A complete guide to chip formation and evacuation in deep hole drilling. Chip shapes, breaking mechanisms, coolant parameters, troubleshooting, and material-specific strategies for reliable chip control.
Why coolant is more critical in deep hole drilling than conventional machining. The three functions — cooling, lubrication, chip transport — and why low-pressure systems fail at depth.
How to calculate coolant pressure and flow rate for deep hole drilling. Formulas for gun drilling and BTA systems, pump sizing guidelines, filtration requirements, and diameter-based reference charts.
A technical comparison of deep hole drilling and conventional twist drilling across 10 dimensions: tool design, chip evacuation, coolant delivery, precision, surface finish, straightness, productivity, cost, and decision thresholds with data.
Comprehensive troubleshooting for deep hole drilling. Chip clogging, drill breakage, guide pad wear, bore diameter variation, coolant issues, and chip formation problems. Causes and proven solutions.
