🔊Counting on STUDER for Evermore

Evermore has been manufacturing machine components in China for over two decades, for the automotive and medical technology sectors. Thanks to machines from STUDER, it has significantly increased manufacturing efficiency and quality.

Wearing his work jacket, operations specialist Chen stands in a machine hall in the north of the Chinese metropolis Jiaxing and watches the control panel of an S31 cylindrical grinding machine. Along with many other machines, it hums industriously in the meticulously organised hall. “The STUDER machine works reliably and has a very high machining accuracy; the waste rate is low”, says Chen. The expert has been working for the manufacturer for 18 years and is currently monitoring the production of Evermore’s C6 type tool holders.
A few metres away are polished workpieces, reminiscent of a museum with conical shapes made of high-alloy steel, tool holders, and chucks for tools such as drills. “Our customers appreciate the uncompromising quality, both in terms of geometry and surface finish,” says Barry Liao, the General Manager of Evermore. Whether precision components for the automotive industry, computer electronics, hydraulics, medical technology, or other areas of metal processing, the company has built an excellent reputation.

Success Through Trust
This successful journey began in 2000 when Liao’s father founded the subsidiary in Jiaxing. Initially focused on manufacturing precision machine accessories such as CNC chucks, tool systems, and tool holders, Evermore steadily expanded its portfolio and invested in advanced manufacturing technologies and optimised production and management processes. During this time, China has developed into a world-leading technology and industrial nation, and Evermore has been able to hold its own in this demanding competitive environment thanks to its high standards. “Our success is also inseparably linked to the close cooperation with STUDER,” says Liao.
Standing next to him in the showroom is Wu Kui, Sales Manager & Senior Sales Technology Support from UNITED GRINDING China, who looks after STUDER customers in the country. “With the extensive expertise of our specialists, we were able to competently advise Evermore from the beginning on which machines and configurations are best suited for their production processes. I personally trained some employees on STUDER machines,” Wu recalls. Thanks to this guidance, it was possible to implement multiple grinding functions, the grinding of precise internal and external contours or non-round geometries and end faces in a single machine, which has significantly increased production efficiency.

Several STUDERs in Operation
Several STUDER machines are in use at the14,000sq/m site with 230 employees. Two S131 CNC universal internal grinding machines have a permanent place. One makes high-precision internal bores in polygon shaft components, while the other grinds internal threads for miniature adjustment screws. The S131 features the innovative StuderGuide® guideway system, high-precision axis drives with linear motors, fast direct drive of the grinding spindle turret, or the automatic swiveling function of the workpiece table.
Meanwhile, the S31 cylindrical grinding machine is responsible for grinding precise external diameters of polygon shaft components. This is ideal for small to medium-sized workpieces with a maximum weight of up to 150kg. The swivelling wheelhead with a high-resolution B-axis of 0.00005° allows external, internal, and face grinding in a single setup. And the stable machine bed made of solid Granitan® S103 reduces vibration and thermal influences for repeatable surface quality. Finally, a KC33 reliably produces the external threads of the adjustment screws.

More Efficient Production
“We chose STUDER because they enable precise machining with dependable process reliability,” explains Evermore’s General Manager. This, along with the reduction in processing times through fast setup and retooling, simple operation, and automation options, has significantly reduced production costs.
“For us, it is important to support our customers as quickly and competently as possible. Anyone who purchases a STUDER machine also receives excellent customer care,” says Wu. The General Manager nods in agreement and recalls a situation some time ago when a machine had to be urgently set up for a new customer order: “The STUDER team gave extremely professional advice that significantly optimised our production process.”
Liao expects this collaboration to become even more important in the future. Many of his customers in industries such as automotive, electronics, or medical sectors require increasingly precise components, often made from demanding materials, to meet the steadily increasing requirements for efficiency and accuracy. It is a great advantage that STUDER, as a Swiss quality manufacturer is among the global innovation leaders in grinding technology and continuously works on new features that ensure the continued success of its customers.
