Cleaning and Degreasing Before Deep Hole Drilling
Why Cleaning Matters in Deep Hole Drilling Cleaning and degreasing before deep hole drilling prevents contamination of the coolant system and the bore surface. A part that is dirty when it enters the machine can cause tool damage, surface finish defects, and coolant degradation. Deep hole drilling uses high-pressure coolant to flush chips from the bore. If the coolant carries dirt, sand, or scale from an uncleaned part, those contaminants recirculate through the system. In a typical BTA system with a 500-liter coolant tank and 40-bar pressure, the coolant circulates through the cutting zone hundreds of times per hour. Each pass carries contaminants across the cutting edges and guide pads. ...
