When measuring the tool length, please use an internal contact type (non-electricity type) tool setter or a laser type tool setter. Note 2) Effective cutting of stainless steel, titanium alloy and heat-resistant alloy can be achieved with the use of water-soluble cutting fluid. Note 3) Higher feeds and speeds can be used for smaller depth of cut. Note 4) Vibration can still occur if the machine rigidity and clamping method are insufficient. In these cases the feed and speed should be reduced proportionately. I168
