Linear Motion Guideways and Ball screws form one of the critical elements of precision industrial machinery and in latest CNC machines, the speed and accuracy of axis movements required for high speed machining is realized by adopting LM guide technology. Recirculating Ball screws are available in different configurations and accuracy grades. Proper selection and mounting of these elements is crucial for achieving the desired levels of accuracy on modern machine tools.

This programme will address all the relevant aspects of LM guideways & ball screws right from types, selection criteria, mounting procedure supported with case studies.
