Manual air drill drilling damages the quality of aerospace composite hole machining

In the aerospace industry, the use of manual air drills for drilling accounts for approximately one-third of the application of composite hole machining, and the continuous improvement of this application area has brought a very good return. While striving for better machining results, performance and economy, cutting tools play an increasingly important role in the application of such cutting versatility. Non-standard drills have evolved over time, and recent innovations have opened the door to the possibility of using standard tool sets. The continuous development of non-standard drills and recent technological innovations have made the introduction of new standard tooling solutions possible.

In aircraft parts and structural parts, the application of drilling composites and laminates is mainly the processing of a large number of bolt holes and rivet holes. Manual manual operation by the operator means that these processes face certain challenges. Processing with manual air drills tends to be unstable and process stability is difficult to guarantee. The performance of the equipment and tools used and the operator's work experience will directly affect the hole quality and production efficiency.

If ordinary manual tools are used for hole machining, it is easy to be affected by the bit grabbing effect. At the same time, a large thrust is required to penetrate the workpiece, so that the quality, efficiency and operator fatigue of the processed holes will be negatively affected. If such problems are not solved, the hole outlet may have unacceptable burrs, delamination at the end of the hole, and defects such as fibers that are difficult to cut. Ordinary drill cutting composite materials, the cutting effect is poor, the feed changes greatly, which requires the operator to balance the adverse effects brought by the ordinary drill bit through proper operation, and the result is more likely to produce waste.
