All our processes are based on the requirements of the ISO9001: 2008 management system to establish all relevant documents and records, control product quality in accordance with ISO standards and national GB6966-86 requirements, and are equipped with high-power microscopes, particle morphology analyzers, and laser particle size analysis. Instrument and scanning electron microscope, etc., the particle shape and size distribution and impurity content are strictly tested in accordance with standards. Achieve quality control from raw material supply, production process and final product.

According to customer requirements, we have established different quality standard systems, and set up file tracking to achieve the requirements of "zero quality defects" for products that customers want, and we can produce non-standard products according to customer requirements.

TI(Toughness Index)

The toughness stability of abrasive diamond powder is critical for tools in application. It influences the working efficiency and service life directly. Boreas company persists in consistent quality through toughness testing, to keep the toughness of each batch in a narrow range.

Testing method: Taking some samples to make impact testing, then sieve them, calculate the percentage which remains the original particle, that’s the TI value.

TTi(Thermal Toughness Index)

TTi is the index of heat resistance for superabrasives. The thermal stability of diamond grits is of particular importance in processing since it directly influences on the processing quality, tools life, production efficiency and cost.

Testing method: Putting the samples into the high-temperature sintering furnace by heating in 1100℃ for 10 minutes, then let the samples to do the TI testing, the percentage value is TTI value.

Particle Size Distribution Testing

The size of industrial diamond influences the surface finish of the work piece and grinding efficiency directly during the processing. Boreas company has strict enterprise standards to ensure the consistency of particle size distribution by controlling it into a narrow range.

Testing method: The size testing is used by electroformed sieves. Sieving the samples by two corresponding sieves, calculate the percentage of abrasives in each sieve, the value is particle size distribution.

Micron Powder Size Distribution

As the high-precision material, diamond micro powder will have better performance on the surface finishing quality of work piece if the size distribution can be kept in a narrower range. The theory of the testing is scattering phenomenon, the particle distribution can be calculated by the scattered light to the micro powder.

Testing method: Putting the samples into the testing machine, the analysis software will show the size distribution results.

Magnrtism

The magnetism of synthetic diamond powder is determined by its internal impurity. The less the impurity has, the lower the magnetism, the higher the toughness, the better the particle shape and thermal stability.

Testing method: Putting the abrasives into the test container, the screen of the testing machine will show the magnetism value.

Particle Shape Analyzer

By the means of measuring the particle size and observing the shape by the particle shape analyzer, the particle distribution of mesh diamond powder can be calculated directly under the equivalence principle.

Testing method: Putting the samples under the microscope to analyze the particle size and shape by digital camera and digital image processing technique.
