It is one kind of typical integration of machinery product. But present our country engine bed numerical control rate and insufficient 3%, with the US, Japan, Germany and so on developed country also has the very big disparity. The product universal existence quality which processes with the ordinary engine bed is bad, the variety are few, the cost is high, goods supply time long and so on questions, therefore to enhance the product the competitive power, must enhance engine beds numerical control vigorously rate. The numerically-controlled machine tool takes the integration of machinery the typical product, is playing the huge role in the machine manufacture, has solved in well the modern machine manufacture the structure complex, precise, the batch small, the changeable components processing question, and can stabilize the product processing quality, raises the production efficiency large scale. But, the development numerical control technologys biggest barrier is acquires equipments initial investment to be big, this causes many Small and medium-sized enterprises to withstand with difficulty. If eliminates the massive ordinary engine beds, but purchases the expensive numerically-controlled machine tool, will create the huge waste inevitably. Therefore, the ordinary engine beds numerical control transformation has bright prospects. Transforms into the big heterogeneous numerical control grinding wheel engine bed in view of the existing conventional 315 universal lathes, increases the working accuracy, raises the p
