Single crystal diamond tools are almost exclusively used for high-precision finishing, which can ensure extremely high dimensional accuracy. PCD and CVD diamond can be used in many of the same processing fields, and PCD is more suitable for rough machining and processing occasions that require high tool fracture toughness. CVD diamond is better at finishing, semi-finishing and continuous turning, and can process more precise workpieces.

PCD tools are most suitable for processing aluminum and other tough non-ferrous alloys (such as copper, brass, and bronze), as well as highly abrasive composite materials (such as graphite, carbon-carbon materials, carbon-added phenolic, glass fiber, and porous seals material).
Single crystal diamond tools are almost exclusively used for high-precision finishing, and their extremely thin cutting capabilities can ensure extremely high dimensional accuracy. PCD and CVD diamond can be used in many of the same machining areas, but PCD is more suitable for rough machining and machining situations that require high tool fracture toughness. CVD diamond is better at finishing, semi-finishing and continuous turning. This is because it has excellent wear resistance and high hardness, and can process more precise workpieces.
(1)The condition of polycrystalline PCD and single crystal diamond under a metallurgical microscope, the lower left picture clearly shows that the edge of the blade will be jagged, while the right picture is smooth and smooth.
PCD under the microscope 100 times:
MCD under the microscope 100 times:
(2) Differences in processing:
PCD tools are composed of many fine crystals, so when turning processing, the surface of the workpiece will also show traces caused by small crystal grains.
MCD cutter can directly present the perfect state of the blade on the workpiece.
Moresuperhard offers resin diamond cutting discs and metal diamond cutting discs specifically for cutting in the glass industry. It can be used to cut glass optical devices such as quartz glass, K9 glass, coated glass, etc. It can also be used to cut various glass tubes, glass spouts, high borosilicate glass tubes, capillary glass tubes, quartz glass, and crystallized glass.
Polyetheretherketone PEEK has excellent comprehensive properties and can replace traditional materials such as metals and ceramics in many special fields. Moresuperhard has developed targeted grinding wheel formulas for the grinding of special engineering plastics such as PEEK, mainly electroplated grinding wheels, divided into rough grinding and fine grinding.
