Wuhan Hangda Aero Science & Technology Development Co., Ltd. develops high-precision compo-nents for the aviation industry at the Dongxihu site in China. The company is experiencing steady growth and decided to invest in a new precision cylindrical grinding machine. After careful considera-tion and detailed technical discussions, Fritz Studer AG was awarded the contract for the S31. A spe-cial event: Towards the end of 2018, STUDER delivered the 1 000th S31 to Wuhan Hangda.

The S31 is an all-rounder - suitable for medium-sized work-pieces in single, small and large series production. It scores in its compact size and is especially popular with contract manufacturers who have very high and often complex requirements for cylindrical grinding. 2'500 tons of Granitan® , a mineral casting that provides a vibration-damping, thermostable and wear-free machine bed, are used in 1'000 machines. An impressive figure in a successful history.

At the turn of the millennium, the first cylindrical grinding machine S31 left the halls of STUDER in Steffisburg, Switzerland, and it is still in operation today. It is installed at Shvabe Munich GmbH in Geretsried, Germany. "We are still very satisfied with our S31," says the head of the grinding depart-ment at Shvabe. The machine is in full operation for external and internal cylindrical grinding. The additional functions for form and thread grinding are used for the production of prototypes. "On the S31, as on all STUDER machines that are used in our house, I appreciate the high accuracy and that the machines are universally applicable," continues Tobias Traut. He proves that the S31 is an ex-tremely reliable and consistent machine.

Yongjun Wang, Deputy General Manager at Wuhan Hangda Aero Science & Technology Develop-ment Co., Ltd., can be pleased. With the S31 he receives a machine with the highest precision, which will pay off for Wuhan Hangda. "A STUDER cylindrical grinding machine is the guarantee for the high-est quality," Yongjun Wang is convinced. A great benefit for him, apart from the advantage to grind high-precision aircraft components, are the many features such as external and internal cylindrical grinding, thread grinding and high-speed form grinding. Thus, Wuhan Hangda can realize various grinding applications on just one machine. "We already have several STUDER machines in our factory. This is also a selling point for our customers and with this we also gain their confidence, "says Yongjun Wang from his experience. With obvious pleasure he takes ownership of the 1'000th S31 in a festive setting.
