting materials for its opitmal performances. Under the different process requirement, the carbide knives would be totally different. The cutting edge cuts the workpiece and chips are produced. The temperature at the top of the cutting edge becomes as high as 800°C because of impact and friction. Cemented carbide grades that can withstand these high temperatures are the most successful.
Different Tools for Carbide Cutting:
1. Lathe Cutting;
External holder and internal boring bar produce round shaped workpieces. Machining processes that use holders or boring bars is called turning, and its main characteristic is that workpieces rotate.The machine used for turning is called a lathe.
2. Milling Tools Cutting;
Milling tools can be divided into two types ; one is face milling which machines the workpiece surface and the other is endmilling which performs slotting shoulder milling etc.. Machining modes that use facemills and endmills are called milling operations, and its main characteristic is that the tools rotate. The machine used for milling is called a milling machine.
3. Drill Tools Cutting
The photo is a tool that produces circular holes in workpieces and is called a drill. Indexable insert type drills and brazed drills produce relatively large holes and solid drills produce smaller holes. The main characteristic of drilling is that it can be used for both milling and turning machines.
As mentioned above, cutting mode is composed of three main styles ; turning, milling, and drilling. By choosing an appropriate cutting tool according to the cutting mode, hard metals can be machined efficiently.
Today cemented carbide tools have become a primary means for increasing metal cutting productivity, while research constantly develops new products for more accurate and faster machining to reduce manufacturing costs.
