Quality & accurary in the manufacture of high-precision parts:
Aerospace specialist IFT opts for an OTEC finish
The exacting safety, precision and quality standards of the aerospace industry are as stringent as it gets. Every single manufacturing step has to be closely monitored and documented. Not every production facility can meet these multi-level requirements. OTEC customer IFT GmbH & Co. KG, based some 30 miles south of Frankfurt in Ober-Ramstadt, specialises in high-precision parts for the motorsport, medical technology and aerospace industries.

Precise, effektive Surface processing: The Special requirements of lasercut parts
Laser cut parts are used in many industries, from jewellery to automotive, electrical and optical engi-neering. Once manufactured, their edges are slightly burred, and the parts often suffer from unsight-ly discolouration. Much of the time, these defects are removed by hand, which is time-consuming and costly. The challenge is almost always the same: how to deburr and polish extremely thin parts – i.e. less than 0.4 mm thick and usually made of stainless steel – without changing their geometry. But also, during processing, how to prevent the parts from chafing against each other, or from get-ting wedged in the container or stuck in the gap.
"Growth through innovation": from Startup to mediumsized Technology leader
The company was founded in 1996 by Helmut Gegenheimer and Soran Jota in Straubenhardt, near Pforzheim in the Southern German state of Baden-Württemberg. Since then, as a specialist in surface processing, it has grown from a mechanical engineering startup serving the jewellery and watchmaking industry to a global technology leader in deburring, grinding, smoothing and polishing. Today, international customers from industries as diverse as jewellery and watchmaking, medical devices, pharmaceuticals, automotive and aerospace, electronics, toolmaking and additive manufacturing rely on the expertise we’ve acquired over the course of more than twenty years. Here's an insight into the OTEC Story, with CEO Helmut Gegenheimer.

DENTAL DRILLS: OTEC PRODUCES OUTSTANDING RESULTS IN 60 SECONDS
The manufacturing process for stainless steel surgical drills used in minor or major procedures produces burrs. Manual deburring is not just time-consuming but also produces a lot of rejects, not to mention the fact that every drill ends up slightly different. It’s an unreliable process. OTEC SF Series machines are designed for reliable, reproducible precision processing. Drills pose specific challenges.

The DF machine from OTEC ensures the correct combination of abrasive, tool holder and process parameters for a surface finish that is on a par with hand-finished quality. To guarantee these results, OTEC supports its customers by using its long years of expertise to develop customised processes.
02/2019: Parts for glasses
A unique zero gap system for damage-free processing
Glasses are mainly worn as an optical aid to correct defective vision and misalignment, in which case they are also referred to as corrective glasses. The parts for glasses have to be deburred, rounded and highly polished. Due to OTEC's unique zero gap system, small metallic parts for glasses can processed without damaging and get a flawless, highly polished surface.
