三、几种机床液压系统的设计 (一)珩磨机床液压系统的设计1.珩磨机对液压系统的要求 (1)主轴回转速度应保持恒定,主轴往复行程的速度要均匀一致。主轴回转和往复速度在加工过程中应能无级调节。为使运动平稳,主轴最低往复速度可限制在1.5～3米/分,最高速度不大于20～25米/分;
Third, the design of several machine tool hydraulic system (A) the design of honing machine hydraulic system 1. Honing machine hydraulic system requirements (1) the spindle rotation speed should be kept constant, the spindle reciprocating stroke speed should be uniform. Spindle rotation and reciprocating speed in the process should be able to stepless adjustment. In order to smooth the movement, the minimum reciprocating speed of the spindle can be limited to 1.5 ~ 3m / min, the maximum speed is not more than 20 ~ 25m / min;
