摘要： A linear attuator of the present invention performs the fixing of a driving base by the primary fine means when the deflection of the moving velocity of the driving base in a driven direction and the moving velocity of the primary fine means driven by the secondary fine means in the driven direction becomes less than or equal to a specified allowable value, i.e., when the relating velocity becomes nearly zero, and moves the primary fine means driven by the secondary fine means in the direction opposite to that of the driven direction after not transferring the driving force of the secondary fine means to the driving base when the driving base is separated from the primary fine means. Thus, the driving base can be driven by a stroke longer than the driving stroke of the fine actuator itself at a specific velocity and it can be driven smoothly.

摘要： A numerically controlled lathe capable of machining a workpiece by numerically controlling a machining table provided with a machining tool. In order to prevent a local uneven abrasion of parts, which make a sliding contact, due to a mass production of workpieces having a simple form or a machining in a non-circular shape, there are provided a main carriage and a sub carriage. A machining tool is positioned on the sub carriage, and the sub carriage traverses on the main carriage along an axis which the main carriage and the sub carriage have in common. When a circular machining is carried out, the main carriage and the sub carriage respectively traverse by an equal amount in directions opposite to each other, and the cutting tool is constantly maintained at a position designated by an instruction. At the time of a non-circular machining, the main carriage and the sub carriage respectively traverse in directions opposite to each other; moreover, the sub carriage rapidly traverses in response to an instruction designating a location of the tool. Thus parts which make a sliding contact are evenly worn out by shifting the relative positions of both the main and sub carriages.
摘要翻译：一种能够通过数控加工工具加工台加工工件的数控车床。为了防止由于大量生产具有简单形状的工件或以非圆形形式的机加工而产生滑动接触的部件的局部不均匀磨损，设置有主滑架和副滑座。加工工具位于副托架上，副托架沿着主托架和副托架具有共同的轴线在主托架上运动。当执行圆形加工时，主托架和副托架分别在彼此相反的方向上横过相等的量，并且切割工具始终保持在由指令指定的位置。在非圆形加工时，主托架和副托架分别沿彼此相反的方向横移; 此外，副托架响应于指示工具的位置的指令而快速地穿过。因此，通过移动主滑架和副滑座的相对位置，使滑动接触部件均匀地磨损。
