Problems solved by technology

However, titanium alloy is a difficult-to-cut material, especially for processing slender shafts, which is even more difficult
At present, the commonly used modern processing methods are also difficult to meet and meet the processing requirements of titanium alloy slender shafts. For example, laser processing will produce a remelted layer, which cannot meet its metallurgical requirements for materials; the efficiency of EDM is lower than that of laser processing, and remelted layer

Abstract

The invention discloses an electrochemical machining method for a titanium alloy slender shaft. The method comprises the steps that one end of a titanium alloy workpiece to be machined is fixed to a triangular chuck of a machine tool, and a cathode clamping tool fixes a copper pipe cathode; the copper pipe cathode is moved to enable the titanium alloy workpiece to be machined to penetrate into the copper pipe cathode, it is guaranteed that the titanium alloy workpiece and the copper pipe cathode are insulated from each other, and the radial clearances between the titanium alloy workpiece and the copper pipe cathode are maintained to be identical; electrolyte is fed into the position between the titanium alloy workpiece and the copper pipe cathode, and the titanium alloy workpiece is rotated for electrochemical machining. According to the electrochemical machining method for the titanium alloy slender shaft, the copper pipe cathode is a brass pipe body, an end cap is arranged at one end of the pipe body, the other end of the pipe body is a clamping part, and two electrolyte feeding ports are formed in the head end and the side wall of the clamping part. The titanium alloy slender shaft is machined through the method and equipment, production efficiency is improved greatly, the surface roughness of the machined titanium alloy slender shaft is improved obviously, meanwhile, the machined titanium alloy slender shaft hardly deforms, and the yield of products is improved.

Description

technical field [0001] The invention relates to an electrolytic machining method and processing equipment, in particular to an electrolytic machining method and processing equipment for a titanium alloy slender shaft. Background technique [0002] The processing accuracy of the slender shaft mainly includes dimensional accuracy, shape accuracy, position accuracy and surface roughness. The processing of the slender shaft is more difficult. During the processing, the processing system will produce different degrees of deformation under the action of external forces such as drilling force, cutting force, clamping force, transmission force, gravity, inertial force, etc., so that the tool The relative position between the workpiece and the workpiece changes, resulting in machining errors. In addition, in the turning process, the processing system composed of the lathe-fixture-tool is prone to vibration of the processing system, and the above factors will affect the processing ac...
