Metal Cutting Tools Role in Industrial World

Metal Cutting Tools Role in Industrial Machine World
Today's world, machineries plays the vital role. Human's life integrates with machineries. Increase the significant of machine operation directs the today's industrial world to new evolution. Main objectives of industrial world are cost-effective manufacture and quality. To achieve these objectives Industrial people need to pay attention in choose the best metal cutting tools. Metal cutting tools are significant one in the machinery manufacture.

About Metal Cutting Tool
Metal cutting tools are typically used to shape the metals to usable forms. Metal cutting tools are indispensable one in machine manufacture process. Metal cutting tool is removing the unwanted material from the work piece metal by cutting action to get required component of machine. Commonly there are two main types in metal cutting process such as orthogonal cutting and oblique cutting. Metal cutting tools can be classified according to various factors cutting edges, motions. According to the cutting edge cutting tools can be classified as single point tools and multi point tools. Single point tools are applied in shaping, plaining, turning and it also used to remove the unwanted metal. Multi point tools such as driller, end milling tools are used in grinding operation. As well as according to the motion it can be differentiated as linear motion tools, rotary motion tools and liner and rotary motion tools.

Characteristics of Metal Cutting Tools Materials
Hi-quality cutting tools should have the characters such as wear resistance, toughness, hardness. So the material used to make the metal cutting tools must have hardness in high temperature, toughness so that tool do not get fracture and wear resistance - long life time. Metal cutting tools are manufactured by various materials such as High Speed Steel, Tungsten Carbide. High speed steel cutting tools are widely applied in various industries. They are drills, reamers, milling cutters & end mills, ground thread taps. Tungsten carbide tools are applied to cutting the diamonds.
Objectives of Metal Cutting Tools
To achieve the economical manufacture, metal cutting tools have some vital features such as high class surface finish, less power consumption, cost-effective tool, quick metal removal, economical in tool replacement and sharpening the tools, minimum deal time of machine tools. Best metal cutting tool must satisfy the above mentioned objectives. So industrial people are pay heed to select the metal cutting tool.

Features of Tungsten Carbide Tools

Cutting tools are defined as a tool designed to cut material or object. Cutting tools are manufactured by various materials like carbide, high speed steal, cobalt alloys, ceramic, cermets, CBN and diamond. Most of the metal cutting tools are manufactured from Carbide. A cutting tool manufactured by carbide material like tungsten, titanium, or tantalum is called carbide cutting tool. Carbide is a binary compound that means consisting of only two elements. Carbide compound mainly have carbon, as well as more electropositive elements or less electronegative elements. Carbide components are hard material and having high heat and wear resistance. Tungsten is one of the carbide materials that has equal amount of carbon and tungsten atom.
Material that is used to make cutting tools must have following characteristics. There are hardness, toughness and wear resistance. Carbide material has all the above characters. Cutting tools are mainly designed to remove the unwanted portion from required one. Cutting tools are used to various kinds of works such as turning, shaping, plaining, milling and drilling. Metal cutting tools are classified as two types. There are single point and multi point. Tungsten cutting tools is multi point metal cutting tool that used in milling and grilling.
Tungsten Carbide Cutting Tools

Tungsten carbide tool is one of the best metal cutting tools, because of its characteristics such as hardness, toughness and scratching resistance. Compare with HSS, Carbide tools have higher temperature resistance. Tungsten carbide tool has sharp cutting edge compare with other tools, so they exactly cut the metal in required shape. And also have capable for cutting more hard metals. High temperature resistance of tungsten carbide tool increase the working speed of tool. As tungsten carbides have high temperature resistance and hardness, most of the manufacturers are using this in their high speed drill bits.
Tungsten carbide tool has long life time because of its hard and temperature resistance character. Tungsten carbide tools are used in both industrial and non-industrial. Tungsten carbide tools are mainly required in milling and drilling. Manufacturers regularly use tungsten carbide tools to cut hard material. However tungsten carbide tools have more features, which is less expensive. Special characters of Tungsten carbide tools are sharp cutting edge, more hardness and high wearing resistance. These are the characters are specify the tungsten carbide tool is best most among the cutting tools.

Metal cutting tools using tungsten carbide and it applications

In previous blog we see about how we choose metal cutting tools and what the types of tools based on the materials. Now this blog we see about tungsten and carbide tools and its applications. The material carbide gives hardness to the material but in the real life, due to the cost of that material it is used with tungsten but in some cases solid carbide tool is inserted in to the part of the tool. It also gives the effectiveness in the metal cutting.

Tungsten carbide cutting tools contain equal parts of tungsten and carbon atoms. Basic form of the tungsten carbide is fine gray powder, after pressing and forging die, it develops as steel that is used for machineries and metal cutting tools.  These types of tools have high abrasive rate, this nature of tungsten carbide is very helpful for cutting metals. Especially rotary tools are made by solid carbide for giving fast in that tools such as milling tools.

Tungsten and Solid carbide tools:
There are many tools are available using solid carbide and tungsten carbide tools, Tips & Inserts, Rounds, Rod, Plug, Flats, Tip Tool as per IS & special, Carbide End mill, Drill, Slot mill, Reamer, Taps, Tipped index able milling cutters & Face mill cutters,  Rotary Burrres cutters, Boring Tool, Parting Tool.

Carbide Tips and Inserts:
Inserts and tips are the small inserts for tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost. Insert tools have ability to cut hard or abrasive materials. To increase the life of carbide inserts, they are sometimes coated. A coating allows the cutting edge of a tool to cleanly pass through the material without having the material gall or stick to it.

Carbide rounds and rods:
Carbide round bars have good abrasive resistance with bending strength, so it is used to make special cutters with various tools.

Carbide plugs and flats:
Plug is used along the die to maintain the Inner bore of the pipe. Plug gages are one such inspection tool that is used for checking and verifying the dimensional accuracy of a hole in a component.

Solid carbide mills and drills:
Carbide mills are used in various milling application in different industries such as general machining, mold and die, power generation and aerospace. Solid carbide drills are used to giving dimensional accuracy and improved finishing surface.

Solid carbide reamers and taps
Solid carbide taps are used to cut alloys and it gives higher removal rate so it gives smoother finishing operations. In this reamer is used to rotator type cutting, mostly the reamers are used to putting the hole.
