Fintek Bring in a Step Change in Aerospace Component Surface Finishing

To meet rising demand for ever more precise surface finishing of aerospace components, Fintek have invested in a latest generation stream finishing machine from OTEC Präzisionsfinish GmbH. The new advanced capabilities of the machine will also make it a perfect platform for further research and development projects with aerospace customers.

“The new SF is important for our aerospace work to ensure the precise profile tolerances now needed for turbine blades are met. For example, the control provided by the new step motor technology lets us frequently vary and lock the angle of the blades as they pass through the process media to carefully manage the finishing effect on vital leading and trailing edges,” explained operations manager Jamie Phillips.

With AS9100 and ISO9001 accreditation, six other stream finishing machines, along with drag finishing and centrifugal finishing systems, Fintek has the capacity, depth of knowledge and expertise to provide a full range of surface finishing services. These include deburring and mirror-finish polishing to smoothing and polishing, as well as important edge rounding. For aerospace, this covers not just turbine blades but also complete blisks, gear wheels, cutting tools, fasteners and extremely thin parts.

“Problem solving is integral to our service. We work closely with aerospace customer engineers, including in research and development, to create better parts by applying surface finishing techniques that meet their commercial objectives. Often we are able to achieve a quality of surface finish in minutes (sometimes seconds) that can’t be matched by hand or other traditional methods. Furthermore, processes are precisely repeatable to ensure total quality consistency and confidence to achieve surfaces with values of up to Ra 0.01,” added Jamie.

Fintek is well known for our work with top level teams in motorsport, where degrees of perfection translate into reliability and 1000’s of a second on track. This rapid technological test bed enables us to constantly expand our surface finishing knowledge base and apply this to other precision industries such as aerospace, medical devices and more.

For aerospace companies requiring on-site processing, Fintek are exclusive UK agents for OTEC and we can supply and install machines backed with extensive expertise.
