Technical Guidance Drill FailureUnsatisfactory Hole AccuracyUnsatisfactoryChip Control Technical Guidance Tool Failure and Remedies Trouble Shooting Guide for Drilling Failure Basic Remedies Remedies Examples Excessive Wear on Cutting - Use higher cutting speeds. - Vc=80~100m/min Cutting Edge Conditions - Increase feed rates. - Refer to recommended cutting conditions listed in the general catalogue. Cutting Fluid - Reduce pressure if useing internal coolant. - Use cutting fluid with more lubricity. - Below 1,5MPa. Chisel Point Chipping Tool Design - Increase size of chisel width. - Increase amount of honing on cutting edge. Cutting - Reduce depth-of cut. Conditions - Reduce feed rate at entry point. - f = 0,05~0,1 mm/rev . Others - Improve workpiece clamping rigidity. Chipping on Tool Design - Increase amount of honing on cutting edge. Peripheral Cutting - Reduce the amount of front flank angle. Edge Cutting - Reduce cutting speeds.Conditions- Increase feed rates. - Refer to recommended cutting conditions listed inthe general catalogue. Cutting Fluid - Use cutting fluid with more lubricity. Others - Improve workpiece clamp rigidity. Margin Wear Tool Design - Increase amount of back taper. - Reduce margin width. Cutting - Reduce cutting speeds. - Refer to recommended cutting conditions listed in Conditions - Increase feed rates. the general catalogue. Cutting Fluid - Use cutting fluid with more lubricity. Others - Schedule for earlier regrind. Drill Breakage Tool Design - Increase amount of back taper. - Reduce margin width. Cutting - Reduce cutting speeds. - Refer to recommended cutting conditions listed in Conditions the general catalogue. Cutting Fluid - Use cutting fluid with more lubricity. Others - Improve workpiece clamp rigidity. Oversized Holes Tool Design - Improve overall dril rigidity. (large web, small flute). - Reduce drill point angle. - 130°~120° Cutting - Reduce feed rate at entry phase. - f = 0,05~0,1 mm/rev Conditions - Reduce cutting speeds. - Refer to recommended cutting conditions listed in the general catalogue. Cutting Fluid - Improve workpiece clamp rigidity. Others - Improve drill clamp precision. - Drill run-out below 0,02mm - Improve drill clamp rigidity. Poor Surface Finish Tool Design - Increase amount of back taper. Cutting - Increase cutting speeds. - Refer to recommended cutting conditions listed in Conditions the general catalogue. Cutting Fluid - Use cutting fluid with more lubricity. Holes are Not Straight Tool Design - Reduce amount of edge honing. Cutting Conditions - Reduce feedrates. - Refer to recommended cutting conditions listed in the general catalogue. Others - Improve workpiece clamp rigidity. - Improve drill clamp precision. - Drill run-out below 0,02mm - Improve drill clamp ridigity. Packing of Chips Cutting - Increase cutting speeds. - Refer to recommended cutting conditions listed in Conditions - Increase feed rates. the general catalogue. Cutting Fluid - Reduce pressure if using internal coolant. - Below 1,5MPa. Long Stringy Chips Tool Design - Reduce amount of edge honing. Cutting - Refer to recommended cutting conditions listed in Conditions - Increase feed rates. the general catalogue. Cutting Fluid - Reduce pressure if using internal coolant. - Below 1,5MPa. N16
