Overview

Bed: This series of machine tools adopts a flat overall bed, which is cast by sand-type technology. The internal ribs have a reasonable layout, the guide rails are wide, and the overall rigidity of the bed is high. It adopts medium frequency quenching, the hardened layer is 2~3mm deep, the hardness is above HRC52, and the saddle and slide sliding surface are plasticized, so that the dynamic and static characteristics of the feed system are in the best state, because The dynamic and static friction coefficients are close, which reduces the occurrence of low-speed crawling; the double-triangle guide surface makes the machine tool rigid, resists vibration and deformation, and allows users to obtain higher machining accuracy and faster moving speed. High production efficiency.
Main drive system: The headstock of this series of machine tools is hydraulic automatic shifting. Its main shaft bearings are made of precision spindle bearings at home and abroad. They are lubricated with external circulation lubricating oil, which can effectively control the temperature rise of the main shaft. In addition, the internal transmission parts of the headstock are taken outside the body. The circulating lubricating oil is lubricated, and the heat dissipation effect is good, so that the heat generated during the operation of the headboard can be fully and rapidly diffused to the outside. When designing the headboard, the spindle precision and rigidity are improved. The advanced processing equipment ensures the machining precision of the headstock, the spindle and various parts. When assembling, the spindle bearings are pre-tightened and the preload is ensured. The assembled bed box has the characteristics of low temperature rise, small thermal deformation and high precision, so that the spindle can maintain relatively stable precision when working for a long time.
