designed for grinding straight edges or 450 angles on flat glass of different sizes and thickness.Coarse grinding,refine grinding,polishing.and angle-making can be completed in a procession.It��s speed can be widely adjustedby its stelpless regulator. Speed alteration is very mooth.in grinding operation.feeding and operation speed can be adjusted at random. Front rails can be adjusted to fit vanied thickness of processed glass. With an automation system for gripping.lubrication.steady voltage,and its advanced structure,high precision,easy handling,and highefficiency,it is one of indispensable instruments for glass procession.
