Fintek Showcases Cutting-Edge Developments in Post-Processing and Surface Finishing at MACH Exhibition

by Anna

Fintek, a leading presence at stand 19-16 in the ongoing MACH exhibition, is set to unveil groundbreaking advancements in post-processing and surface finishing techniques. Among their showcased innovations are enhancements tailored for larger components, superfinishing capabilities, and mass finishing solutions. As the UK agents for OTEC Präzisionsfinish disc, drag, and stream finishing machines, Fintek proudly presents the latest expansions in OTEC’s electro-finishing range.

In addition to machine sales, Fintek offers a comprehensive subcontract service catering to precision engineers across various sectors, including aerospace, motorsport, and medical device manufacturing. Recognizing the crucial requirements of speed, capacity, and precision in meeting in-line production demands, Fintek highlights the exceptional capabilities of OTEC stream finishing machines, which deliver repeatable surface roughness values as low as Ra 0.01µm. Notably, automation options such as increased chain-feed loading and unloading, alongside full robotised operation, further streamline manufacturing processes.

An outstanding feature of OTEC SF machines is the integration of ‘Pulsfinish’ technology, representing a pioneering approach to surface finishing. This innovative method generates rapid relative motion between the media and the metal workpiece by swiftly alternating the direction of rotating heads. The resulting fast acceleration and deceleration significantly enhance finishing forces, ensuring a flawless finish at an accelerated pace without compromising workpiece geometry.

Furthermore, all OTEC machines are equipped to meet the demands of Industry 4.0 standards. Fintek offers an advanced package for CF, DF, and SF machines, incorporating an industrial PC for enhanced digitalization. This facilitates superior machine monitoring and process optimization through remote maintenance, providing clear advantages to manufacturers.

In conjunction with OTEC machines, Fintek introduces the RENA Technologies Hirtization process to the UK market. This capability enables Fintek to offer advanced post-processing services for additive manufacturing (AM) parts as part of their subcontract service. Hirtization effectively removes support structures, powder cakes, and partially melted grains, even penetrating extreme geometry complexities and small diameter holes.

As Fintek celebrates its 42nd year at MACH 2024, the company reflects on its extensive experience in addressing the post-processing and surface finishing needs of UK component manufacturers. While they may not confirm the veracity of the answer to life, the universe, and everything—according to Douglas Adams’ iconic creation, Deep Thought—Fintek’s 42 years of dedicated service underscore their commitment to excellence. With ISO9001 and AS9100 accreditations, Fintek invites visitors to explore their offerings at MACH, stand 19-16.
