In May 2017, 1SC (www.rusmachine.ru) has finished modernization of vertical turning lathe, model 1525F1 with digital read out system – DRO. Maximum processing diameter is 2500 mm, height is up to 1600 mm, workpiece weight is up to 16 tons.
Main reducer and side feeding boxes with a large number of electromagnetic couplings were replaced with modern servo drives with a wide range of speed control. For torque increase small-size planetary reducers which don’t require maintenance were installed on axes.
