Foshan City, Nanhai District Huidexing Stainless Steel Products LTD., , https://www.huidexing.net At present, the gantry planers still in use are mostly products of the 1960s and 1970s. The electrical control methods are backward, the devices are seriously aging, the processing efficiency is low, the power consumption is high, the faults are frequent, and the maintenance is difficult. To this end, we have carried out technical transformation of the main drag of the B2010A planer. The load nature of the main drag speed control system is shown in Figure 1. In the figure, F_m represents the maximum cutting force, Ï… represents the cutting speed, and P_(m1) represents the maximum cutting.
