1.Use as highly rigid and accurate machine as possible. 2.If the rpm available is lower than the recommend condition, please reduce the feed rate to the same ratio. 3.Use long shank type please reduce the rpm and feed rate. 4.The Feed and RPM may be changed depending on the M/C conditions ,lubricating and cooling system.
