Download Technical Data: Grinding Polishing Machine iGrind-844A
Brief Introduction:
The iGrind-844A Automatic Metallographic Sample Grinding and Polishing Machine is a high-precision, fully automated system, equipped with a microprocessor controller, this machine enables stepless speed adjustment for both the grinding/polishing disc and the grinding/polishing head, while allowing intuitive and convenient setting of sample preparation pressure and processing time.
Operators can complete the grinding and polishing steps simply by changing the grinding/polishing disc or the metallographic abrasive papers and polishing cloths, thereby enhancing the machine’s versatility and broad applicability.
The iGrind-844A features freely selectable rotation direction of the grinding polishing disc, quick change disc mounting, center-loaded and single-point loading modes, automatic abrasive delivery (with an optional liquid dispenser), as well as smooth operation, high safety and reliability, low noise levels, and a cast-aluminum base that significantly improves the rigidity of the grinding and polishing process.
