Developed Of Dedicated Grinding Machine On Plane-Quadratic-Envelope Annular Worm

For the grinding of plane-quadratic-envelope annular worm, we have developed a NC grinder of plane-quadratic-envelope annular worm, because it was rebuilded on Y7520W thread grinder, so they have many disadvantage ,such as ,large shape, poor rigid, precision is difficult to guarantee,operate difficult and so on . On the basis of this, we proposed a new processing technology project of 4-axis linkage of the four. Demonstrated and analysised the new technology in theory, we have proved the consistency of the worm wheel face complete meshing grinding of the plane with the theory of plane-quadratic-envelope annular worm when we used the method of virtual centre 4-axis linkage. the advantages of new technology and feasibility. So we have succeeded rebulided a 4-axis four linkage plane-quadratic-envelope annular worm NC grinder based on CDK6150 CNC lathe.We require further improve and explore through the work for a summary and analysis. CNC Grinder is a complex and unified whole, so many factors impact the processing precision of CNC grinding machines, including grinder own rigidity, the overall accuracy, precision of components and the NC system, servo system accuracy, and the load of servo feed system. Because of the early development of CNC grinder is based on the lathe, its has many disadvantage .Based on the advantages and disadvantages of the use of the grinder in the process, we proposed a new design of dedicated CNC Grinder .Thesis on the design of the mechanical part and security of system of the grind. Based on the theory analysis,this paper focuses on the overall design of NC grinder, including the machine's overall structural design, key parts of the design, and the security of grinder system.
