Introduction to Monocrystalline Diamond (MCD) Tools
Monocrystalline Diamond (MCD) tools, also known as Single Crystal Diamond (SCD) tools, are a type of cutting tool that utilizes a single synthetic diamond crystal. These tools are renowned for their superior performance in certain applications, particularly in non-ferrous materials.
The Composition of MCD Tools
MCD tools are made from a single synthetic diamond crystal, which is similar to a natural diamond. The diamond is yellow-like in appearance and is embedded in a heavy carbide body. This combination of materials gives MCD tools their unique properties.
The Manufacturing Process of MCD Tools
The manufacturing process of MCD tools involves a multi-stage grinding process. High-quality micro-grain carbide is used to provide superior tool life and long-term savings. The grinding process delivers extra sharp, polished edges for burr-free machining, reducing or eliminating the need to hand-finish parts.
The Benefits of Using MCD Tools
Superior Surface Finish
MCD tools are known for their ability to provide an unparalleled finish. They are capable of providing mirrored finishes in brass and aluminum and optically clear finish in polycarbonate and acrylic. The MCD Milling Cutter is particularly effective in achieving these high-quality finishes.
High Cutting Performance
With the proper usage and application, MCD tools can enhance cutting performance, allowing for faster and smoother cuts. This can reduce manufacturing costs for producing tools or machine parts from the MCD cutting tools.
Long Tool Life
Compared to other types of diamond tools, MCD tools have a significantly longer tool life. They can last approximately 3.5-10 times longer than other diamond tools.
Limitations of MCD Tools
Unsuitable for Metal Cutting
MCD tools are not suitable for cutting metals such as iron and CFRP. The heat generated during metal cutting can reach 700-1,000°C, which can melt the MCD and reduce its tool life.
High Manufacturing Cost
While MCD tools have a longer tool life, they also come with a higher manufacturing cost. They are around four times more expensive to manufacture than other types of diamond tools.
Applications of MCD Tools
Industries Using MCD Tools
MCD tools are used in a number of industries where a superior surface finish is required. These include the manufacturing of various soft metals, gold, silver, copper, aluminum alloy, zinc alloy, and non-metallic materials such as acrylic, PVC, PC, and plastic.
Materials Suitable for MCD Tools
MCD tools are particularly effective when used on non-ferrous materials. They can provide excellent surface finishes on materials such as brass, aluminum, polycarbonate, and acrylic.
Maintenance and Care of MCD Tools
Handling and Storage
MCD tools are brittle, and the blade is very sharp, which makes them prone to damage when impacted. They should be handled with care and stored properly to prevent damage to the cutting edge.
Measurement and Inspection
The measurement and inspection of MCD tools should be done using non-contact methods such as optical instruments. This helps to prevent damage to the blade and improve the tool’s life.
Conclusion
Monocrystalline Diamond (MCD) tools offer a range of benefits for certain applications, including superior surface finishes and high-cutting performance. However, they also come with some limitations, such as being unsuitable for metal cutting and having a high manufacturing cost. Proper care and maintenance can help to extend the life of these tools and maximize their performance.
