Deep Hole Drilling Systems

ProblemPossible CauseSolution
The drill breaks or insert chips• Chip evacuation problems • Center misalignment of drill to workpiece• Check that the coolant passages are clear and that the Venturi slots are not damaged • Check center alignment of drill to workpiece • Check workpiece and drill clamping rigidity
Poor surface finish• Workpiece or drill clamping rigidity problem • Inadequate coolant oil • Cutting speed too low• Improve workpiece or drill clamping • Check the coolant oil and replace if necessary • Increase the cutting speed
Excessive leakage of the coolant• Chips block the fluid passages • The drill was incorrectly assembled, or the Venturi slots of the internal tube are located in the wrong direction• Clear the chips • Check all connections and the direction of the internal tube
Insufficient coolant flow at the cutting zone, despite correct fluid supply• Chips block the fluid passages • Worn bushing or sealing device • Venturi slots are too wide (worn) • Internal tube shorter than the external tube• Clear the chips • Check the bushing and seal and replace if necessary • Replace the internal tube • Replace the internal tube to one with a correct length
Chips jam in the front end of the drill• Insufficient coolant flow• Adjust the fluid flow by raising the pressure; check the filter and fluid quality
