Zet Reducer attracts the attention of the world with its special gears: Zet Gearbox, one of the most important names of the sector with its gear sets produced for trains, became one of the three suppliers in the world of gear and gearbox. We had a talk with Ahmet Özyazıcı, Zet Reducer Factory Manager, about the special gears produced by their companies and their projects for the sector.
Zeta Gear, Turkey's first reducer as well as being one of the special gear and gearbox production company also achieved the success of the Spanish company CAF will be one of the suppliers are talked about in the railway. The company can produce gear up to a thousand millimeters and believes that if it is assigned in the national train project, it will make a successful result. Ahmet Özyazıcı, Zet Reducer Plant Manager, is among the members of the Rail Systems Cluster. Tarih I personally participated in the de National Train Project Consultation and Cooperation Meeting İst held in Eskişehir under the leadership of TÜLOMSAŞ on 25.11.2014. It was remarkable that people were excited. After this meeting, alar Sector Research Survey Bu was completed by participating companies. I think that TCDD evaluates the capacity of companies and their capabilities in rail systems. We have gear and gear box in rail systems. In this direction, we are ready to do our part in this matter when a demand related to the National Train Project is received.
Can you get information about Zet Redüktör's product range, production capacity and the technological equipment you use in production?
The introduction of ZET Gearbox to the rail systems sector started with 2011 at the Hannover Messe fair, where the Spanish CAF, which also made high-speed trains in our country, visited our booth. At the end of the negotiations, the company started to visit us after the gear and gear box manufacturing demanded from us. Since then, we have become one of the three suppliers of CAF in the world. Of course, these products really want information, knowledge and technology. If you do not have a good technological infrastructure, it is very difficult to run in this lane. As a gear design program, we have the KISSSOFT program of Swiss origin. In addition, all gear and gear boxes are manufactured in CNC machine tools. Our CNC gear profile grinding capabilities up to 1.000 mm are more than enough for this sector. In addition, the ability to measure the gears we produce is the most important factor in choosing the CAF.
You produce gear sets for trains. Technical characteristics of your gears, what are the projects used?
The gear sets we produce for trains are really special. In addition to threaded profiles, manufacturing and testing methods require a number of special processes. Once gear profiles are very different from other gears. Here in the literature protubeThe profile called rance is preferred. A separate gear knife is designed and supplied for each gear. Gear manufacturing is done with these. The tooth bottoms are absolutely not ground. Consequently, the life of the gears is much longer by minimizing the risk of deformation and breakage at the tooth bottoms. Of course, when you go down to the theory of business, these topics will take pages. There are many technical details, but these gears are really special.
Rail systems, especially high-speed trains; sectors that will not remove the error. In this context, what do you pay attention to your gear production? As a company that provides services to this sector, what are you focusing on R & D studies?
If human life is entering the business, there is no room for error in this work. Once you supply the gear material, the heat treatment you make, your production methods and their control, they have to be extremely precise and precise. We use material with the standard 18CrNiMo7-6 as gear material. During the production of these gears, we apply 3 type heat treatment as isothermal annealing, cementation and subzero. MPI (Magnetic Particle Test) crack control and Nital tests are performed at the last check of the gears. As far as I know in Turkey for us is no need for any other gear manufacturers are making nital test. Gear materials as they enter the production of eggs in special containers in the process of manufacturing continues. Because, during and after manufacturing, a track gear, which can be as large as the head of a pin, causes scrap to be scraped. In the end, you deliver your gear and gear boxes to a customer with a folder report.
Eskişehir Railway Systems Cluster as a member rail projects in Turkey, how do you evaluate the role of local companies in these projects?
In accordance with a decision taken on October 11 2012 National Railway Project was initiated in Turkey. Within the scope of this project; High Speed Train, New Generation Diesel Train Set (DMU), New Generation Electric Train Set (EMU) and New Generation Cargo Cars are intended to be produced with minimum 51 locality ratio. Within the scope of this project, cooperation has been realized with institutions such as ITU, TUBITAK and ASELSAN.
The experiences of the companies established in the first years of our Republic as TÜLOMSAŞ, TÜVASAŞ and TÜDEMSAŞ, are the advantages of these companies. However, the fact that they could not keep up with the technologic era is a disadvantage. However, I think that this disadvantage can be turned into advantage with domestic private companies that have caught up with technology. Besides, I think that will play a role in terms of private sector in Turkey will have them next to the main sectors of the industry in the number of firms potentially serious sex will be ignored.
How do you evaluate the national high-speed train project, do you have a task in the project?
I personally participated in the “National Train Project Consultation and Cooperation Meeting are held in Eskişehir under the leadership of TÜLOMSAŞ on 25.11.2014. It was remarkable that people were excited. After this meeting, alar Sector Research Survey Bu was completed by participating companies. I think that TCDD evaluates the capacity of companies and their capabilities in rail systems. We have gear and gear box in rail systems. In this direction, we are ready to do our part in this matter when a demand related to the National Train Project is received.
What's on your agenda now? Could you inform us about the projects and new investments that you are preparing to implement in 2015?
Unfortunately, there is nothing in our agenda regarding rail systems. However, we are working with the Spanish CAF company. Last year, we launched the project that they described as the Astra project. At the beginning of this year we started the Valencia project. Millet National Railway Project in Turkey say.
