ーリ部の発熱については配慮がなされていなかった。Mumei [Tera Shizuku's background] Conventionally, the spindle drive motor or x, y, and z-axis feed motors of machine tools have either been directly attached to structures such as the spindle head, column, or saddle, or have been installed with insulation material. However, the heat generated by the motor was transmitted to the structure. Also,
Even if it is installed through a heat insulating material, the time it takes for it to be transmitted to the structure is delayed and the effect of blocking one heat generation is small. This causes problems such as thermal deformation of the structure and unstable machining accuracy of the machine tool.Also, in recent years, spindle speeds have increased and belt drive of the spindle has been frequently used, but heat generation in the pulley section was not considered.
