In the production site of Unisys Smart Equipment Co., eight i5 intelligent machine tools are ready to be sent to the United States Rassini's Mexican plant.
Rassini is the world's largest designer and manufacturer of suspension and brake components for the automotive industry. It is the world's largest manufacturer of suspension components for light commercial vehicles and the only manufacturer of vertical integrated brake discs in the United States. There are multiple production bases in North America and Brazil, and it is the GM host supplier. Rassini will use the machine tools from China for the first time to process brake discs.
In April 2017, Rassini's first batch of blanks was tested in Shenyang machine tool, and the accuracy was in full compliance with the requirements of American customers. The i5 intelligent machine tool gained initial trust from customers. In July, the brake team visited Rassini company in Michigan, USA. Factory, During the exchange, Rassini engineers expressed their full agreement with the intelligent manufacturing concept of Shenyang Machine Tool and believe that intelligent manufacturing is the future trend. Open technology route, natural Internet terminal, 3D simulation, process support, feature programming, graphic diagnosis, intelligentization Customized tools, i5 intelligent machine tools, these unique intelligent features are also valued by American engineers. The brake disc team also learned in the depth of communication Rassini brake processing automatic line processing speed requirements, this time to buy new equipment, hope that the automatic line processing The beat is compressed from 70 seconds to 50 seconds, that is, an automatic line consisting of 3 lathes and 1 vertical machining center. Each sequential machining time in 4 steps does not exceed 50 seconds.
The data obtained by the brake team during the first sample processing in April was that the four-step beats were 30 seconds, 43 seconds, 53 seconds, and 60 seconds. Optimizing the process and balancing the beats became the main task of the brake team. They Decided to control the stand-alone processing tempo within 45 seconds. In July, after two optimizations, the longest addition sequence was reduced by 18 seconds, and the tempo of each track was controlled between 38 seconds and 42 seconds.
'Incredible job!' In August, Rassini's engineers came to the production site of Shenyang Machine Tool with a detector and a stopwatch. After 50 consecutive cutting samples were tested, they gave such praise. 50 samples. Pieces, processing cycle, precision, finish, all meet the requirements.
In September 2017, Rassini signed eight i5 intelligent machine tools contracts with Shenyang Machine Tool. There are still procurement requirements for the follow-up. This signifies that the i5 intelligent machine tool has taken the first step towards the world in the brake disc industry.
