SOUDBniLL USER GUIDE Troubleshooting Problem Cause Solution Poor clamping of the chuck Check the clamping. Use hydraulic clamping chuck, maxin power chuck or a shrink system. Workpiece movement Increase workpiece chucking force. Wrong drill Check drill type and drilling depth, cooling system and workpiece material. Insufficient coolant Check cooling lubricant. Increase coolant pressure. In the case of external coolant supply, improve jet direction and add cooling jets. Unsuitable cutting conditions Reduce feed. Worn out drill center point (chisel) Regrind cutting edge. Drill breakage Chipping on the cutting corners Poor clamping of the chuck Workpiece movement Wrong drill Insufficient coolant Unsuitable cutting conditions Worn out or broken cutting corner Check the clamping and adaptation. Use hydraulic clamping chuck, maxin power chuck or a shrink system. Increase workpiece chucking force. Check drill type and drilling depth, cooling system and workpiece material. Possibly use longer drill. Check cooling lubricant. Increase coolant pressure. In the case of external coolant supply, improve jet direction and add cooling jets. Check cutting parameters, and possibly reduce feed. Replace drill or regrind cutting edge. Problem Cause Solution Burrs on exit Ra Unsuitable cutting conditions Worn out drill Reduce feed by 30-50% during exit. Replace drill. Unsuitable cutting conditions Adjust feed to improve chip flow. Rough surface finish Large runout Make sure that the drill's runout is within 0.02 mm (radial & axial). Chip jamming Reduce cutting speed. Increase coolant pressure. Apply pecking procedure. Large runout Make sure that the drill runout is within 0.02 mm (radial & axial). Poor stability Check and improve drill and workpiece clamping rigidity. Rough application When drilling hard materials or sloped surfaces, reduce feed by 30-50% during entrance. Deviation of hole position Use a short pilot drill with 140° point angle.
