Co to są wkładki węglikowe?

Czas: 2023-04-07 Trafienia: 35

We usually use knives, graters, scissors, pencil sharpeners, a saw and so on in our daily life for cutting. Do you know how these products are manufactured?

They also are made of cutting tools. These cutting tools share a common property which is that they all change shapes of things by cutting and producing chips.

As we know, cutting tools are tools that cutting things to acquire a desired shape, cutting tools in our daily life cut fruits, vegetables, and wood. But the cutting tools produced by Zhuzhou Lifa cemented carbide industrial co.Ltd cut harder material such as steel, stainless steel, cast iron.

MANUFACTURING PROCESS OF CARBIDE TOOLS

Zobaczmy proces produkcji węglika.

First, mix tungsten carbide with cobalt to make powder which can be classified as raw materials. The granulated mixture is poured into a die cavity and pressed. It gives a moderate strength like that of chalk.

Next, the pressed compacts are placed in a sintering furnace and heated at a temperature of about 1400°Resulting in cemented carbide.

Also, hardness of cemented carbide is at a level between diamond and sapphire and weight is about twice as iron.

The figure on the right shows the condition of a cutting edge during machining. The cutting edge cuts the work piece 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.

Carbide formed into different configurations is the most popular, and they are called indexable inserts. Indexable inserts are used for various shapes of holders and selected according to shape of the workpiece and cutting mode.

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 tool in the photo on the right is a milling tool. 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 frezy palcowe are called milling operations and its main characteristic is that the tools rotate. The machine used for milling is called a milling machine.

The photo on the right 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.

PODSUMOWANIE

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.
