Cutting Data
* When workpiece materials with high elastic modulus (e.g., stainless steel, heat-resistant stainless steel, high-temperature alloys), it is necessary to increase the number of passes appropriately, with each depth of cut more than 0.08mm, to achieve better thread accuracy and insert life. * To prevent tip chipping during the first cut, a pre-chamfering of C0.3-C0.5 can be applied to the workpiece. * To ensure correct tool alignment and precise thread dimensions during thread machining, perform a preliminary transverse cut with a depth of approximately 0.1mm to confirm tool alignment before starting thread turning.
