This site news (correspondent Zhang Geqi reports) Recently, exciting news from the State Intellectual Property Office, the invention patent applied by Zhengzhou Abrasives Grinding Research Institute "200510017879.1 metal bond super hard material grinding wheel centrifugal heat The pressure sintering method and device has been approved and authorized, which is the zero breakthrough achieved by the patent work in the invention patent. The centrifugal hot press sintering method is a very unique superhard material grinding wheel manufacturing process, which is suitable for hot press forming of shaped and high thickness grinding wheels.
At the same time, the “wide-profile diamond grinding wheel forming and dressing device†applied for by the institute has obtained the utility model patent (200820068921.1).
In addition, the applied utility model patent "200820071139.5 Sintering Press Conductive Electrode" will be authorized in the first half of this year.
It is reported that the special equipment research office of the institute has declared four patents for the three designs completed recently, and the application has been accepted by the National Patent Office. The four patent applications include: "200920088045.3 diamond saw blade automatic cold press" utility model, "200920088046.8 new high pressure radial piston pump" utility model, "200920088047.2 six-face presser cylinder differential pressure control system" utility model And "200910064031.2 new high-pressure radial piston pump" invention patent.
