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 etc. can be achieved with the use of emulsion. Note 3) Chattering can still occur if the machine rigidity and clamping method are insufficient. In these cases the feed and speed should be reduced proportionately. Note 4) When the depth of cut is smaller than shown the revolution and feed rate can be increased. I165
