The S31 has been acquired by the Wuhan Hangda Aero Science & Technology Development Company in China.
The company develops high-precision components for the aviation industry at its Dongxihu site in China. Due to the company experiencing steady growth it decided to invest in a new precision cylindrical grinding machine. After careful consideration and detailed technical discussions, Studer was awarded the contract for the S31.
The S31 is an all-round capability grinder, suitable for medium-sized workpieces 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, is used in the machines.
In 2000, the first S31 cylindrical grinding machine left Studer’s factory at Steffisburg in Switzerland. That first machine installed at Shvabe Munich GmbH in Geretsried, Germany, is still in operation today.
“We are still very satisfied with our S31,” comments Tobias Traut, head of the grinding department 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 facility, we appreciate the high accuracy and that the machines are universally applicable.”
Yongjun Wang, deputy general manager at Wuhan Hangda Aero Science & Technology Development at the handover of the new machine said: "A Studer cylindrical grinding machine is the guarantee of the highest quality. We already have several Studer machines in our factory. And this is a selling point that also gives our customers confidence in our quality.”
An additional benefit for the company, aside from being able to grind high-precision aircraft components, are the many features such as external and internal cylindrical grinding, thread grinding and high-speed form grinding, which the S31 machine offers Wuhan Hangda.
