How many transmission modes are there for general-purpose втвърдяващи машинни инструменти? Which is more stable?

According to the main transmission type, it can be divided into hydraulic type and fully mechanical type. Hydraulic transmission has the advantages of simple structure, large driving force and fast moving speed (up to 150mm/S). With the shortcomings of unstable moving speed and low positioning accuracy, hydraulically driven induction втвърдяващи машинни инструменти are gradually being eliminated. Fully mechanical transmission is divided into various transmission forms such as T-shaped screw, ball screw, and linear moving guide. The fully mechanical transmission has the advantages of fast moving speed, high positioning accuracy, and easy variable speed movement.

According to the mechanical structure of the moving part, it can be divided into two types: sliding plate type and guide column type. The skateboard type is the second structural form with the largest number of applications in my country. Its bed often adopts an aging-treated cast or welded structure. It has a large bearing capacity and good stability. It can process larger and heavier workpieces and has the widest application range. This form has the disadvantages of heavy bed, inflexible sliding, and complicated guide rail processing. The guide column structure is more common in European and American countries. The main advantage of this structure is that the machine tool is light in weight and flexible in movement. It is easy to realize the integrated design with the quenching liquid circulating cooling system, but it is not suitable for the processing of large and heavy workpieces. The stability is slightly worse when it is large (such as the vibration of the workpiece).
