The invention relates to a separately controlled multichannel carving and milling machine. The separately controlled multichannel carving and milling machine comprises a machine tool, a case, a left sliding door, a right sliding door, a control panel, a CNC (Computer Numerical Control) control system, a portal cross beam, a linear guide rail, a plurality of X-axis sliding plate mechanisms, a plurality of Z-axis sliding plate mechanisms, a plurality of Y-axis mechanisms, a plurality of workbenches and a plurality of tool changer disks. According to the separately controlled multichannel carvingand milling machine, main shafts and the workbenches can be separately controlled respectively, so that products can be synchronously or asynchronously processed by the main shafts, the products canalso be separately processed by the main shafts in multichannel different procedures, and the universality is good; the machining error of each shank cutter can be separately adjusted through the CNCcontrol system, so that the size of the produced products reaches the uniform standard, and the rate of good products is high; and the shank cutters of different specifications can be automatically replaced by the main shafts through the adjustment of the Y-axis mechanisms, so that the labor intensity of workers and the labor cost are reduced, the production cycle of the products is shortened, andthe production efficiency is high.
