Mono Crystalline Diamond MCD SCD Milling Cutter

Characteristics and Advantages of MCD Material

Monocrystalline Diamond MCD is also called SCD, which means single crystal diamond. It is a single synthetic diamond with a yellow-like crystal.

MCD diamond is a synthesis diamond similar to a natural diamond. However, with the proper usage and application, MCD diamond can enhance cutting tools for high cutting performance to cut faster and smoother. Also, this can reduce manufacturing costs for producing tools or machine parts from the MCD cutting tools.

Application Scope and Limitations of MCD

MCD is unsuitable for metal cutting, such as iron and CFRP, because cutting metal with cutting tools will cause heat of 700-1,000°C, which will melt MCD and reduce its tool life. So mainly used for High-Gloss Mirror Finishing Of Various Soft Metals, Gold, Silver, Copper, Aluminum Alloy, Zinc Alloy And Non-Metallic Materials, Acrylic, Pvc, Pc, Plastic, and Other Materials.

Comparison Between PCD and MCD Tools

Compared to PCD, MCD cutting tools have approximately 3.5-10 times more tool life but around four times more manufacturing cost than MCD tools.

We supply different types of MCD cutters, MCD milling inserts, MCD lathe turning cutters, MCD chamfering cutters, and MCD highlight polishing cutters, also provide customized ones.

Use and maintenance of single crystal diamond tool

• Single crystal diamond tool is brittle, and the blade is very sharp, which is easy to produce the edge to collapse when impacted. Therefore, people should use it under the working conditions of balance and no vibration as far as possible; At the same time, We should improve the rigidity of the workpiece and tool and the rigidity of the whole system as much as possible to increase its vibration resistance.
• Higher cutting speed can reduce the cutting force, while low cutting speed will increase the cutting pressure, thus accelerating the failure of tool blade breakage. Therefore, the cutting rate of the single-crystal diamond tool should not be too low.
• The contact between the single crystal tool and the workpiece or other complex objects should be avoided in the static state to prevent damage to the cutting edge of the instrument and to avoid a shutdown when the tool does not leave the workpiece.
• Diamond knife blade is easy to damage when the edge does not work with a rubber or plastic cap to protect the blade and placed in a separate knife box for storage, each time before use with alcohol to wipe the blade part after work.
• We should take non-contact measurement methods such as optical instruments to detect single crystal diamond tools and use optical devices to see the installation Angle as far as possible during inspection and installation. During testing, copper gaskets or plastic products are put between the tool and the testing instrument to prevent the blade from being damaged and improve the tool’s life.
• Environment (dust particles, dry humidity, etc.); Machine performance stability; The operating proficiency of the staff has an impact on the tool’s life.
• The detection of single crystal diamond tools should use optical instruments and other non-contact measurement methods in the inspection and installation of optical devices as far as possible to detect the installation Angle in the detection of copper gasket or plastic products placed between the tool and the detection instrument, to prevent the blade from being damaged, improve the life of the device.
• Environment (dust particles, dry humidity, etc.); Machine performance stability; The operating proficiency of the staff has an impact on the tool’s life.
