The temperature of a chemical liquid supplied to a pot is detected while allowing a processing liquid discharge port to discharge the chemical liquid toward the pot at a pre-dispensing position. The temperature of the chemical liquid rises in response to the lapse of time. When the temperature of the chemical liquid supplied to the pot reaches a second target temperature, the processing liquid discharge port is allowed to stop the discharge of the chemical liquid. Thereafter, a positional relationship between the processing liquid discharge port and the pot is changed, and the processing liquid discharge port is allowed to discharge the chemical liquid toward the substrate at the processing position.

The invention discloses an artificial joint-like piece curved surface turbulence simulating polishing device and a method thereof. The device comprises a glass constraint component, a profiling electromagnetic wave heater, a temperature detection device, a supporting frame and an electromagnetic wave controller, wherein the glass constraint component is arranged outside an artificial joint-like piece in a sleeving way; the inner surface of the glass constraint component and the curved surface of the artificial joint-like piece form a profiling runner with uniform thickness; the profiling electromagnetic wave heater is arranged on one side of the glass constraint component; the profiling electromagnetic wave heater comprises an outer cover, heating sources, a concave lens and a convex lens; and each heating source of the profiling electromagnetic wave heater is electrically connected with the electromagnetic wave controller and is independently controlled by the electromagnetic wave controller. One heating source is placed on the side surface of the glass constraint component, the turbulence energy and the speed of abrasive flow cutting fluid are increased, and the linear loss and the head loss of the abrasive flow in the profiling runner are compensated, so that the whole processing effect is improved and the surface processing quality of the artificial joint-like piece is more uniform.
