Abstract
If a machine spindle bearing dia. (d) x Max. min-1 (N) of the machine, has a value greater than 1,500,000,then we would class it as a "High Speed Machine", Taking into account the characteristics of modem tooling system, it is evident that conventional tooling system will not allow them to perform at 100% of machine capability. The high speed & hogh precision tooling system must be utilized for higher quality surface finish, extended cutting tool life and reduced machine cycle times.
