Studer Sells 1,000th S31

Franz Studer AG recently sold its 1,000^th S31 cylindrical grinding machine to Wuhan Hangda Aero Science & Technology Development Co., Ltd., in China. Wuhan Hangda develops high-precision components for the aviation industry at the Dongxihu site in China.

The S31 is designed for medium-sized workpieces in single, small and large series production. It features a compact size and tends to be popular with contract manufacturers who have high and often complex requirements for cylindrical grinding.

Yongiun Wang, deputy general manager at Wuhan Hangda, says that the machine delivers many features such as external and internal cylindrical grinding, thread grinding and high-speed form grinding. “We already have several Studer machines in our factory, which is a selling point for our customers,” he says.

At the turn of the millennium, the first S31 was shipped from Steffisburg, Switzerland, and it is still in operation today at Shyabe Munich GmbH in Geretsried, Germany. 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," says Tobias Traut, head of the grinding department at Shyabe.

Studer grinding machines are distributed in the U.S. by United Grinding North America Inc.
