Effect of Grinder Guiding Error on the Machining Precision of Large Scale Surface Workpiece

Abstract:

Nowadays, the demands of large scale surface devices are becoming popular in engineering fields. The grinding process is one of the common methods to achieve the high quality of large scale workpiece. But the final form accuracy of large scale devices is always low. Then it is necessary to analyze the error mechanism of grinding machine on the form accuracy of large scale workpiece. In this paper, the influencing factors of surface grinding machine with horizontal spindle and rectangular table were analyzed firstly. Then the mechanism of guiding accuracy on the surface form accuracy was discussed. It is found that the Z-axis’ guiding accuracy could seriously influence the surface form accuracy. Finally, the face grinding experiment of large scale iron workpiece (420mm×420mm) was performed and the surface form accuracy was measured. The experimental result was in agreement with the theoretical result. It can be concluded that the Z-axis guarding accuracy of grinding machine should be exactly controlled to achieve the high surface precision of large scale device.
