CNC single-column once-formed rail grinding machine succeeded in Hanghang
Hangzhou Machine Tool Group has successfully developed a CNC single-column single-form lathe bed guide rail grinding machine for Dalian Machine Tool Group. This advanced machine features a single-column grinding head mobile layout, which enhances flexibility and precision during the grinding process. The main spindle is equipped with a dynamic and static pressure bearing system, ensuring smooth operation and high stability. The grinding head motor delivers 45 kW of power, enabling efficient material removal while maintaining accuracy.
The machine uses a combined grinding wheel structure, with the largest grinding wheel span reaching up to 500 mm, allowing it to handle a wide range of workpieces. A notable innovation is the first desktop hydraulic and mechanical combined profiling grinding wheel correction device. This system utilizes a secondary hydraulic cylinder for vertical profiling, while transverse movement is achieved through mechanical transmission. The result is a highly responsive and accurate correction process, ensuring consistent quality in every operation.
Equipped with a two-axis numerical control system, the machine offers excellent positioning accuracy, making it ideal for complex machining tasks. It can grind and shape the lathe bed or saddle rail surface in a single operation, significantly improving both efficiency and precision. This advancement not only reduces production time but also enhances the overall performance of the machine tool, meeting the demands of modern manufacturing industries.
