Scroll plate processing method, control device and scroll plate processing device

The invention discloses a scroll plate machining method, a control device and a scroll plate machining device, and belongs to the technical field of scroll plate part machining. The scroll plate machining method comprises the steps that a workpiece is clamped on a clamping jaw plate, the clamping jaw plate is driven to rotate, a cutter is driven to rotate to provide cutting force, the cutter is driven to do linear motion in the first preset direction, the workpiece is roughly machined into a scroll plate, a grinding wheel is driven to move, the roughly machined scroll plate is accurately ground, and the finely machined scroll plate is obtained. According to the technical scheme, primary machining of rough milling is conducted on the workpiece through the cutter, then precision machining of fine grinding is conducted on the workpiece through the grinding wheel, machining from rough to fine is conducted step by step, therefore, the requirements for machining precision and surface roughness are met, the cutter i
