Why diamond is used for making cutting tools?

Why diamond is used for making cutting tools?

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.

How is it related to diamond and graphite?

Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are called polymorphs.

Why is diamond used in cutting glass?

Since diamonds are the hardest known substance having hardness set to 10, while glass which are used on windows have a hardness of 5.5. And diamonds being the hardest substance can precisely and accurately cut glass in any desired shape or form.

Which of the following is used for making glass cutters graphite diamond Steel bronze?

Diamond have an extraordinary shining with transparent texture. It is a bad conductor of electricity and very hard in nature It is found in crystal form and have no free electrons. Because of this property it is used for making cutting tools (like glass cutters).

Is graphite used for cutting glass?

Owing to its rigid structure, it can be used as glass cutter. Whereas graphite is a layered structure of carbon atoms and is very soft so, it cannot be used for making cutting tools.

What is diamond used for making cutting tools but graphite is not?

(b) Diamond used for making cutting tools but graphite is not because diamond is a very hard substance and graphite is a soft substance.

Why is graphite used in electrical circuits?

graphite is a good conductor of electricity because there is free electron present in it which help it into pass the electricity. actually there is development of drift velocity when the current is passing through graphite the electron in velocity and result in supply of electricity.

Why graphite is used as lubricant in machines?

The carbon atoms in graphite are sp3 hybridized and are directed in the same plane forming hexagonal rings. The two successive layers are held together by weak forces of attraction, one layer can slip over the other making the graphite soft and a good lubricating agent.

What’s graphite made of?

carbon
graphite, also called plumbago or black lead, mineral consisting of carbon. Graphite has a layered structure that consists of rings of six carbon atoms arranged in widely spaced horizontal sheets.

Why is graphite hard to cut?

Even though graphite can handle intense high-pressure situations with ease, it is actually a very soft, abrasive, and brittle material. This can cause serious challenges when machining, as graphite can eat up cutting tools, and severely minimize a tool’s usable life.

Can graphite milling be done at high speed?

However, because it can be cut at high speed does not mean it should be. Some research shows the higher speed, the longer tool life. However if Vc is too high, the diamond film may fall apart too quickly. Principle 2:Always keep enough feed per tooth Principle 2 is the key point to successful graphite milling.

How to choose the right cutting tool for graphite machining?

When selecting a cutting tool for graphite machining, the coating and cutting edge is the most important consideration. Flute count, helix angles, and other key features of the tool geometry ultimately come second to the coating when purchasing tooling.

What is the best way to conquer graphite?

The only effective way to conquer graphite is using diamond coated tools. Generally, diamond coated tools can last 15-20 times longer then uncoated tools. But it also depends a lot on cutting conditions, machine tools and user requirement of surface quality.
