Xiamen Golden Heron: Successfully developed aviation pneumatic tools

According to reports, the tool research and development personnel of Xiamen Jinlu Special Alloy Co., Ltd. have successfully developed aviation pneumatic tools for the processing of composite structural parts. The main products include drill bits, reaming drills, reamers, boring drills and drill-bending composite knives. 5 series. The drill bit, the reaming drill and the reamer are divided into a straight shank and a threaded shank, and the boring drill is divided into a taper shank and a threaded shank.

It is reported that in this series of products developed by Xiamen Golden Heron, the drill bit adopts a special drill-type structure, the drilling force is small, the impact force of the workpiece is small, the drilling process is stable, and the drill bit can be easily cut during the drilling process. Composite fiber, burr, delamination and other defects in the entrance and exit of the hole. Reaming drill, reamer and boring drill can be equipped with positioning guide column, which can be positioned accurately in the secondary machining hole, which can ensure the coaxiality of the two machining holes before and after, and reduce the defects such as burrs and flanging at the entrance and exit of the drill hole. . The small size of the threaded shank tool is especially suitable for use in environments where machining space is limited. The Drilling Reaming Knife uses a special knife-shaped structure design and Jinlu's “green frost” diamond coating. When processing composite materials or composite laminates, it can complete the drilling, expansion and reaming at one time, reducing the processing steps. The production efficiency is improved, and the positioning error caused by the tool change is reduced, and the surface quality of the workpiece is ensured.

At present, the aviation air tools developed by Jinlu Company have been put into production in batches, and are widely used in the connection and assembly of titanium alloy, aluminum alloy and composite superimposed plates in the Chinese aerospace field.
