Deburring Bores in Composite Aircraft Parts

Posted on: March 7, 2018
Tags: COFA, Aerospace, Deburring, Composite

There are two major challenges to machining composites: one is to cut the fibers neatly without fraying; the other is that the abrasiveness of the material leads to heavy wear on the cutting edge of the tool blade. HEULE worked with this aircraft manufacturer to develop a cost-effective solution (a tool with a long blade life) that would also deburr the bore neatly.

A subcontracting company to the automotive and the fittings industry produces a range of components such as flanges, sprockets and drive shafts and was looking for a solution to reduce cycle time for drilling, deburring, and chamfering a sprocket wheel. 

Previously, the customer used a full carbide drill for the hole and a front and back deburring tool for removal of the burrs. The cycle time for all 12 bores amounted to 320 seconds. Since the deburring tool failed to produce a consistent chamfer, the sprockets had to be reworked manually outside of the machine.

A subcontractor to the automotive industry used to deburr a fork laboriously by hand. The fork is part of the steering column. Faced with the problem that the manual deburring was too time-consuming and that it became a bottle neck in the production process, the company set out to look for a new solution.

An artificial joint manufacturer in the medical technology field was not happy with the existing manual deburring solution of a crossbore in a knee replacement part and the quality of the parts being produced. As demand for the product increased and the manufacturer was faced with an increasing number of bores to be deburred, the quality of the product began to decrease.

Back Spotfacing in Inconel 718 on an Aircraft Component

An aerospace manufacturer was machining 30 back spot facings in a component made of Inconel 718 for some years. To do this, the part needed to be set up several times because of the poor accessability of the bores. Countersinks were carried out by a box column drill. For the other counterbores, he used a counterbore tool with a plug-in head for the back bore machining. The process time amounted to approx. 6 hours for one component. His goal was to simply speed up this process. Due to the very demanding material and the difficulty of accessing the machining spots, the customer was very skeptical with regard to new solutions.
