Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other co...

Abstract

The invention discloses a leaf-disk-type part processing system and method based on arc discharge and milling combination. The roughing processing of a leaf-disk-type part is completed by using the negative arc processing, most of the to-be-removed material is removed, semi-finishing processing of the leaf-disk-type part is completed by using positive arc processing, finally, finishing processingof the leaf-disk-type part is completed by using milling processing, and step by steps processing is completed on the same machine tool. By means of the method, the processing efficiency of the leaf disc of the difficult-to-process material is significantly improved, the processing time is significantly shortened, the cheap graphite electrode is replaced with the expensive tool in the roughing andfinishing process, the processing cost is reduced, the processing process is completed with the high quality in one special machine tool, the integration of arc discharge processing and milling processing is achieved, and the processing steps are less.

Description

technical field [0001] The invention relates to the processing technology of blisk parts, in particular to a processing system and method for blisk parts based on the combination of arc discharge and milling. Background technique [0002] Most of the existing blisk parts processing technology uses special cutting tools for difficult-to-machine materials for rough and finish machining. However, due to the poor characteristics of titanium alloys and nickel-based superalloys during processing, the tools are inevitably worn out and the use time is extremely limited. Such tools are often expensive, and frequent tool replacements lead to rising processing costs, which greatly increases Its application cost; at the same time, titanium alloys and nickel-based superalloys also have problems such as lengthy processing time, and the processing accuracy cannot be effectively guaranteed during continuous processing, which cannot be effectively solved by traditional cutting processing. ...
