Bury-based surface-finishing company Fintek, which is celebrating its 42nd anniversary this year, will show developments in post-processing and surface finishing, including larger components, superfinishing and mass finishing at MACH 2024, which is taking place 15-19 April at the NEC, Birmingham (Hall 19, Stand 16). 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 sub-contract service to precision engineers and is ISO9001 and AS9100 accredited. 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 additive manufacturing part post-processing as a sub-contract service. Hirtisation removes support structures, powder cakes and partially melted grains. It penetrates extreme geometry complexity and small diameter holes.
