L/D = 5). More than Low speed may cause chattering (2) Even minor workpiece run-out may affect tool life. Spindle speed n 2,000min-1 and chipping on the cutting edge. (3) Select a boring bar with a diameter closest to the bore diameter. Excessive depth of cut may cause (4) Although it is difficult to increase the rotational speed in Depth of cut ap 0.03 to 0.2mm larger tool deformation resulting in small diameter boring applications, higher speeds are deterioration of bore accuracy. recommended whenever possible.
