The cutting parameters shown in the table are merely a starting guideline The coolant supply is critical for the provision of stable machining condifor general machining. Values should be varied depending on the power or tions and enhanced tool life. A large coolant volume should be supplied, rigidity of the machine to be used. Optimum conditions should be selected especially when drilling diffi cult-to-cut materials. depending on the actual chip control or damage on edges. When drilling stainless steel with low machinability such as austenitic stain- When using the smaller diameter tools in each range, set the feed “f” to the less steel with a depth deeper than L/D = 3, a pecking cycle or internal coollower recommended values. ant supply is recommended.
