Four Corners Pressure Fiber Polishing Machine

GRISH Four Corners Pressure Fiber Polishing Machine is a four-corner pressure optical-fiber polishing machine. The manufacturer describes imported S136 mold steel, dual-motor control, digital timing and precise grinding-process control. Reference specifications include model designation GRS-H-F09, digital timer, imported S136 mold steel and working temperature -10 to +50°C. The manufacturer's source is internally inconsistent: its feature text reports 30–160 rpm whereas the specification table reports 30–180 rpm and separately 160 rpm/revolution; the table states 50 Hz 120 W under Power while Working Voltage lists AC 220 V 40 W. These contradictory speed and power figures are not approved HANS specifications.
