Fintek to exhibit post processing and surface finishing expertise at MACH

1 min read

Fintek is on stand 19-16 at MACH. They will show developments in post-processing and surface finishing, including larger components, superfinishing and mass finishing. Fintek are UK agents for OTEC Präzisionsfinish disc, drag and stream finishing machines. For this year, OTEC has expanded their electro-finishing range.

Besides machine sales, Fintek provide a full subcontract service to precision engineers. Processing components for manufacturers in aerospace, motorsport, medical device and more.

Manufacturers need speed, capacity and precision to meet in-line production needs. With repeatable surface roughness values down to Ra 0.01µm possible, OTEC stream finishing machines meet these objectives. Automation options include increased chain-feed loading and unloading along with full robotised operation.

OTEC SF machines can be equipped with ‘Pulsfinish’. This pioneering technology produces rapid relative motion between the media and metal workpiece. It achieves this by quickly alternating the direction of the rotating heads. Fast acceleration and deceleration amplify the finishing forces exerted on the workpiece. This produces a perfect finish, faster and without compromising workpiece geometry.

All OTEC machines are Industry 4.0 ready. An advanced package is also available on CF, DF, and SF machines. This includes an industrial PC to give more advanced digitalisation. Superior machine monitoring and process optimisation via remote maintenance are clear benefits.

Alongside OTEC machines, the company brings to the UK the RENA Technologies Hirtisation process. This allows Fintek to offer AM part post-processing as a subcontract service. Hirtisation removes support structures, powder cakes and partially melted grains. It penetrates extreme geometry complexity and small diameter holes.

MACH 2024 sees Fintek reach its 42nd year. Forty-two is the answer to the ultimate question of life, the universe and everything! At least, according to Douglas Adam’s creation, Deep Thought, a giant computer in his acclaimed book, Hitchhiker’s Guide to the Galaxy. Fintek may not be able to verify that answer. Yet, 42 years serving the post processing and surface finishing needs of UK component manufacturers is no small feat. They bring this wealth of cross-industry expertise to their customers.

Fintek are ISO9001 and AS9100 accredited. See them at MACH, stand 19-16.
