Fintek has added to its existing AS9100 and AS9001 accreditation by gaining GE certification for mass surface finishing.

The new certificate is an important milestone for the company as it continues to expand its subcontract surface finishing services in the aerospace sector.

Fintek is engaged with several aerospace component manufacturers, working closely with them to eliminate production bottlenecks where hand and traditional finishing methods are not able to achieve higher quality surface finishing requirements in shorter times.

Of particular concern for many aerospace parts manufacturers is unseen damage caused by manual deburring using small powered hand tools. These can sometimes cause accidental nicks that can compromise fatigue requirements, possibly with catastrophic consequences. Another hand finishing issue is missed burrs that are subsequently peened over. Again these can become sources of component failure.

OTEC stream finishing machines have been used to create bespoke surface finishing processes for aerospace component manufacturers

Key in addressing these issues has been the introduction of highly controllable stream finishing systems by OTEC Präzisionsfinish. Fintek, who represent OTEC in the UK, has been able to develop special processes to dramatically improve the efficiency and, importantly, the quality of the surface finishing for aerospace manufacturers. Typical components benefiting from superior and more consistent surface finishing includes turbine blades, extremely thin parts, gear wheels, fasteners and even cutting tools.

To accommodate additional stream finishing units and meet demand for these processes, Fintek is planning to extend its existing facility.

Jonathan Dean, managing director, said: “These are exciting times as much of the research and development work we have undertaken with F1 teams, the pinnacle of motorsport, is proving to be adaptable to aerospace and we can offer manufacturers mass finishing options to boost productivity and quality where previously they did not exist. This GE certification is another step forward for us.”
