CIOE 2021 (The 23rd China International Optoelectronic Exposition), as the world’s leading optoelectronic exhibition, will be held at Shenzhen World Exhibition & Convention Center on September 16-18, 2021. The exhibition focuses on precision optics,chip materials,infrared materials and components and other fields.
More than 3,200 optoelectronic exhibitors will present the entire optoelectronic ecosystem including information and communication, precision optics, sensing, lasers, infrared and photonics.

The first Formnext + PM South China will be held in Shenzhen on September 9-11, 2021. 
EXPO will cover a series of advanced materials, technologies, equipment and products such as materials, powder metallurgy, additive manufacturing and post-processing, bringing new business opportunities to the manufacturing industry in China and even Asia.
Moresuperhard will participate in Formnext + PM South China.​

PCD tool must ensure good cutting edge before machining workpiece. Diamond grinding wheel is the most widely used method. The higher the quality of the cutting edge, the finer the tool mark left at the junction of the geometric reflection region of the workpiece surface, and the higher the surface finish of the workpiece. Because cutting edge collapse or expansion easily cause tool wear or damage, reduce tool life. Edge collapse is a key index of edge quality of diamond tools.

The grain size of diamond grinding wheel should be one point coarser than that of the dressing grinding wheel, and the size of diamond particles should be close to the same, and the shape of diamond particles is approximately spherical. The commonly used particle size is 36# ~100#.

Peripheral Diamond Grinding wheels are used for indexable inserts grinding. Peripheral Diamond Grinding wheels for indexable inserts, must be of a high level of geometrical accuracy, with ability of significant material removal.
Grinding wheel size: D400*W12*X6, W20
Grinding inserts：CBN, SNGA two-edge
Equipment: HI-powerful Peripheral grinding machine HP400 PLUS

iamond powder is mainly used for grinding and polishing, the control of particle size is particularly important. As long as there are oversized coarse particles will cause workpiece scratches so that preceding operation come to naught. So the quality inspection of powder is an important link to ensure the quality of powder products.
