All the Surface grinding series which adopt the V-type guide bring transmission by synchronous belt. Meanwhile, adopt the exceeding precise P4 level ball bearing for spindle, having complete attachment with electro-magnetic chuck or the dense chuck of permanent magnetism and having the following features: operating simple and convenient, low noise, high precision for processing, steady mechanical performance,
