Achieving high-speed high-pressure grinding of PCD! High-speed high-pressure grinding processing.
The substrates such as SiC (silicon carbide), GaN (gallium nitride), and PCD (sintered diamond), which are expected to expand in the market in the future, are difficult materials to process due to their hard and brittle nature. Among them, we would like to introduce a case study that achieved the polishing of sintered diamond, which is particularly challenging to process. [Polishing Results] ■ Surface roughness < 3nm ■ Processing time 4 hours (processing time with conventional methods 10 hours) ■ By using the high-speed high-pressure polishing machine 'EJW-400HSP' and the fixed grinding stone 'MAD Plate', we achieved a reduction in processing time by 6 hours. *For more details, please refer to the PDF document or feel free to contact us.
