APPLICATION SCOPE：
MBD diamonds are made from selected high-quality diamonds, which are manufactured through processes such as pressing, purifying, drying and selection. Compared with RVD, the crystal is regular, crystal plane is flat, high purity and good pressure resistance.
DETAILS：
According to the different shapes and hardness of crystals, they can be divided into the following types,
| MBD2
The crystal is relatively complete, the surface is smooth, and the compressive strength is low. It is generally used in the production of cutting or polishing soft stone and brittle material processing tools. It can also be used in diamond correction tools.
|
MBD4
Crystal integrity, smooth crystal surface, low compressive strength Tools for cutting or polishing soft stone and brittle materials can also be used in diamond correction knives.
|
|
MBD6 Crystal integrity, smooth surface, moderate compressive strength It is generally used for raw materials such as soft and brittle marble stone cutting drilling tools, but it can not be used for the processing of reinforced concrete tools, it can also be used to make diamond correction tools.
|
MBD8
Crystal is complete, high purity, medium toughness, high thermal stability, strong impact resistance. It is generally used for the production of medium-hard stone processing tools such as granite and marble.
|
|
MBD10 Crystals are complete, high purity, moderate and thermal stability, high impact resistance. For marble, granite, tile and other stone cutting tools processing production.
|
MBD12 Crystal is complete, high purity, strong toughness, high thermal stability, strong impact resistance. Generally used for manufacturing high hardness stone cutting tools, such as reinforced concrete saw blades, geological drills and so on.
|
|
SMD25 The crystal is very complete, is an octahedron, high purity, high compressive strength, high toughness, thermal stability, high impact resistance. Generally used for manufacturing diamond tools with high hardness, such as diamond cutting wire saws, large stone diamond saws, etc. Suitable for the manufacture of various reinforced concrete and engineering geological drilling tools. Various types of diamond modification tools.
|
SMD30 Crystal integrity, positive octahedron, high purity, high compressive strength, high toughness, superior thermal stability and impact resistance Commonly used and manufactured cutting high hardness stone and reinforced concrete diamond tools, electroplating tools, diamond correction knives as well as engineering and geological drills.

Quality Inspection
TI impact toughness: Using the fixed impact number method, the sample is impacted for a certain number of times, then sieved, and the impact toughness is expressed in terms of the percentage of the uncrushed material.
Through the TI test, each batch of abrasive intensity and hardness is controlled within a narrow range, and the larger wave times are reduced to achieve consistent quality.
TTI thermal shock toughness: The pattern is first heated at 1100°C for 10 minutes, and then tested for impact toughness TI. The resulting value is the TTI value.
TTI's main test for heat resistance, thermal stability, is the ability of a crystal to retain its strength after high temperature processing.
Magnetic susceptibility X0: The magnetic susceptibility of diamond is determined by its internal metal impurities, showing a linear relationship. The lower the impurity content, the weaker the magnetism, the higher the strength, the better the crystal form, and the better the thermal stability.
