A MACHINIST AND A COMPUTER WIZARD
Half of Mr. Jari Piili’s daily working time is spent at the computer – programming and designing 3D models. So is he a software developer?No, he’s a machinist specially trained for his job by his employer, ATA Gears, designer and manufacturer of world-famous bevel gears. A machinist’s job is not dirty work requiring brute force. No
FREE YOUR MIND WITH 5-AXIS: OFFERING A STRONG COMPETITIVE EDGE
All kinds of cylindrical gears can be manufactured using 5-axis technology. A good example are herringbone gears used in applications where the rotating speed of the gear is really high, for example in the reduction gear of a gas turbine. To achieve a smaller housing with cheaper and simpler bearing arrangements, using the 5-axis technology
CUTTING-EDGE RESEARCH BY KONGSBERG AND ATA GEARS MAKES NEW DISCOVERIES ABOUT TFF
André Böhme has a mission: fighting TFF. Subsurface fatique, TIFF or TFF, is causing several unforeseen gear failures and thruster replacements every year. It is the predominant failure mode on bevel gears used in azimuth thrusters onboard state-of-the-art vessels. And fatigue or overload can destroy any gear. For good reason, there is very innovative, comprehensive

HOW TO GET IT RIGHT THE FIRST TIME – AND EVERY TIME
With gears over 3 metres in diameter Big gears almost always run vital processes, which are often also a company’s most expensive ones. In many cases the company may have no backup equipment and any breakage can easily cause long downtime, possibly even resulting in the company being unable to finish the job or continue
BEVEL GEAR QUALITY IS NOT GUESSWORK
The best raw materials, state-of-the-art design, engineering tools and know-how, in-house heat treatment, fine-machining and super-finishing: That’s what’s behind all ATA Gears’ solutions and deliveries. But even that is not all. You could almost say that it takes just about as many quality factors to make a bevel gear as that gear has teeth. A
CASE HARDENING – THE HEAT IS ON
Gears are expected to function reliably for years or even decades under extreme loads, so case hardening is one of the key development areas in this specific field of mechanical power transmission. That’s why ATA’s Gear Doctors are ceaselessly researching heat treatment and material science. Water jet cutting, sample cutting, grinding and polishing, adding to
