Starrag paves the way for Wilson to start a new era of precision machining

Jiangyin Wilson Precision Equipment Co., Ltd. (Wilson) is a high-tech company specializing in the machining of medium-sized and large precision components. Wilson is an important supplier of the wind power, compressors, machine tools, and textile machines industries, among others. With increasing market requirements of quality and precision, as well as in the course of global industrial modernization, Wilson decided to consistently increase its production systems in order to remain competitive over the long term.

Successful entry to finishing of wind turbines

“In 2013, we decided to enter precision machining for the wind power industry – the start of our collaboration with Starrag”, remembers Gao Wenjie, Deputy CEO of Wilson Machinery (Taixing) Co., Ltd. The extremely high requirements of shape and position tolerances could no longer be fulfilled with the existing machines. The large-dimensioned Dörries vertical lathes from Starrag provided the necessary precision and stability.

With the purchase of a Dörries vertical lathe with 4,000 mm diameter, Wilson laid the foundation for a successful development. Even after more than 10 years this machine continues to impress with high accuracy, efficiency, and reliability. “The excellent output of the Dörries machine far exceeded our expectations and supports the dynamic development in precision machining for the wind power industry and thus created a solid basis for further collaboration between Wilson and Starrag”, explained Gao Wenjie. “In 2024, when we were faced with the important decision of modernizing our machines, we immediately chose Starrag again and ordered nine machines, including Dörries vertical lathes and Heckert horizontal machining centers.”

Continuous development: Finishing of wind turbine components from Wilson takes another step forward

The Dörries vertical lathes fulfill not only the strict requirements of shape and position tolerances for precision components in wind turbines, but also significantly improve the product quality and production efficiency realized by Wilson thanks to their technical strengths. The linear drive systems designed for precision and heavy-duty cutting have hydrostatic guides.

This means that vibrations can be effectively reduced. Also in the case of long-lasting, high loads, these lathes retain their high rigidity and thermal stability and ensure continuous, high-precision output. Equipped with multifunctional tool heads, combined with a multifunctional tool magazine, they enable miscellaneous machining processes such as rotating, cutting, drilling, and grinding. Compared to similar machines, the machining efficiency is increased by more than 25%, whereby lead times for important components are reduced considerably. They also come with a flexible tool supply system for quick tool change and a modern digital control system. This enables automatic machining, reduces manual interventions, and improves production efficiency. “The output of these Dörries vertical lathes is crucial for the machining of large precision components in the wind power industry”, explained Zheng Weidong, Head of the Equipment Department at Wilson Machinery (Taixing) Co., Ltd. “The excellent precision and efficiency of the Dörries vertical lathes facilitated the entry into the finishing of wind turbine system components and will also continue to drive this development forward.”

Heckert horizontal machining centers: Precision in heavy-duty cutting

Production is complemented by Heckert horizontal machining centers, which are designed for high-precision heavy-duty cutting. They machine workpieces weighing up to 13 tons with exceptional accuracy. Straightness and flatness deviations under 7 μm as well as position deviations below 0.02 mm are achieved within a machining range of two meters. “The dimensional accuracy and surface roughness of the machined workpieces reach a new level and thus satisfy all our requirements in relation to product accuracy”, adds Zheng Weidong. In addition, both Heckert horizontal machining centers have a tower magazine for large and heavy tools. It allows tool diameters up to 950 mm, tool lengths up to 800 mm, as well as tool weights up to 50 kg, thus increasing the machining efficiency for demanding applications with high tool requirements considerably. Integrated anti-collision systems ensure high process reliability, efficiency, and stability. The efficiency of the Starrag machines speaks for itself and has made a significant contribution to the excellent production environment that Wilson has created. Wilson uses a unique foundation structure, which provides extreme stability. In conjunction with precise temperature control, it offers excellent conditions for many highly complex machining tasks, which can only be realized with difficulty for other machines and competitors.

“The excellent machines from Starrag are the driving force behind the improvement of our machining performance. They are not only unrivaled in terms of their output, but are also characterized by outstanding reliability and stability in long-term operation, allowing us to be optimistic about future development”, sums up Gao Wenjie.

Mutual cooperation: The start of a new era in precision machining

The cooperation between Starrag and Wilson is based on mutual trust and understanding, technical expertise, and the close correlation of both partners in relation to corporate culture and philosophy. “In the course of the collaboration the Starrag team demonstrated a high degree of professionalism and expertise. The team members not only used their global industry experience taking into consideration the characteristics of the Chinese market in order to provide professional advice, but also completed the installation and maintenance work on schedule and flawlessly in terms of quality and quantity, meaning we weren't faced with any worries”, says Gao Wenjie, praising the Starrag team. Tony Liu, General Manager of Starrag Group China, highlights that Wilson is a company that attaches huge importance to innovation, quality, reputation, and longevity. This clear positioning aligns very well with the corporate culture of Starrag. Thanks to the joint efforts of both sides, it was possible to establish high-precision, efficient, and stable production for wind turbines based on the local Chinese market. Starrag and Wilson will consolidate their partnership and continue to develop precision manufacturing. The next level is to be reached with innovative technologies and high-performance plants. Starrag looks forward to also working alongside Wilson in the future in order to further increase the high quality already achieved by the Chinese production industry and herald a new era of precision machining.
