Reducing Cycle Time in Deep Hole Drilling: Practical Tips
Cycle time reduction in deep hole drilling is a balancing act between speed and reliability. I have reduced cycle times by 30-40% on some jobs without degrading hole quality, but pushing too hard causes tool breakage and scrap. The key is knowing which parameters to change and in what order. Problem Description Deep hole drilling is inherently slow compared to conventional drilling. The depth-to-diameter ratio limits the feed rate, the peck cycle adds retract time, and the need for chip evacuation constrains the speed. The challenge is reducing the time per hole without causing chip blockages, tool breakage, or surface finish defects. ...
