Design of electrical control system of a milling machine (control circuit diagram only)

Project: Design of electrical control system of a Milling machine Time: 1 day only the circuit diagram Course design technical instructions and control requirements 1. Description of the movement of the mechanical part of the equipment A certain type of horizontal universal milling machine is mainly composed of a base, bed, suspension beam, tool holder, table, skateboard and lifting table. There are three forms of movement: the rotational movement of the spindle and the milling cutter is the main movement; the feed movement is the movement of the workpiece driven by the workpiece in the processing or the rotational movement of the circular table; and the auxiliary movement is the rapid movement of the workpiece in three directions by the workbench. 2. Equipment electrical control requirements and technical parameters 1) The spindle and the table are each dragged by a separate cage-type asynchronous motor 2) Spindle motor M1 requires forward and reverse, with parking brake control 3) The feed motor M2 requires forward and reverse, and there is interlock protection between the three directions of feed movement 4) The workbench has a fast movement control 5) The spindle rotation and table feed are controlled sequentially 6) The cooling pump is dragged by the motor M3 7) Necessary protection links, chain links, lighting and signal circuits 8) The power of the motor M1: 7.5KW M2: 1.5KW M3:0.125KW
