Compared with traditional power, hydraulic power has the characteristics of strong power, low fuel consumption, low noise and good comfort.
A few days ago, the world's leading diesel engine manufacturer: Shandong Weichai's first hydrostatic powertrain has made significant new progress and successfully achieved mass installation, which also marks Weichai's strength to lead a new round of upgrading and reform in the loader industry.
Among them, the Linde hydraulic motor casing, hydraulic pump casing and hydraulic pump distribution plate casing that make up the hydraulic power are processed and produced by SDSB Precision Technology Corporation.
"Hydraulic parts have very high requirements on our processing accuracy, and the accuracy of hydraulic products must reach 6 microns," Dr. Zhang, CTO of SDSB, introduced to us. In order to meet the processing of hydraulic products, the company has successively introduced more than 30 processing equipment, including Including several German GROB high-precision machining centers.
Hydraulic parts have high requirements on tightness, which makes their machining accuracy requirements higher.
"It is unavoidable to produce small burrs during the machining process of the workpiece, but Linde hydraulic products have very high requirements for machining burrs." In view of the product characteristics, Dr. Zhang led the R&D team and tool manufacturers to redesign the tool. Numerous experiments have led to the development of a new type of cutting tool, and a new process of explosive deburring has been adopted to efficiently remove machining burrs without affecting the performance of the parts, meeting customer requirements.
With the continuous improvement of the R&D team, the company has made great progress in hydraulic parts processing tooling, processing technology, deburring technology, etc., and the technical means have been continuously improved. The company has introduced a German Zeiss CMM with a calibration accuracy of 0.9 microns, which can meet the requirements of automatic needle change and quick needle change, which greatly improves the measurement efficiency of the product.
