The invention provides micro-channel processing equipment of a microfluidic chip; the lower end of a bracket is connected with a numerical control objective table with multiple freedom degrees, a rocker arm is arranged on the bracket, an engraving depth control scale is arranged on the rocker arm, a micro-size cutter numerical control movement mechanism is arranged on the engraving depth control scale, the upper end of a heater is connected with the lower end of the engraving depth control scale, the upper part of a micro-size cutter is arranged in the heater, and a temperature controller is connected with the heater by a lead. In the micro-channel processing equipment, the temperature control heating and a micro-machining device are combined, numerical control programming is adopted to ensure to process a complex channel graph while ensuring the needed processing precision, so as to simplify the processing technique of the microfluidic chip and shorten the processing time. The cutterhas long service life, and the positioning precision is high, so as to be convenient for batch production for the microfluidic chip. The channel planeness and the linearity of the manufactured microfluidic chip are good. The processing method for the micro-channel processing equipment is simple and easy.
