Key Technology Of C8955 Type Shovel Grinder Has Been Studied In The Process Of Transformation Of NC

At present, a large number of general relief grinding machine are used in our country and a lot of shovel grinder has been idle, Spade grinding machine of NC has not been produced in our country, Faced with this problem, C8955-type shovel grinder is used to study in this article and it is used for the transformation of NC.First of all, the principle of C8955-type shovel grinder processing was carried out analysis and research in this article. Steps and methods of C8955-type shovel grinder have been proposed in the process of transformation of NC. Using selected Siemens 840D CNC system, electronic cam is instead of the original mechanical transmission chain, C8955 type shovel grinder linkage question is resolved by the use of electronic cam. Closed-loop system is formed by the grating and the rotary encoder to ensure the machining accuracy. By the principle of the mechanical and kinetic and the requirements of the feed system, the grinding force and ball were calculated, the choice of Screw is resolved. The hob and wheel of the interference problem is studied in the C8955 -type shovel grinder CNC transformation process, the selection of wheel diameter is solved by graphical analysis calculation. According to the principle of C8955-type shovel grinder, analysised and designed of CNC machining process, mathematical model is created, the NC machining program is weaved. Faced with this problem, the machining interface is weaved by VC++ software and selected the Siemens 840D CNC system programming, the relevant parameter of hob is inputted interface by the operator, NC shovel grinder can be automatically processed.After transformation, the C8955 shovel grinder is used for debugging and handling, Machining accuracy and the level of automation of the production equipment has been significantly enhanced and perfect. An operator can control a large number of CNC machine to operate. Reduced the number of operating personnel, labored savings, reduced labor costs. The numerical transformation of machine has high performance and quality, It can continue to use for many years as a new CNC.
