What We Do:

Achieving high quality metal part surface finishes is no longer a luxury – it is a vital necessity in all branches of advanced engineering. Tolerances are increasingly precise and hard, if not impossible, to achieve by hand consistently. Customer expectations for more reliable end-products relentlessly drives development.

For over 30 years Fintek has been at the forefront of surface finishing. As UK agent for OTEC Präzisionsfinish GmbH, we have access to an unrivalled range of disc, drag, stream and pulse finishing machines capable of producing surface Ra values to 0.01 μm in a fraction of the time taken by costly hand finishing and other traditional processes.

From single units to fully automated mass finishing systems for inline production, we can supply everything you need to ensure repeatable and cost effective surface finishing of your metal components that meets or surpasses your required quality standards.

We also provide a full range of deburring, fine grinding, edge radiusing, smoothing, polishing and superfinishing subcontract services using the latest generation of OTEC equipment. A same-day service is available.

Whether you want a machine or to outsource your metal part finishing to us, we are happy to process a trial part, free of charge.


"They are technically superb, with the sub-contracting service being second to none."
Tony Flower - Ricardo

"Our interest in Fintek was first prompted at the MACH show where we were presented with a demonstration of the rotating parts. We decided to try them with some samples and to our amazement they came back with a finish that was so good they were good enough to wear as a piece of jewellery never mind to use in an engineering application!"
Jason Ward - AE Aerospace
