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 machining, and relates to the finishing process of the profile surface of the integral blisk blade of an aero-engine, in particular to an electrolyte-plasma processing device and method for polishing the profile surface of the integral blisk blade. Background technique [0002] The principle of electrolytic machining is to use the anodic dissolution of metal in the electrolyte to remove the material and process the parts into shape, which is called "electrochemical machining" (ECM) abroad. Electrolyte-plasma processing is an internationally leading electrochemical processing method. This processing method can be used for metal surface finishing, deburring, sharp edge rounding, etc. It can improve the surface roughness by 2 to 3 levels, and effectively improve the surface integrity of parts. Electrolyte-plasma processing is a process consisting of two parallel stages in the electrolyte: 1. Using the inter...
