Abstract

The invention provides machining device and method for polishing the blade profile of an integrated bladed disk by applying electrolyte-plasma machining technology, which is characterized in that: an integrated bladed disk work-piece 4 is located and clamped on a machine tool spindle 20, and the integrated bladed disk work-piece 4 is connected with the positive pole of a power supply; a blade part is soaked in an electrolyte 17 in a machine tool working pool 14, and the electrolyte is connected with the negative pole of the power supply; the spindle 20 starts to rotate with a rotational speed N and drives the bladed disk to rotate; and process parameters are set and then polishing machining for the blade profile is performed. The machining device and method for polishing the blade profile of an integrated bladed disk has the following advantages that: continuous machining, efficiency increasing and uniform machining surface can be realized; as well as the automation of polishing machining for the blade profile of integrated bladed disk and batch production with high efficiency and low cost can also be realized.

Description

Technical field [0001] The invention belongs to the field of electrical processing, and relates to the finishing processing of the integral blisk blade profile of an aero-engine, in particular to an electrolyte-plasma processing device and method for polishing the integral blisk blade profile. Background technique [0002] The principle of electrochemical machining is the process of using metal to dissolve anode in the electrolyte to remove materials and forming parts. It is called "electrochemical machining" (ECM) abroad. Electrolyte-plasma machining is an internationally leading electrochemical machining method. The machining method can be used for metal surface finishing, deburring, sharp edge rounding, etc. It can increase the surface roughness by 2 to 3 levels, and effectively improve the surface integrity of the parts Improve anti-fatigue performance; Electrolyte-plasma processing is a process composed of two parallel stages in the electrolyte: 1. Using the interaction betw...
