Shanghai Machine Tool Works Co., Ltd. has accumulated rich experience in research and development of heavy-duty CNC roll grinders. As the new generation of CNC roll grinders, "MKA84250/15000-H ultra-heavy precision CNC roll grinder" is the largest CNC in the world. Roll grinder. Its characteristic is to replace the traditional roll grinder technology with new patent technology. The product has good versatility and strong competitiveness. Document.write(" ");xno = xno+1; The main innovations of this product have three major aspects: First, the ultra-heavy workpiece drive system developed, which overcomes the key technology of stable driving of heavy-duty workpieces and realizes driving in a top-holding manner. The heavy workpiece runs smoothly and reliably, meeting the requirements of high-precision grinding; the second is the sub-micron grinding wheel micro-feed system developed to achieve high-precision micro-feeding of the grinding wheel frame system during heavy-duty roll surface grinding. The high-precision, high-stiffness grinding wheel frame static pressure spindle meets the requirements of high-efficiency and high-precision grinding; the third is the development of the automatic measuring mechanism, combined with the special roll grinding software, to solve the on-machine measurement problem of large-diameter workpieces, which can realize the roll Fully automatic grinding.
In the aspects of design, optimization and measurement, the roll grinder has applied for 6 invention patents and obtained 3 utility model patents. The machine tool has been tested by the National Machine Tool Quality Supervision and Inspection Center and has been used by the user Shanghai Heavy Machinery Factory Co., Ltd. It is considered that the machine tool has good performance, high processing efficiency and meets user requirements.
"MKA84250/15000-H super heavy-duty precision CNC roll grinder" has been successfully developed, which meets the demand for precision grinding of heavy-duty precision cold-rolled rolls and hot-rolled rolls for the domestic steel industry, and accelerates the steel industry from low-end products to high-end products. The pace of transformation, the realization of precision grinding of wind turbine high-precision spindles and turbine rotors and other key components in the advanced equipment manufacturing industry, as well as the promotion of domestic clean energy development, played a driving role in equipment support.
The super-heavy precision CNC roll grinder project of Shangji Company passed the appraisal of scientific and technological achievements
Committed by Shanghai Machine Tool Works Co., Ltd., one of the major scientific and technological projects of the national high-end CNC machine tools and basic manufacturing equipment jointly developed by Shanghai Jiaotong University and Shanghai University of Technology, “MKA84250/ 15000-H super heavy precision CNC roll grinderâ€, In Shanghai, it successfully passed the appraisal of scientific and technological achievements organized by the China Machinery Industry Federation. The appraisal committee composed of Tan Jianrong, Xu Zhilei, Guo Chongqing and three experts and professors unanimously agreed that this ultra-heavy precision CNC roll grinder with a workpiece of 250 tons can be innovative and has many independent intellectual property rights. It is at the international advanced level, among which it has an international leading level in terms of the maximum weight and processing accuracy of machinable workpieces.
