An Improvement Design Research on the Structure of Precision Grinder


Article Preview

To increase the lower order natural frequency of MM7140 grinder’s support parts is an effective measure to improve structural rigidity, avoid resonance and reduce amplitude. The finite element models of MM7140's lathe bed and column, were established by 3-D software UG, and led into ANSYS for modal analysis. Then, found the column was the weak link based on the modal analysis results, and brought out the more effective improvement program. This paper offers a reliable basis for the design and renovation of MM7140 grinder.
