Diamond is extremely hard and has a high melting point. For this reason, it is very useful in cutting tools.
What makes diamond a good cutting tool?
Diamonds are widely used in cutting tools because they are considered to be the hardest element and are able to cut through hard materials. … The main reason why diamond is used for these industrial cutting tools is because of its hardness. Another is its high melting point and durability.
Why diamond is hard and used in cutting tools?
Each carbon atom in diamond lies at the centre of regular tetrahedron. There is no free electron. This tightly bonded arrangement gives a rigid three dimensional structure and due to this, diamond is the hardest substance known and is used for cutting of tools.
What is the use of diamond?
The most familiar uses of diamonds today are as gemstones used for adornment, and as industrial abrasives for cutting hard materials. The markets for gem-grade and industrial-grade diamonds value diamonds differently.
How does Diamond Tool Work?
When used on tools, diamond grinds away material on micro (nano) level. If the tool becomes overheated, the metal bond does not wear away, instead it “glazes over” the diamond. Hence coating or covering the diamond. The metal bond then becomes the cutting agent rather than the diamond.
Is diamond used to cut iron?
Diamond is great cutting tool material, but diamond tools (actually technically PCD tools) cannot cut ferrous metals like Steel or Cast Iron. … If you cut steel with diamond, at higher temperatures (more than 700 deg. C), the Carbon atoms react with Iron to form Iron Carbide (Fe3C).
Can a diamond cut anything?
All of the diamond particles are on the exterior cutting edge of the blade, with no metal-diamond mixture. Depending on the manufacturer’s recommended blade application, vacuum brazed blades will cut a wide variety of material including concrete, masonry, steel, various irons, plastic, tile, wood and glass.
Why are diamonds so important?
The earliest recorded cultures used diamonds to portray strength, the value of love, and even instruments of magic. That value is likely due to a diamond’s natural strength and unique visual appearance in combination with its relative rarity. Even a low-grade gem-quality diamond is still a thing of value and beauty.
Why is a diamond so valuable?
The rarity, difficulties in mining, durability, cut, clarity, color, and carat of diamonds make them expensive and in demand. … Only 30% of the mined diamond stones match the standard gem quality that is required. It is this rarity of stone that makes them the world’s most expensive diamond.
What are the two uses of diamond?
Uses of diamonds are as follows:
- used in ornaments.
- used in glass cutting and rock drilling machines.
- diamond dust is used for polishing other diamonds.
- diamond is used to make windows giving protection from radiation in space and in artificial satellites.
- diamond knives are used in eye surgery.
Why are diamond tools not suitable for machining steels?
They have found that iron atoms reduce the graphitization temperature of diamond, while ferrous metals treated by nitrogen cold plasma increase graphitization temperature during diamond cutting. A multitude of active particles react with the ferrous metal to generate a nitride with a lower chemical affinity to diamond.
What is diamond Machining?
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits.
What kind of diamonds are used in tools?
This quality makes diamond an ideal primary material to cut, grind, shape and polish other hard materials. Diamond tools use both natural industrial diamonds, but more commonly synthetic diamonds.
