Diamond is well known for its super hardness and strength due to which it becomes an ideal material for cutting tools. Industries have been revolutionized by the use of diamond in cutting tools which has vastly improved precision, efficiency and tool life in many applications. This paper discusses diamond cutting tools in detail, including applications where these are used, their advantages and disadvantages as well as different types of such products available on markets today.
Diamond is one of the hardest naturally occurring materials known to man with a Mohs hardness scale rating of 10/10. Hence it offers extreme resistance to wear & abrasion, coupled with high thermal conductivity aiding heat dissipation during machining processes — key factors contributing towards long-lasting sharp edges on cutting tools while maintaining high efficiency levels throughout prolonged usage periods.
Polycrystalline Diamond (PCD) Tools PCD tools are made by sintering diamond particles with a metallic binder under high pressure and temperature. The tools are very strong and can retain their sharp cutting edge for an extended period. PCD tools are generally used in machining non-ferrous metals, composites, graphite, ceramics, and other abrasive materials. Single-Crystal Diamond Tools Single-crystal diamond tools are manufactured from a single diamond crystal. They provide the highest level of precision and find application in creating ultra-fine finishes; for example, in industries producing electronics and optics. They work very well in cutting non-ferrous metals as well as other soft materials. Diamond-Coated Tools Diamond-coated tools consist of a layer of diamond particles deposited on a substrate, usually carbide. These tools combine the hardness of diamond with the toughness of carbide, making them suitable for a wide range of applications. Including machining hard metals and composites.
In the aerospace industry, diamond cutting tools are used for machining advanced materials like carbon fiber-reinforced polymers (CFRP) and titanium alloys. These materials are challenging to machine due to their hardness and abrasiveness, but diamond tools can handle these tasks efficiently, providing high precision and extended tool life.
The automotive industry benefits from diamond cutting tools in the production of engine components, such as valve seats and piston rings. These components require high precision and durability, which diamond tools can provide. In the electronics industry, diamond tools find large application in the cutting and shaping of materials such as silicon wafers and other semiconductor components. The levels of finish detail and accuracy provided by diamond tools happen to be very critical to electronic device performance and reliability. Diamond tools are applied in woodworking and machining composite materials. Cutting high-pressure laminates (HPL) or medium-density fiberboard (MDF) is particularly abrasive; these materials quickly wear out standard cutting tools. Clean cuts with long tool life make diamond tooling cost-effective for these applications with an advantage in machining productivity also realized as a result. Extended Tool Life One of the major advantages of diamond cutting tools is that they have an extended tool life. Since diamond is hard and wear resistant, such tools can keep their edge much longer than regular tools. This means a reduction in tool change frequency and downtime; it results in increased productivity and cost savings. High Precision and Surface Finish Diamond tools provide high levels of precision as well as fine surface finish, features demanded by applications with very close tolerances and smooth surfaces. Therefore, sectors such as electronics and optics find them extremely useful because even minor irregularities would lead to performance problems in the final product. Reduced Heat Generation Because of the high thermal conductivity of diamond, it aids in dissipating heat produced during cutting processes. This means that there is less risk of thermal damage to the workpiece or the tool, allowing higher cutting speeds and better efficiency.
Diamond cutting tools are not restricted to a small group of materials but can cut a wide variety, including metals, composites, ceramics and non-ferrous materials. This property makes them valuable in numerous sectors from aerospace to woodworking.
Even though diamond cutting tools have many advantages, they also present certain challenges and considerations. The high cost of diamonds tools is one key challenge since such tools are generally more expensive than traditional ones made of steel or carbide.
This is why proper handling and usage is very important for getting the most out of diamond tool life and performance.
The use of diamond cutting tools has really set the pace of industrialization due to the hardness, durability, precision, and unmatched quality that they offer. Applications are found in almost every industry ranging from aerospace, automotive, electronics to woodworking. Although the initial costs are high, better tool life plus extreme precision and versatility make many applications very cost-effective investments. With an increasing level of technology acceptance at different stages of production in manufacturing processes, future use involving diamonds as a cutting tool will certainly enhance workability— alongside efficiency and effectiveness— for modern industries.
