Low high precision collet type numerical control period of poor grinder ontology and nine components by senior meehanite cast iron FC30 moulds, the artificial normalizing heat treatment, natural aging treatment after more than six months.Processing components adopt YASDA, MITSUI SEIKI, TOSHIBA, ELB world-class equipment such as the clamping process at a time.Precision can reach micron grade, to ensure that the equipment foundation components and high precision. When the machine adopts Taiwan new generation or Japan mitsubishi CNC system, can be done directly through the program with a taper abrasive.Operating procedure is simple and convenient.Grinding out of good stability, workpiece precision compared with traditional
