Abstract

Replacement of the high value machine tool or special purpose machine tool is not financially feasible and the machine has a large work envelope with high quality and substantial machine components. Slide way grinding machine manufactured by Waldrich Coburg Company in 1994, is a very expensive machine with high precision of work. It’s having a problem of vertical axis falling down by 10-15 mm due to gravitational force at the time of working. The problem is resolved by retrofitting of the worm gear pair by applying theory of self-locking; which is dependent on lead angle of worm gear and coefficient of friction between material of worm shaft and gear. After retrofitting, it’s working very precisely and results obtained are tremendously good. Now vertical axis is working with a very high reliability & accuracy and it doesn’t fall down in any condition.
