Drilling depth control is essential to ensure accuracy and avoid issues such as material waste or poor-quality work. Common methods include using a depth scale or stopper for consistent settings, measuring actual hole depth with calipers or gauges for precision, and employing drill bits with shoulders that limit penetration. On CNC drilling machines, depth is precisely controlled through programming, offering high repeatability and accuracy.
Controlling the drilling diameter is equally important for ensuring fit, dimensional accuracy, and performance of the finished part. This involves choosing the right drill bit for the material, pre-drilling center holes to guide larger bits, and adjusting speed and feed rates to prevent overheating or oversizing. The use of cutting fluid improves accuracy by cooling and lubricating, while regular maintenance and sharpening of the drill preserve precision.
During drilling, attention to operational precautions is vital. The drill must remain stable to avoid deviation, which can be managed using fixtures or guide rails. Chip removal is necessary to maintain drill performance, especially in deep holes, where intermittent drilling helps clear debris. Lastly, safe operation must be always followed, including wearing proper personal protective equipment (PPE) like safety glasses, gloves, and masks.
