Technical Guidance Technical Guidance Tool Failure and Remedies Trouble Shooting Guide for Drilling Failure Basic Remedies Remedies Examples Drill Failure Excessive Wear on Cutting Edge Cutting Conditions Cutting Fluid - Use higher cutting speeds. - Increase feed rates. - Reduce pressure if useing internal coolant. - Use cutting fluid with more lubricity. - Vc=80 100m/min - Refer to recommended cutting conditions listed in the general catalogue. - Below 1,5MPa. Chisel Point Chipping Tool Design Cutting Conditions Others - Increase size of chisel width. - Increase amount of honing on cutting edge. - Reduce depth-of cut. - Reduce feed rate at entry point. - Improve workpiece clamping rigidity. - f = 0,05 0,1 mm/rev . Chipping on Peripheral Cutting Edge Tool Design Cutting Conditions Cutting Fluid Others - Increase amount of honing on cutting edge. - Reduce the amount of front flank angle. - Reduce cutting speeds. - Increase feed rates. - Use cutting fluid with more lubricity. - Improve workpiece clamp rigidity. - Refer to recommended cutting conditions listed in the general catalogue. Margin Wear Tool Design Cutting Conditions Cutting Fluid Others - Increase amount of back taper. - Reduce margin width. - Reduce cutting speeds. - Increase feed rates. - Use cutting fluid with more lubricity. - Schedule for earlier regrind. - Refer to recommended cutting conditions listed in the general catalogue. Drill Breakage Tool Design Cutting Conditions Cutting Fluid Others - Increase amount of back taper. - Reduce margin width. - Reduce cutting speeds. - Use cutting fluid with more lubricity. - Improve workpiece clamp rigidity. - Refer to recommended cutting conditions listed in the general catalogue. Unsatisfactory Hole Accuracy Oversized Holes Tool Design Cutting Conditions Cutting Fluid Others - Improve overall dril rigidity. (large web, small flute). - Reduce drill point angle. - Reduce feed rate at entry phase. - Reduce cutting speeds. - Improve workpiece clamp rigidity. - Improve drill clamp precision. - Improve drill clamp rigidity. - 130° 120° - f = 0,05 0,1 mm/rev - Refer to recommended cutting conditions listed in the general catalogue. - Drill run-out below 0,02mm Poor Surface Finish Tool Design Cutting Conditions Cutting Fluid - Increase amount of back taper. - Increase cutting speeds. - Use cutting fluid with more lubricity. - Refer to recommended cutting conditions listed in the general catalogue.
