The square pressure polishing machine strength controlled by four angle, thus the pressure is more precise to control and the final products has higher precision. For pc terminations above 95% could pass 3d interferometer test, while for apc terminations this rate keep 90%. Each polishing jig for this machine is available as lc, sc, st, fc, mtrj, e2000 pc connector as well as angle polishing Made by high quality, hardened steel s136 imported from germany Using the good motors imported (ensuring the movement stable under ultra long time) Using the japanese nsk bearing ( ensuring the internal structure to be stable in the high-speed operation, extending the working life) The electron primary device is imported from omron (ensuring the electrical specification stable) Ferrule diameter: 2.5 mm (0.0984 inch)1.25mm(0.0492 inch).
