After a period of work, the surface of the grinding wheel of the spring grinder will be passivated, clogged and deformed, which will affect the surface quality of the workpiece to be processed. Therefore, the spring grinder must have a wheel dresser.
The designed grinding wheel dresser of the spring grinding machine has two operating handles, which respectively control the horizontal feed and the vertical feed. The horizontal feed is used for dressing the entire wheel, and the longitudinal dressing wheel is used to adjust the height of the dressing wheel and the height of the dressing wheel. The dressing method of the grinding wheel is to drive the metal-shaped grinding wheel to rotate at a low speed through the grinding wheel, thereby generating a squeezing force between the roller and the grinding wheel, thereby destroying the abrasive particles or bonding. The force is destroyed, thereby forming abrasive particles, in order to achieve the purpose of dressing the grinding wheel.
China's household spring grinder wheels still do not meet this quality standard. No matter what imported spring grinder wheels are famous, their quality is better than domestically produced spring grinder wheels. This is related to the life safety of the aircraft, so the quality of the grinding wheel of the grinding spring machine is the best, and the quality of the grinding wheel of the imported grinding spring machine is now the best. In particular, the quality of SKF spring grinder wheels is surprisingly good.
1. TrTun900 and GP7000 are launched
FAG is the sole supplier of a large number of spare parts for all jet grinder spring grinder wheels and the new Rolls-Royce "Trent 900". This launch provides power for the world's largest passenger aircraft. FAG will provide the second-generation Airbus A380 GP7000 jointly developed with Pratt & Whitney, Whitney and General Electric.
2. Rent up to 500 launches
FAG Aviation Grinding Spring Co., Ltd. and Rolls-Royce have worked closely together to develop a new spindle grinding spring for the Airbus A340-500 and A340-600Trent 500 in a very short period of time.
FAG success factors: 1. The FAG aviation grinding spring system is an important force to start the development of grinding springs. 2. Trent 500 engine provides extremely high power density. 3. The FAG test bench verified the reliability of the high-strength spindle spring.
3. PW4000 launch
More than half of commercial customers use Pratt and Whitney for publishing. More than 70 airlines are confident in the reliability of the PW 4000 release. The thrust is from 22 tons to 45 tons. Almost all large flights are manufactured by Airbus and Boeing.
FAG's success factors: (1) FAG Aviation Grinding Machine Spring Department is the supplier of all spindle spring grinding machines. In addition, FAG Aviation Grinding Springs Division is the authorized supplier of all gearbox grinding springs. Likewise, these abrasive springs must meet the highest standards of quality and reliability.
4. BR700 launch
BR700 introduced an integrated spindle grinding spring configuration: FAG Aviation Grinding Springs developed a spindle grinding spring configuration for the BR700. These launches were developed by Rolls-Royce of Germany and used for Boeing, Bombardier and Gulfstream regional and commercial jet flights.
FAG's success factors: 1. "Synchronous engineering technology"-product development and users "go hand in hand" 2. Through system integration, product weight and number of parts are reduced, and costs are saved. The grinding spring and integrated spindle assembly are welded by electron beam.
